tomcat 3.2.4
Hi folks, I'm new to the list, so I apologize in advance for any faux pas I may commit here! The question is simple - we'd like to get the 3.2.4 release of Tomcat, but do not see a download link on the Apache site. Is it archived somewhere? I know it's old, but we haven't moved to the new architecture yet. Many many thanks! Regards, Steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Options to prevent web app from being available if DB not available?
Mike, Doing this with pure J2EE Servlet code, I would use three components. First, use the Context Listener to check the Database on start up, if no DB connectivity set a ApplicationContext attribute to that effect. The second part would be a javax.servlet.Filter which checks the status of the ApplicationContext attribute forwarding to an error page if the attribute indicates database connectivity issues. Third, instead of just a String, I'd use a self-updating object as the attribute in the ApplicationContext. This self updating object runs an internal timer thread which tests connectivity at a fixed interval setting the DB status to up or down. This third component is optional. Regarding your issue not wanting to start certain servlets if the Database is down, you could carry out a DB connectivity test in the base class to all your servlets, skipping initialization if no connectivity. Steve Mike Miller wrote: Hi, I am looking for options to prevent my web application from being available if our database is not available. I've used context listeners in the past, but since you can return a bad return code they don't like the cleanest approach.

Re: classloader issue on jboss3.2.2 for tomcat4.1
It doesn't see any classes in any of your jars? I was using JBoss 3.2.2 back in 2003 and had the same issue. Once I set the web loader to false, I realized that some utility classes were getting loaded from jars deployed in other wars. Effectively, now each webapp has its own classloader. So, I had to add those same jars into all my wars. On a side note, JBoss 4.0.x does a much better job with this. Steve lio tomcat wrote: Hello world, For some reason, i had to change default conf of my jboss 3.2.2 in order to avoid the use of jboss class loader.

Re: Two Service elements problems
I couldn't find it in your post, so let me ask. Do you have 2 network interfaces on the machine? How are you establishing 2 ip addresses? This topic sparked my interest because I will also be doing the same thing. Now, to answer your question more definitively.I put together a mock setup using a 5.0.30 distro I had laying around (WinXP). I took the default server.xml listening on localhost and added the following service element: Service name=Catalina2 Connector port=8081 address=littlehost maxThreads=150 minSpareThreads=25 maxSpareThreads=75 enableLookups=false redirectPort=8443 acceptCount=100 debug=0 connectionTimeout=2 disableUploadTimeout=true / !-- Define the top level container in our container hierarchy -- Engine name=Catalina2 defaultHost=littlehost debug=0 !-- Global logger unless overridden at lower levels -- Logger className=org.apache.catalina.logger.FileLogger prefix=catalina_log. suffix=.txt timestamp=true/ Host name=littlehost debug=0 appBase=l_webapps unpackWARs=true autoDeploy=true xmlValidation=false xmlNamespaceAware=false Logger className=org.apache.catalina.logger.FileLogger directory=logs prefix=littlehost_log. suffix=.txt timestamp=true/ /Host /Engine /Service I don't have a second network interface, so created a second host name littlehost to my actual ip address through /etc/hosts. Started tomcat . , my netstat confirmed that I was listening to port 8080 on localhost and port 8081 on littlehost. But, when I go to http://littlehost:8081/ nothing happened. Then I followed the directions at http://www.ex-parrot.com/~pete/tomcat-vhost.html for setting up a virtual host. Using that reference I did this: 1. Added a ROOT.xml file in conf/Catalina2/littlehost 2 Created the l_webapps directory specified by my Host element. 3. Created a web application deployment structure in the l_webapps directory 4. Created an index.jsp at the root of l_webapps Restarted tomcat .. now http://littlehost:8081/ servers up content.

Re: Virtual Hosts
You probably want to change the appBase. You can control the contexts by creating a context snippet in conf/[Engine name]/[Host name] or add it to META-INF/context.xml in each war.

Re: Two Service elements problems
Brian, On more follow up. I found a usb wireless network adapter that I forgot I had. The server.xml snippet below stayed the same, except I had to add the address attribute on the original http connector element. I opted to use the Ip addresses instead of messing with /etc/hosts this time. Now I have . Service name=Catalina Connector port=8080 address=192.168.0.2 etc etc... Service name=Catalina2 Connector port=8080 address=192.168.0.5 etc etc... netstat -an (snippet) TCP192.168.0.2:8080 0.0.0.0:0 LISTENING TCP192.168.0.5:1390.0.0.0:0 LISTENING TCP192.168.0.5:8080 0.0.0.0:0 LISTENING It serves content on both IP addresses with the same port. Steve Barnett, Brian W. wrote: Thanks Steve. I will try that. Regarding your question to me, I have tried two different approaches. My first approach was to bind an additional IP address to the one NIC I had in the XP box using the Advanced button in TCP/IP setup for the NIC. I struggled through that for a few days, then decided to put in a second NIC. I struggled to get that working for a few days and ended up going to back to two IPs bound to a single NIC. Since I have not yet got it working the way I want it to work, I can not say definitively whether either of those approaches worked, although from my research either *should* work. There are advantages/disadvantages to each. Things to consider are bandwidth sharing, if a NIC goes down you lose both IPs or just one, etc. Again, thanks for your input!

[...] Has anyone managed to serve JSP with Tomcat on a RHEL4 machine running their stock httpd? You're looking for mod_jk RPM or mod_jk2 (which has been dropped from development). I found mod_jk-ap20-1.2.10-1jpp.i386.rpm at http://www.jpackage.org and It installed without error on RHEL4 running stock httpd-2.0.52-9.ent.rpm So far, so good. So I added the suggested element Listener className=org.apache.jk.config.ApacheConfig modJk=/usr/lib/httpd/modules/mod_jk.so / to the Engine name=Catalina ... container in server.xml and restarted Tomcat. This created /usr/local/jakarta-tomcat-5.5.9/conf/auto/mod_jk.conf (NOT mod_jk.conf.auto as the Jakarta Tomcat Connector Apache HowTo documentation says). The mod_jk.conf was pretty skeletal, so I added: JkWorkersFile /usr/local/jakarta-tomcat-5.5.9/conf/workers.properties and edited workers.properties to reflect the locations workers.tomcat_home=/usr/local/jakarta-tomcat-5.5.9 workers.java_home=/usr/java/jdk1.5.0_03 and added this line to /etc/httpd/conf/httpd.conf Include /usr/local/jakarta-tomcat-5.5.9/conf/auto/mod_jk.conf and finally restarted Apache. No error, but it doesn't do anything meaningful with my JSP files: it just serves them through Apache. Looking in mod_jk.conf I see it mentions all the subdirectories in Tomcat's webapps directory, but nowhere does it reference any directories in my Apache document tree. I've obviously missed how to get it configured to serve JSP files from the Apache web server directories. I have no interest in serving any JSPs from the Tomcat directories, as all I use Tomcat:8080 for is serving Cocoon, which already works fine. The JkMount directives in mod_jk.conf all refer to /directory being in Tomcat's webapps directory. How do I reference directories which are actually below /var/www/html so that they get handled by Tomcat? In mod_jk.conf, what does this refer to: VirtualHost localhost ServerName localhost The Tomcat:8080 server or the Apache httpd:80 server? If it's Tomcat, then I can understand why JkMount /directory refers to Tomcat's webapps, but it seems very weird that the autoconf should configure mod_jk.conf to mount only Tomcat's directories, when the entire point of the operation is to enable serving of Apache's own JSP files. If it's Apache's httpd, which it is presumably intended for, as this file gets Include'd from Apache's httpd.conf, then why does it still refer to localhost instead of picking up the ServerName from the httpd.conf? Should I change both localhost's to my server's FQDN? ///Peter Peter, 1. VirtualHostis an apache http server directive. 2. With JkMount you're not actually mapping a physical directory, it's a url pattern. If you have a tomcat webapp that serves jsp's such as http://localhost:8080/mywebapp, then you can map jsp requests to that webapp using JkMount /mywebapp/*.jsp Hope that helps, Steve - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Newbie: Installing Admin on Tomcat
Assuming you are configured to use folder names when you unzip, doing so will essentially create a directory structure that is parallel to the default Tomcat installation (C:\Program Files\Apache Software Foundation\Tomcat 5.5) Just unzip the Admin files into their own, separate directory, then copy everything from its 'root' and overwrite the existing TomCat installation directories...it really is that simple. If you are comfortable enough and you know what you are doing, you can extract straight into the TomCat Installation directories, but I'm more comfortable taking the extra steps and then cut-and-paste. -Original Message- From: Bruce E.

Newbie Virtual Host Question
Help! I'm sure my problem boils down to simple syntax, but I've been wrestling with it for days so its time to ask... I'm running a default installation of Tomcat 5.5.9 on Windows XP purely for development/training purposes. As a matter of principal I like to keep all my data separate from my other files, so my web sites are all stored under C:\Data\CurrentProjects\ProjectName. All I want to do is to configure Tomcat to see these sites in their current location rather than deploy them into the Tomcat file structure, but I can't seem to get it edited correctly in the server.xml file. For now these are basic web sites with some SSI and CGI. I had this all running smoothly with an earlier version of Tomcat, but hardware problems wiped out that configuration and I can't seem to get it working again. I've edited my hosts file to reference my local development sites, but the best I've been able to manage so far is to get my own site address to return the default Tomcat pages. Everything else returns some variation of a page not found error. An example of the correct Virtual Host definition (context/apBase/docBase syntax, and anything else I might be missing) to point Tomcat at sites in another directory (under Windows) would be greatly appreciated.

Repeated logging problem on 5.5
I have a double-logging problem, by which I mean that some of my log messages get logged to two logfiles. I have only one logfile configured using java.util.logging, but in some cases, the same log message gets logged to the TC stdout log as well, which I don't want. It's not the end of the world, but I'd like to understand what's happening in case I've misunderstood something. This problem only happens when there is a java.util.logging call from either: - the init() method of my own servlet - a class created during that init() method, that persists in the VM after the init() method has returned, through a static field reference. I asked about this approx 1 days ago, but got no replies, probably because my original post was too wordy. More detail, incl my versions and config setup, are in my original post here: http://article.gmane.org/gmane.comp.jakarta.tomcat.user/113877 Does anyone have any ideas what the cause might be, please? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: tomcat 5.5.9 does not read context.xml
yes context.xml is fine in META-INF. in fact it is preferred over having it in server.xml. your alternative is to put it in conf/enginename/hostname/yourwebappname.xml (which is in fact what TC will do for you when it unpacks the war). I don't know that you can have the context path name different to the war file. I'm not 100% sure, but can't see how to do it. in fact I can see it being a source of potential confusion. can you explain why you want to do that? OK, I am totally confused. Is or is it not best practice to provide a context.xml in META-INF. I thought this was required for hot deployment to work. If I want my context path to have a different name to my war file, how do I achieve this? thank you - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

A couple DOM classes (don't remember which ones, but you'll know it if you run in to them) had some methods added in jdk 1.5. If you try to load an implementation class for one of these that was developed in jdk 1.4, you'll get missing method implementation errors. To resolve, you can add empty method specifications for the classes that require them, or upgrade to an XML parser that was written for jdk 1.5. 2. JDK 1.5 uses the symbol enum as a reserved keyword. You'll have to change any and all occurrences of this symbol in your code (where it is used as a variable name) to something else, e.g. enumer. There may be other backward compatibility issues, but these are the two that I've run into. -Mark Tim Diggins wrote: And, oops, I'm sorry for spreading the original FUD - Following this thread, I've just tried again to get everything working on tc5.0/jdk1.5 and hey-presto, everything ok - guess I must've had TC running on jdk1.4 after all...

RE: my build structure..opinions wanted
Don't leave the source on the production server, but it's fine in development. Strictly speaking your source files are inaccessible by web clients if they are under WEB-INF, but better safe than sorry. Why not store the src in another folder altogether - eclipse won't care where it is presumably, and this is slightly better practice. The other approach is to build a jarfile from a build script (e.g. using ant), then copy the jar to the webapps/ directory, TC will auto-deply it. Some would say this is the only way to do it. However it does slow things down when you are making frequent small changes to code. For my money, the value of a jar is ease of portability, which is a factor if you are writing for true cross-container support. I built classes direct to classes/ for a long time, then made the effort to switch to jar deployment in development, after being persuaded by people on this list. I'm glad I've done both, but to be honest I think I do prefer building to classes, as it's quicker and I can't see a disadvantage to it during dev. Your approach that sounds a quite practical solution to me. Does eclipse precompile JSPs for you too? One other thing to watch is that logging.properties and properties files go in the classes/ folder, so if you use these, be careful that eclipse does not delete them when rebuilding your classes. -Original Message- From: gabor [mailto:[EMAIL PROTECTED] Sent: Friday 27 May 2005 13:16 To: tomcat-user@jakarta.apache.org Subject: my build structure..opinions wanted hi, i'm starting a project using jsp + javaBeans.. i've worked with java a lot, but i have not much experience with web applications.. for now my idea is that the application will be using javabeans, and jsp for displaying the data... i use eclipse for the development, which nicely compiles every source file automatically when i edit them. that's why i came up with the following idea: i'll create a directory in tomcat/webapps (let's call it 'mywebapp'). put my source files into mywebapp/WEB-INF/src, and instruct eclipse to put the compiled .class files into mywebapp/WEB-INF/classes. this way, i simply edit the files, press ctrl-s (to save them), switch to the browser window, and press refresh, and already i get the new results (because eclipse already compiled the file, and tomcat detected the change). i tested this approach, and it works ok. is this a suitable approach? are there any dangers with this approach? gabor - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: jspServlet runs out of memory while compiling some jsp files using fork=true
When you say this: The jsp pages are quite large, 5000-1 rows and there are many of them. I take it that you mean that the page can display 5-10k rows of data from a database, rather than the JSP has 10k lines of code in it. I hope so. If not, it's no wonder that the compiler is struggling!! If you do mean DB rows rather than lines of code, I still don't see a particular reason why compiling the JSPs should present such a heavy load if, as you say, you are only changing a few at a time. It sounds more likely to me that it is the processing of the request by the JSPs that is probably eating up the server resources. If compilation is happening in parallel with this, maybe the two together are enough to push the performance off the edge? -Original Message- From: Vesa Varimo [mailto:[EMAIL PROTECTED] Sent: Friday 27 May 2005 14:16 To: Tomcat Users List Subject: Re: jspServlet runs out of memory while compiling some jsp files using fork=true Hmh.. how does you deployment script work?

RE: my build structure..opinions wanted
Precompiled JSPs do 2 steps - JSP to Java, then Java to pcode, which can then be run by TC. The compiled JSPs end up as class files, mine end up in in the %catalina_home%\work\[enginename]\[hostname]\[webappname]\org\apache\jsp\WEB _INF\jsp directory (because the source JSP files are in WEB-INF\jsp). Without precomp, TC compiles each JSP on the fly, the first time that it is accessed, which slows down execution. I've never used Eclipse so was just interested. NetBeans does not by default do precomp, or even auto compile of servlets on save, although because it is based on Ant, most things are possible with a little scripting. -Original Message- From: gabor [mailto:[EMAIL PROTECTED] Sent: Friday 27 May 2005 15:12 To: Tomcat Users List Subject: Re: my build structure..opinions wanted On Fri, May 27, 2005 at 01:29:50PM +0100, Steve Kirk wrote: Your approach that sounds a quite practical solution to me.

RE: Adding content/JSPs on the fly
It sounds reasonable, but probably isn't tested or by design, so probably best to just have a go. Re portability, the best advice I can offer is an old chestnut: read the servlet spec. This is particularly relevant in this case. The spec is generally pretty good at telling you you pretty accurately if (a) what you want to do should/must be supported or (b) what you want do do is forbidden. Of course there are some areas that it does not have a view either way on, but I find it to be an invaluable document - I have it on shortcut from my taskbar and consult it often.

The typical way to add content is also rather static -- add it to the WAR and redeploy. That's not particularly dynamic tho, and doesn't really facilitate changing content from the web app. One of the things I'd like to be able to create on the fly are JSPs that are then served by the container. Now, Kenneth Jensen may have answered my question for me by providing this snippet: ServletContext context = getServletConfig().getServletContext(); String slash = System.getProperty(file.separator); keystore = context.getRealPath(/) + WEB-INF + slash + getInitParameter(keystorefile); The key being the getRealPath(/) code. So, my question is do you think that it's reasonable and fairly portable to leverage that technique to find where on the system a webapp is deployed and use that as a base path to create new resources to be served by the container? I'm aware that it is possible for a web app to be deployed in an unexploded WAR, and I would simply make it a precondition that this not be the case (and for 99% of most systems, it simply isn't an issue).

RE: Question: Steve Kirk
Thanks for saying that LOL :) but I'm afraid that you flatter me ;-) I've been using TC on and off for about 4 years, I have a working knowledge of the features that I actually use in my webapps, and answer Qs on those when I can, but that really is about it - there are many others on this list who are far more knowledgeable than I am about TC. Perhaps I'm talking too much at the moment and the volume is giving a false impression of quality ;) I did read your post, but unfortunately precomp JSPs are not something I use, I'm just aware of what the general benefits are, as I've worked on a project where someone else set up the precomp code for our production environment. It's on the list of things I want to learn about next, because it is good practice for production servers, and I have to set one up very soon. However I bet that someone will be along soon who can help you. I have no role in the project - I am just another web developer, the same as most people on the list. I am quite active at the moment, mainly because I just rejoined after a few months' absence, and I've just done upgrades to the latest versions of JDK/TC/NetBeans, so have read a lot of docs, and received help from list members, so have some fairly current knowledge to share. When on the list, and I have a few mins to spare, I try to help people if I know anything relevant.

RE: Adding content/JSPs on the fly
OK glad you've got that off yr chest ;) I can sort of see yr point, but these are not issues that have troubled me personally. I tend to look at TC from the point of view of I'm just pleased that someone else wrote TC for me for free and it works v well at what it is designed for. Every product has limitations, and can't cover every feature that we would all like, and I find it amazing that TC has so few limitations given that it is produced on the backs of volunteer contributions. I'd rather have one TC that 2 IIS's ;) If you're serious about pursuing a solution for this, Maybe there's an alternative, how about this. (It's not pretty but saves some of the reinvention that you describe). Let's say it's an acceptable limitatio to create all your new JSPs to a separate webapp folder. This webapp only has a single servlet initially, which is a type of Invoker that you write yourself, eg /dynamicWebApp/JspInvoker, which could be mapped to serve all request URIs of the form /dynamicWebApp/*.jsp Now, when /dynamicWebApp/dnynamicFile.jsp is invoked, the JspInvoker looks to see if a JSP called dynamicFile.jsp exists under that special folder. If it does, then your code translates/compiles/instantiates it (if not done already) and the request is forwarded to it's doPost method. I'm not saying this is easy, but it could be done. You'd be reinventing the classloading and service methods rather than all the other stuff. You might be forced to use SingleSignOn depending on your app, which could be a negative. Perhaps my answer is worse than yours ;) If its any consolation, one of the annoyances I have encountered in the last few months is that I have a particular webapp feature that I can't code well because Java does not provide multiple inheritance. I've done it, but the code is ugly. I've tried 99 ways of doing it different but don't have a better one. However, I realise that full multiple inheritance was deliberately excluded from Java for specific reasons, so I have to decide whether to stop using Java or accept it as good at what it is designed for. And that's an easy choice to make :) -Original Message- From: Will Hartung [mailto:[EMAIL PROTECTED] Sent: Friday 27 May 2005 20:38 To: Tomcat Users List Subject: Re: Adding content/JSPs on the fly From: Steve Kirk [EMAIL PROTECTED] Sent: Friday, May 27, 2005 11:44 AM It sounds reasonable, but probably isn't tested or by design, so probably best to just have a go.

One of the notable bits about it is simply the fact that within the spec, you're pretty much not guaranteed writeable access to the file system at all (save for a temporary area, and it's simply that -- temporary). But the reality is that most engines give you access to the disk that way. Just one more specific point on your note Will - I would have thought if anything that you want it to be a precondition that the webapp NOT be deployed as a war. I've a feeling that if TC explodes the war, then it might not check the exploded FS for changes. Don't take this as gospel though, this is a hazy half-remembered bit of info. As far as I know, the Servlet spec doesn't have a deployment method outside of a WAR. It's pretty much a container behavior to actually explode the WAR on to the file system, yet, most obviously do for performance reasons. But it does bring up a basic problem, for example, if by some fluke the app is redeployed, all of that new data is blasted away by the WAR..that would be Bad. But I can't see another (easy) way to create JSPs on the fly, or in fact to create any other content that can be served directly the server. It's an annoying nit of the spec, to me, that it doesn't expose this behavior to the developer. For example, unlike EJBs (which has a specified limitation on accessing the disk), the Servlet spec does allow you to access the disk, though perhaps not within the WAR hierarchy. But, there is no way to, say, forward to a static resource that the server can

It's not exactly trivial or elegant, and having to switch on SingleSignOn might be a problem in some apps, but could it work?

RE: Tomcat/Personal Web Server Problem
Looks like TC cannot start. If you have fresh installed it, then hazarding a guess, I'd say it might be because the port might be in use. You can't have 2 servers on the same port. Did you have them configured to run on the same port (8080)? One thing to check is to open a dos window then type netstat -a, this will list all ports in use on your machine. Give it a while to run, this can sometimes take up to a minute depending on what's running on your machine.

The main problem which could arise is if tomcat 5.0.x uses a java class or method which disappeared on jvm1.5 This would be doc'd in 1.5 release notes, didn't notice anything relevant when I upgraded: http://java.sun.com/j2se/1.5.0/compatibility.html Also, why would the TC team release a compatibility package for 5.5 on 1.4 if they thought it wouldn't run anyway?

RE: [OT] RE: DNS Request distribution and TCP NAT distribution For Tomcat Cluster
Thanks Peter, interesting. Your experience of it sounds similar to other experiences I've had when changing from one ISP to another (there seems to be a cutover time of up to 3 days where some 3rd party ISPs clearly still cached and served the old IP for our domain name). It was because of this that I investigated more at the time, but as you say, it's each ISP to their own practice. I would expect any DNS server run by an ISP (such as AOL) to receive the zone records from SOA intact, i.e. these major dns servers should know about all rr Ips for a given dns name, and would therefore be able to RR distribute them to lower-tier DNS servers. Your expectation is incorrect, I think - even the large DNS servers make standard requests for A records for the given FQDN, and cache the result. Yes you're probably right there now I think about it. I think these are referred to as caching servers as opposed to secondary. It's the secondaries that receive the zone transfers. Having said that, I'd have thought that a large ISP such as AOL would have secondaries, (inaccesible by joe public), but would also have caching servers, which are the ones they make public. Since they typically have several caching DNS servers, in theory there is a good chance that each of them will get a different one of the RR Ips from their secondary server, so in theory the RR goal is often achieved? For example I just used DOS nslookup to query my ISPs 2 main dns servers for www.microsoft.com - they each returned a different address, although repeatedly querying each one returns the same answer every time. If I go through a local caching DNS on my LAN, that returns a third address for MS - again, the same one every time. If the result contains a set of IP addresses in a particular order, then that's what is obtained. To my knowledge (my reasoning falls down if this is not the case, so this is the bit to check!) neither the returned A records themselves nor the returned SOA record contain any indication that they should be handed out in a round-robin fashion; and the SOA record would not typically be requested by another server. AFAIK that is correct, the DNS protocol does not say anything about how DNS servers should respond to clients when there are multiple Ips registered in DNS for a host. Likewise if the DNS server only returns one IP all the time, the client protocol provides no way for the client to say give me the next one or give me number 3 or give me them all. So some caching DNS servers will always return the first one in the list, others will order Ips according to their own rule (which meets the spec) but then always serve the first one in that order. And others will cycle through them in turn (which is RR). Basically, it's internal feature of the DNS server to decide how it treats hostnames for which is has more than one IP. Of these 3 basic approaches, the first gives no RR, the second is slightly better, the 3rd is the best. Of course they are all only rudimentary load balancing methods, and of course even the 3rd falls down if ISPs with millions of users happen to cache a single IP for a site, as you say. Someone please correct me if any of this is wrong, as I'd like to understand this area better :) PS this has rekindled my interest so I just googled to refresh my mind on the basics, this seems a useful page that explains what we are talking about above. http://www.onjava.com/pub/a/onjava/2001/09/26/load.html - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I was not looking forward to reconfiguring logging, as it'd always been an area that generated some confusion, but if anything logging is easier on 5.5 than 5.0 IMHO. I had Loggers configured in 5.0, but these are redundant in 5.5, so I have no logging config at all now - I just use the java.util.logging classes in my servlet code (no changes at all since it ran on 5.0), and it works perfectly for my needs without any config file at all. -Original Message- From: Tim Diggins [mailto:[EMAIL PROTECTED] Sent: Thursday 26 May 2005 10:28 To: Tomcat Users List Subject: Re: Are we required to move to Tomcat 5.5 in order to move to JDK 1.5 I'm not an expert, but I believe (from experience previous googling) that tomcat 5.0.x will respond with an exception (IncorrectClassFileFormat or something) when it encounters class files compiled with jdk1.5, and that thus yes you need 5.5.

RE: [OT] RE: DNS Request distribution and TCP NAT distribution For Tomcat Cluster
Yup. So anyone using your ISP's DNS servers will get one of two IPs for www.microsoft.com at present, out of the however many they have. Lumpy load balancing in action :-). Yes true, hadn't thought of it like that. Where a site has more Ips for a host than an ISP has DNS servers, this is going to lead to lumpiness. I guess this is one of the key reasons why RR DNS is only ever a poor man's load balancer. OK-ish if you have 2 Ips, gets worse if you have more. You likely haven't set up your own caching DNS to forward requests to your ISP's DNS servers; otherwise you'd have had one of the same answers. Funnily enough I have, and I use Demon too. I think my local DNS has maybe kept an MS entry cached and it's refresh TTL is out of sync with the demon DNS caches. But what you say is right - if I restart that local DNS, it will then get a fresh MS entry from one of the 2 cached at the Demon servers. In fact I just have, and it did. Thanks again, that's clarified a few things I was a bit fuzzy on.

Logging to two logfiles by classes instantiated by init
I have always used 2 ways of logging. Mainly I use java.util.logging classes, including a custom Formatter that I wrote myself. I do not use log4j. When my webapp first starts, the init() method of my own custom Invoker servlet loads the config for my main logging code is loaded from web.xml using getInitParameter(), so if for any reason that config is bad, or some other exception happens during init(), I use the bogstandard javax.servlet.GenericServlet#log() method to log any problems to TC's own loggers. All of this works fine. Once initialised, my main logging code works by providing a static method that any servlet in the webapp inherits. Now, here is the weird thing. When Invoker.writeToLog is called by a class that was instantiated during Invoker#init(), it writes the log message to both its own logfile and the TC stdout log. These two files have quite different formatters, and the message appears in the appropriate format in each file. When double-logging happens, the TC log clearly shows that Invoker.writeToLog was the calling method, so it's not just that my code is calling both methods. Servlets and classes loaded/instantiated later log correctly to my main log only. Can anyone suggest what might be causing this please? More details on setup below. I have been running TC5.0.x on JDK1.4.x for about a year, and previous versions before that. I just upgraded to TC5.5.9/jdk1.5.0_02. Have made the config changes required and it all works swimmingly. Only one problem persists, a small logging issue, which in fact was there before, but I ignored it. Basically some of my log statements get written to two files at the same time. However, given that logging has moved on a bit in 5.5, this is a chance to clean things up, so I have decided to take a look at it. I have removed the Logger that used to be in conf/server.xml in TC5.0. I therefore have the bogstandard logging that ships in a standard 5.5 TC install. (I do have a FastCommonAccessLogValve and a RequestDumperValve configured but I'm assuming that those are separate issues). - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Tomcat/Personal Web Server Problem
Well based on your netstat output below, this proves that something is listening on 8080 and 8081. It doesn't indicate what is (not sure if there is a way to find out). If you are accessing http://localhost:8080 and still getting PWS, then it is still starting on 8080, before TC is, so TC is probably failing to start. If TC cannot start for this reasons, it will say so in its logs - look at any files under the logs directory under your tomcat install directory. Read carefully for any error logged. I realise that you have repeated that PWS is uninstalled, but you do also say that you can still access it at 8080. Perhaps it would help if you said why you think you are accessing PWS not TC.

You could implement a filter that checked the time since last visit, and if the session had expired according to your custom rule, invalidate the session and redirect to appropriate page such as login. You'd have to make sure that the default session time set in server.xml was longer than the max session time you wanted in your custom method, otherwise the browser would time out the session for you if based on cookies.

RE: log files with servlets ?
For how to set up logging of your Java servlet code on 5.0.28, you need to add a Logger to your conf/server.xml file, inserting it inside your Host.../Host or Engine.../Engine tags will probably get you going. To get apache-httpd type logging going, you need a Valve, again insert it within your Engine or Host tags, looks a bit like this: Valve className=org.apache.catalina.valves.FastCommonAccessLogValve directory=logs prefix=access_log_ suffix=.log pattern=common resolveHosts=false/ Do you have doPost method() implemented in your servlet class?

RE: How to create user thread in tomcat
Write your thread class (myThreadClass) as implementing Runnable. Write a class that implements ServletContextListener and config it in web.xml like this: listener listener-classmypackage.MyScListenerClass/listener-class /listener Now have your ServletContextListener start a new thread using your Runnable class in its contextInitialized method, which is called when the app starts. You might want to consider what happens if/when the run() method of your myThreadClass returns. Do you want to restart the thread again or not? If yes, you might need to put it in a while loop within run() - if this is of the type while(true) until it throws an exception, make sure that you catch the Exception gracefully, and also include code like this in the innermost part of the loop so that it is well-behaved about sharing resources with other threads on the machine: Thread.currentThread().sleep(1000 * delayMilliseconds); You might also think about what needs to be done to gracefully exit from the thread when TC shuts down. This will influence whether you make the thread daemon or not, and whether you need inter-thread communication so that your main webapp can tell your non-daemon thread to exit gracefully ASAP. Have used this approach before, and am about to use same approach again on another project. It works. You *do* need to take care about being threadsafe. If you don't understand how to do that, then you need to read up on it - it's beyond the scope of a single email.

RE: Performing an action on form-based login
Not maybe of direct help unless you get really stuck, but my approach was to use TCs sessions, but not its authentication framework. My original reasoning for this was that I wanted login details to be in a RDMS table along with other data. So I coded the login/logout process myself, which was a little work to achieve, but gives me freedom to handle the sorts of things you are talking about in a flexible way. My way around the problem you describe is that when someone successfully authenticates, I add their uid to the session object as a String in the doGet() method: String uid = request.getParameter(form_uid_field); request.getSession(true).setAttribute(uid, null); And because the uid is now accessible via the session object, when your SessionListener catches the attributeAdded/Changed/Replaced events, they pass a HttpSessionBindingEvent, from which you can call .getSession().getAttribute(uid) -Original Message- From: Ross Nicoll [mailto:[EMAIL PROTECTED] Sent: Tuesday 24 May 2005 15:17 To: Tomcat Users List Subject: Re: Performing an action on form-based login We're having more or less the same problem.

RE: DNS Request distribution and TCP NAT distribution For Tomcat Cluster
Peter, I agree that DNS is a very lumpy way of doing load balancing. But your comments interested me. Can I ask how sure you felt of what you say here please: No standard way afaik. Worse, downstream DNS servers may (often do) cache the returned IPs for up to a day despite any cache expiry you put on them. If (say) the AOL DNS servers all get the same IP address in their cache, all your AOL visitors will visit the same IP address. I'm not for a minute suggesting that it is wrong :) and wouldn't dream of doing so, because I don't know all the facts myself. I tried to research it but could not get to the bottom of it with any real info from ISPs (the problem is that they seem to do their own thing to various extents). I'm just interested in comparing experiences/opinions. I have set up roundrobin DNS for an ecommerce site in the past without any complaints from users, and the balance of load between a pair of clustered servers seemed pretty even. I would expect any DNS server run by an ISP (such as AOL) to receive the zone records from SOA intact, i.e. these major dns servers should know about all rr Ips for a given dns name, and would therefore be able to RR distribute them to lower-tier DNS servers. I would have thought that the level at which DNS servers do not pick up the fact that there is a RR DNS entry is where they do not do a zone transfer from a primary DNS server - they simply act as a client and cache what they get as a response, so they are unaware that there even are more than one IP. I'm speculating that these minor DNS servers belong to small ISPs, or private companies running their own DNS in-house? So overall I guess I'm saying I'd be surprised if AOL's DNS servers only cached one entry of a RR set for a DNS name. What are your thoughts? -Original Message- From: Peter Crowther [mailto:[EMAIL PROTECTED] Sent: Wednesday 25 May 2005 17:15 To: Tomcat Users List; [EMAIL PROTECTED] Subject: RE: DNS Request distribution and TCP NAT distribution For Tomcat Cluster From: John MccLain [mailto:[EMAIL PROTECTED] 1) for DNS Request Distribution - I dont understand. The browser sends a URL to the DNS, the DNS responds back with an IP address. But what if at that IP address, you have a web server listening on port 80? The browser talks to that Web server. If Tomcat is at that address also, Tomcat would have to listen on another port. Can the DNS distribute back to the browser the IP Address AND the Tomcat port so the browser connects to Tomcat on a non port 80 port? Only if your original URL uses the name:port notation - there is nothing in this scheme to prevent that. Also, is there a way to setup the DNS to Round Robin or check server load on the servers in the Tomcat cluster so it knows which Tomcat server ip:port to send back. No standard way afaik. Worse, downstream DNS servers may (often do) cache the returned IPs for up to a day despite any cache expiry you put on them. If (say) the AOL DNS servers all get the same IP address in their cache, all your AOL visitors will visit the same IP address. DNS is a very lumpy way of doing load balancing. OR does this whole thing imply that you have an IP for each web server (IIS) IP address yes; IIS depends on whether you want IIS or Tomcat at the business end of the cluster. and each web server is tied to each server in the Tomcat cluster via a jk2 redirector? If you wish to use that architecture, yes. 2)TCP NAT distribution - Does this mean that when the browser connects to the IP address, that that connection is intercepted and the request is distributed to a server in the Tomcat cluster? Yes. If this is the case, then what does the interception? Generically, a router that has this capability. It's that router that also does the NATing. Many mid- to high-end hardware routers and some software routing packages can do this. and how do you configure that thing to use a specific algorithm (server load, Round Robin, etc..) to choose which server to forward the request to? That is router-specific. There is no standard (afaik) for the servers to return load information, so you're stuck with proprietary solutions *or* the router doesn't load-balance. can it forward to an IP:PORT or does it have to forward to an IP That is router-specific. Given that the capability typically exists on mid- to high-end routers, most will also have the capability to change the internal port that is in use. - Peter - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Compiling JSP files
Is there a reason why you can't let TC compile the JSP on demand and read
the log output? Works for me.
Failing that, I suspect your cmd-line classpath has some errors.
What does echo %classpath% produce?
And are you sure these are right in your classpath (from your previous post
below):
C:\tomcat\work\Catalina\Site1\_
C:\tomcat\common\lib\servlet
Not sure what the first one is, and the second should read servlet-api.jar
not servlet.
You also need to add C:\tomcat\common\lib\jsp-api.jar to the classpath too
if you haven't already.
Also you should have all classes in the classpath that your class itself
imports - either explicitly include the full path to each class separately
(drop the .class extension), or a folder containing the class hierarchy in
folders, or the full path to one or more jars that include the classes.

what you can do is to use an ant task for do the precompilation.
This is a bit smarter than via the command line I guess.
The docu is under
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jasper-howto.h
tml#Web%20Appl
ication%20Compilation
It's not very well documented, it took me a while to finally
get it working, but it's working fine for me now.
So if you want to give it a try, I can give you some further
assistance, if needed.
Cheers
Bernhard

Betreff: Compiling JSP files
I am having a problem where one of my jsp files won't
compile. Tomcat
successfully creates the java file but it never creates the
class file
and hence never responds to the request for the page.
I am looking for what needs to be in the command line in order to
manually compile the java file the gets created in order to
look for
errors in that process.
This is what I have so far but I am getting errors.
c:\jdk1.5.0\bin\javac -classpath
%CLASSPATH%;C:\tomcat\work\Catalina\Site1\_;C:\tomcat\common\l
ib\servlet
.jar test_jsp.java
Errors:
test_jsp.java:5: package javax.servlet.jsp does not exist import
javax.servlet.jsp.*; ^
test_jsp.java:8: package org.apache.jasper.runtime does not exist

RE: Validation Frame work
David is right, JS and serverside validation perform different roles. To expand on his comment a bit more, remember that the requests that your webapp receives could be sent by any HTTP client, not necessarily by a friendly web browser. If someone were so inclined, they could write their own HTTP client to interact with your webapp, that aimed to deliberately submit bad data to your servlet, in which case your JS validation would have been bypassed. What they can't do is bypass your serverside validation (or at least this is much harder). Just one trick that such nasty people might try is to insert JS code in any form fields that you let them create or edit. If this field data is then displayed in other pages of your app, this might cause anyone viewing that page on your site to download a trojan/virus/etc. It's really very easy to do. And this is only one such exploit. There are many others. -Original Message- From: David Smith [mailto:[EMAIL PROTECTED] Sent: Tuesday 24 May 2005 16:19 To: Tomcat Users List Subject: Re: Validation Frame work Because you should never trust the client. They may not be submitting from your form. Javascript is just a nicety to save the user a whole request/response cycle just to find out a field is missing or wrong.

RE: Minimal server
Thanks Will - I had not heard of embedded TC before. Interesting, and a nice piece of innovation too. Hence why I misunderstood the thread earlier (sorry). This could be very useful. If I've understood correctly, I can somehow bundle together my existing TC webapp along with the tc-embedded code, compile a jar that contains them both, and distribute that as a complete system, and when the user double-clicks, it runs a very lightweight version of tc, running my webapp only, in the user's browser? If so that will be a great way to distribute a TC webapp for testing, because as long as you don't have too many testers, this saves having to set up a separate test server. -Original Message- From: Will Hartung [mailto:[EMAIL PROTECTED] Sent: Tuesday 24 May 2005 17:38 To: Tomcat Users List Subject: Re: Minimal server From: Steve Kirk [EMAIL PROTECTED] Sent: Tuesday, May 24, 2005 5:02 AM I don't see how you will do that without installing some kind of dynamic webserver on each PC, whether that be apache-hpptd, tomcat, or other, plus the web application (which needn't be servlets, it could be perl based). And if you are going to do that, what's wrong with installing tomcat? If the goal is to write an, essentially, stand alone application that just happens to be browser based, then you don't want to install tomcat per se, rather you just want to have an HTTP based core around which you can wrap your application. Its not designed to be a general purpose application/webserver, rather a very application specific server. It also allow the application to be distrubted as either a simple, complete Jar file, or perhaps wrapped in a .exe. When the user clicks on the icon, the application launches a browser to the applications home page. Now, if he just wants to distribute a WAR, as a central service for several users, then, yes, its easier to have the client simply install tomcat (or bundle it in their installer), and deploy the war. But for a client side, browser based application, embedding can very quite viable.

RE: redeploy of webapp loses GlobalNamingResource DataSource
From the look of the stacktrace, which mentions org.postgresql.Driver.parseURL as the point where the initial exception was thrown, maybe the URL attribute in your Context's Resource or ResourceParams might either contain a wrong value or a typo. This might be leading to a parsing exception, even though the trace doesn't say so explicitly. My experience is that the exceptions in these cases do not always give you a very precise clue as to the problem. For example, very recently on 5.5.9, I was getting a similar problem to you, where just because I had a leading space in the url attribute value, the whole DBCP resource was rejected, with the exception messages Cannot create JDBC driver of class '' for connect URL 'null' caused by no suitable driver.

RE: problem: Session invalidation in the servlet accessed via foreign context
OK. So... your conclusion is that you can't do that, right? That's what I'm reading the servlet 2.4 spec as saying, because you can't invalidate a session in one context that is not accessible to you in another context, irrespective of whether you use getRequestDispatcher to do that.

RE: problem: Session invalidation in the servlet accessed via foreign context
OK no problem, I'm learning something here too :) I agree, one app cannot access a session created by another app (unless you set singlesignon, which we'll ignore for now). I am referring just to the single line I quoted earlier, from SRV.7.3 of 2.4 spec. I'm reading that as saying that if app A creates session X for user U, then the user U then accesses app B, which then includes a servlet from app A via its RequestDispatcher as you have done in your example, context A will not have access to the session in the second request, even though it created it, because it was routed through app B, which is not allowed to access it. I might have misinterpreted this, because I have no actual experience of it. I can see that it might be possible that the session is invisible to B but not A. If so I'm more than happy to be told I'm wrong by someone who knows? -Original Message- From: Akoulov, Alexandre [IT] [mailto:[EMAIL PROTECTED] Sent: Monday 23 May 2005 10:46 To: Tomcat Users List Subject: RE: problem: Session invalidation in the servlet accessed via foreign context Thanks, Steve, again.

RE: Tomcat For SSL
Get ready for differing opinions on this, it's been asked loads of times before, try searching the archives for more info. My very quick summary would be that you do not need apache httpd to do SSL, and it can be very fast and stable without apache, as well as simpler to config if you don't already know apache, but there are good reasons to introduce apache. depending on the exact requirements of your site, there are some useful feature benefits from using apache+tomcat, and when the site gets heavily loaded, apache+tc performs better than tc alone, if you let apache handle the static page requests. A friend of mine advises me that he uses apache+tc for these reasons: - server side includes which is easier for most people to use to do minor dynamic content in otherwise static pages - mod_rewrite can help with redirection between http - https if you have pages that can only be accessed through one or other protocol - can config reverse proxy content off another server I do not run apache with my TC because I do not require any of these features; however I am not against using it for the right app. -Original Message- From: Scott Purcell [mailto:[EMAIL PROTECTED] Sent: Monday 23 May 2005 14:39 To: tomcat-user@jakarta.apache.org Subject: Tomcat For SSL Hello, I have a webapp that is running on Tomcat 5.5.

RE: DBCP
DBCP has some config params in the context.xml that will clean up for you if you don't return resources to the pool. It will also test connections for you to make sure they're alive, and close/replace them if not. To config these features, set the params in your Context's DBCP Resource tag, for example: Resource name=jdbc/myDbResource auth=Container type=javax.sql.DataSource maxActive=10 maxIdle=5 maxWait=1 username=ao password=ao driverClassName=com.mysql.jdbc.Driver url=jdbc:mysql://localhost:3306/myWebApp removeAbandoned=true removeAbandonedTimeout=60 logAbandoned=true validationQuery=select 1 testOnBorrow=true testWhileIdle=true timeBetweenEvictionRunsMillis=1 minEvictableIdleTimeMillis=6 / The attributes in question are those from removeAbandoned down. However it is not advised to rely on this as a means of managing your pool - this is your safety net. It's far better to return connections to the pool yourself in the first place. A proper try/catch/finally structure is the way to go, there are numerous examples on the web.

RE: confused about simple logging
Your confusion possibly arises because there are at least 2 types of logger that you might mean, and 3 main choices for one of those at the moment, although one of those 3 is deprecated and a second is probably becoming less popular. OK I'll take a quick stab and see if this gets you anywhere in the right direction. You mention two distinct types of logging. The 1st is the hit logging which is very similar to what you would get from apache httpd. This simply logs each incoming request. This is achieved by adding a Valve to your %catalina_home%\conf\server.xml - you can embed it inside the Host/Host, Engine/Engine or Context/Context tags, but for your purposes, just shove it in the engine for now. It looks a bit like this: Engine blah blah Valve className=org.apache.catalina.valves.FastCommonAccessLogValve directory=logs prefix=ao_access_log_ suffix=.log pattern=common resolveHosts=false/ /Engine You can tweak the path, filename, and the pattern that defines each line - see http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/valve.html for details. Leave resolveHosts set false to speed up performance. Not that my example above is from my own 5.5.9 server - ISTR 5.0 config syntax is different - check the doc link above for the detail. The 2nd part of your logging is where you write your own messages to a logfile. I did that as follows: java.util.logging.Logger logger = java.util.logging.Logger.getLogger(logname); logger.setLevel(logLevel); fh = new FileHandler(logFilePath, maxLogFileSize, logFileCount, true); fh.setFormatter(new AoLogFormatter(logFileDateTimePattern)); logger.addHandler(fh); Then to write a log message you can just do this: log(Write this to the log); and it will write the log file to logFilePath See the java.util.logging.Logger javadocs for more details.

RE: confused about simple logging
Sorry can't help you there. I was where you are now a year or more ago, fancy logging frameworks - too much hassle to learn for the simple logs that I want. But I soon realised that it was more work, and quite a bit more ugly, trying to do your own thing. I'd say bite the bullet and embrace the latest release and logging framework. There have been a few different ones over recent versions, but the TC dev team are converging them nicely now. It might seem a little over engineered for simple logging requirements at first, but once you spend the time to make it work, you will get what you want, and come to realise that the advanced features are really useful for debugging in situations exactly like yours. I'm using commons-logging very successfully, is very flexible and not hard to learn. If you really reach your wits end making logging work and just want a blunt instrument to detect one-off if your overloaded method is called, when not do something else to signal its presence, such as add a line to it which creates a file called ive.been.called in a certain directory. Gets you past having to fix your log/stream problem. You won't find this logging framework in the TC docs though ;) -Original Message- From: Jim Henderson [mailto:[EMAIL PROTECTED] Sent: Monday 23 May 2005 19:58 To: Tomcat Users List Subject: RE: confused about simple logging Well I am having lots of self doubt.

This is achieved by adding a Valve to your %catalina_home%\conf\server.xml - you can embed it inside the Host/Host, Engine/Engine or Context/Context tags, but for your purposes, just shove it in the engine for now. It looks a bit like this: Engine blah blah Valve className=org.apache.catalina.valves.FastCommonAccessLogValve directory=logs prefix=ao_access_log_ suffix=.log pattern=common resolveHosts=false/ /Engine You can tweak the path, filename, and the pattern that defines each line - see http://jakarta.apache.org/tomcat/tomcat-5.0-doc/config/valve.html for details. Leave resolveHosts set false to speed up performance. Not that my example above is from my own 5.5.9 server - ISTR 5.0 config syntax is different - check the doc link above for the detail. The 2nd part of your logging is where you write your own messages to a logfile. I did that as follows: java.util.logging.Logger logger = java.util.logging.Logger.getLogger(logname); logger.setLevel(logLevel); fh = new FileHandler(logFilePath, maxLogFileSize, logFileCount, true); fh.setFormatter(new AoLogFormatter(logFileDateTimePattern)); logger.addHandler(fh); Then to write a log message you can just do this: log(Write this to the log); and it will write the log file to logFilePath See the java.util.logging.Logger javadocs for more details. This is very basic. Much more spophistication can be achieved through config files. -Original Message- From: Lane [mailto:[EMAIL PROTECTED] Sent: Monday 23 May 2005 18:01 To: Tomcat Users List

GB developer, Robert and Tomi, thanks very much for pointing me to these search sites. I was not aware of any of them before, despite having developed on TC for several years.

RE: What happened to the searchable list archive?
Hi Mark, Eyebrowse was the place that I used to rely on for searching, when I was active on the list up until a few months back. When I returned to the list last week, I found that eyebrowse no longer seemed to be in use, hence I checked out the official TC site to see what might now replace it. I started here: http://jakarta.apache.org/tomcat/index.html Then clicked mailing lists towards the bottom of the left hand menu, which took me here: http://jakarta.apache.org/site/mail.html And from there I scrolled down to the Table of Contents section and clicked the Tomcat link near the bottom of the page, which took me here: http://jakarta.apache.org/site/mail2.html#Tomcat Finally, from there I clicked archive under the list of tomcat-user links, which took me here, which is what I think you are calling ASF, and what I was referring to as the official archive: http://mail-archives.apache.org/mod_mbox/jakarta-tomcat-user The page above is fine for browsing archived messages, but I can't see a search link like there used to be on eyebrowse. Clearly you can use google to site-search these archive pages, like you can on any site, but it's a little unwieldy to use, hence why I started this thread. In going through this all again so that I could quote the links above, I now see that Marc's site and mail-archives are both already linked at a high level from the generic apache mail archive page( http://jakarta.apache.org/site/mail.html ), so apologies for not seeing those earlier. However, I didn't spot this the first few times I looked, so I'd still suggest that in the interests of user friendliness, it might be worth linking from the TC pages at http://jakarta.apache.org/tomcat more directly to the search pages that I mentioned in my last post, as well as any others, given that the official archive page does not seem to have its own search. Hope this helps, Steve. -Original Message- From: Mark Thomas [mailto:[EMAIL PROTECTED] Sent: Sunday 22 May 2005 21:18 To: Tomcat Users List Subject: Re: What happened to the searchable list archive?

OK, so now I'm struggling.
So I'm going to take a punt and say that I think there may be some kind of
class loading problem. I say this because:
- I have fresh installed TC, mysql and jdk;
- mysql works from the command line using my datasource username/pw;
- I have checked and rechecked my config a thousand times;
- the mysql driver is in the right folder;
- the error is suggestive of the fact that TC can't find the driver.
However, the driver it is there in the common/lib folder, plain for anyone
to see. I can only assume this is to do with security/classloading. I've
eliminated security, because TC runs as a service under the system account,
and I've checked that this account has read access to the file.
I'm almost tired of looking - if I can't solve it tomorrow, I'll be (very
reluctantly) setting aside TC 5.5 and carrying on with 5.0.28. I don't want
to do that, because 5.0.28 has some sesssion management bugs I'd like to get
past, and also because I've now spent 3 days trying to make 5.5 work.
So, any help would be most gratefully received :)

It definitely does not work in 5.5. I've used the config from

that the

either in ${CATALINA_HOME}/common/lib since it must be

RE: problem: Session invalidation in the servlet accessed via foreign context
I'm not sure why you think there is a problem with invalidation. I'm no
expert, but I'm not sure that I would expect the code below to work, because
by default, servlets must not share sessions between webapps, and you are
asking that a client request to one context is passed to another, and still
the session data is available. Withouht single sign-on, I would have
thought that sessions will not be shared.
I've just flipped through the 2.4 servlet spec. Section SRV.7.3 says
something very specific about your scenario, as follows: if a servlet uses
the RequestDispatcher to call a servlet in another Web application, any
sessions created for and visible to the servlet being called must be
different from those visible to the calling servlet.
I appreciate that you are also saying that v3/v4 behaved differently - but
are you sure that the config of those versions was not different, perhaps
they were configured to share sessions (single sign-on)? I'm not sure on
the detail of earlier versions of the servlet spec, but perhaps session
behaviour was defined differently in previous versions. You could find out
with a google search, or maybe someone else will answer

Thanks a lot, Steve, for your reply.
No, I am not using SingleSignOn neither hoping to share the
same session across contexts.
The only thing I was testing is that I could invalidate and
then create a new session in different scenarios.
I ran the test with the java debugger and could observe that
when invalidating/creating a session in ForeignContextServlet
it in fact did not create a new session and left us with the
reference to old (ie invalidated) session after line No.3.
My next step is start looking into the tomcat source code to
try to work out what's happening. Do you think it's best way
to approach this issue?

I'm not sure I fully understand this issue, but seeing as
no-one else seems
to have replied yet, maybe a few Qs might help you work through it:
Are you hoping that both contexts will share their sessions?
Are you using the SingleSignOn feature in server.xml?
When you say that ForeignContextServlet does not create a new session
object, are you explicitly testing that within
ForeignContextServlet itself,
or from a servlet in another context (e.g. DebuggerServlet)? i.e. is
null==session after step 3?
You say that the session is invalid/null after line 2, but
have you tested
that it was valid/non-null before line 2?

Subject: problem: Session invalidation in the servlet accessed via
foreign context
Hi all,
It seems that there is a problem with session invalidation in
tomcat5.0. Please refer to the explanation below:
1. HttpSession session = req.getSession(true); // get
existing user session or create one if does not exist
2. session.invalidate(); // invalidate user session
3. session = req.getSession(true); // create a new session (
ie a valid session)
The above three lines of code are commonly used to invalidate
the user session and then create a new one. Tomcat implements
this behaviour by creating a new session object in line No.3.
However, in tomcat5.0 implementation (5.0.28) when the above
code is accessed via foreign context it does not create a new
session object and therefore a session is still invalid after
lineNo.3 is executed. The following code demonstrates the
problem:
// servlet that runs in the same tomcat instance but in a
different context to DebuggerServlet's context
public class ForeignContextServlet extends HttpServlet {
public void doGet(HttpServletRequest req,
HttpServletResponse res)
throws ServletException, IOException {
HttpSession session
RE: Mysterious failures
What is your actual logging config? Hazy memory, but don't you want debug=99 rather than debug=1 to get more detail? If you really can't get logging to work, you could insert System.out.println(blah) statements at key points around where you think the crash might be caused, in lieu of your log statements. Not pretty but it can get you results. Some Qs to narrow it down a bit: Is the crash triggered by a single type of request, or maybe a burst of traffic, or will it crash even with no requests? Is the crashing request direct to TC or via apache httpd? Is a TC html error page generated, what does it say? Do you start any of your own threads? Does your code always return pooled objects to the pool? Is there some app that people use to make sure the server stays up by checking it every so often and restarting if needed?

DBCP datasource works on 5.0.28 but fails on 5.5.9
I know that DBCP is a common problem discussed on this list - I have been helped, and have helped other people, with it before. So before posting this message, I have recently re-read the 5.5 release notes and 5.0/5.5 DBCP/JNDI how-to docs and checked the list archives. But can't find a solution to my current problem. Until recently I had a working webapp running on tomcat 5.0.28 with connector/j 3.1.7 and mysql 4.1.11-nt, all on windows XP and jdk1.4.2_08. The app uses container-managed commons DBCP for all its database access. The DBCP resource config has been set up and working unchanged for a long time on various builds of TC 5.0. I have it set up like this: ResourceParams defined in context.xml, in war file's META-INF folder resource-ref declared in web.xml in war file's WEB-INF folder The connector/j jar file is in tomcat's /common/lib folder name of JNDI resource matches in ResourceParams, resource-ref and Java source code. This all works on TC5.0.28 / JDK1.4.2_08. However, I am attempting to upgrade to TC 5.5.9 / JDK1.5.0_02. I did a fresh install of both of these to standard directories, recompiled the webapp for jdk1.5, and deployed it with the same config files and setup above from TC 5.0.28. However the webapp now reports an error when requesting a connection from the pool, see stacktrace below (from the TC stdout logfile under TC logs directory). I tried changing my context.xml so that the params are all pairs of name=value within a single Resource/ tag, as now seems to be preferred in the 5.5 DBCP how-to, rather than my original nested set of tags under ResourceParams, which was the approach used in the 5.0 equivalent how-to. But still no joy. I also tried upgrading to connector/j 3.1.8, no joy there either. When TC starts up, the webapp deploys OK from its war file, and the context.xml is copied to the /conf/[engine]/[host]/ folder OK, without any parsing errors logged. The connection pool initially seems to work, in the sense that this code executes OK: Context ctx = new InitialContext(); String resourceString = java:comp/env/jdbc/ + config.getString(ConfigConstants.JNDI_DATABASE_RESOURCE_NAME); DataSource pool = (DataSource)ctx.lookup(resourceString); However, an Exception is thrown the first time that I do this: Connection conn = pool.getConnection(); I'm stumped after hours working on this. I've read through all the docs, how-tos, and release notes that I can find, and searched the mail list archives on mysql and tomcat sites, as well as googling various searches. Has anyone had this problem themselves or have any insight to offer please?

If so then I've missed some docs somewhere, maybe there is other new stuff that I haven't seen. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

tomcat System Administrator's Guide and SysAdmin tools
All, We have been looking for a comprehensive System Administrator's Guide for Tomcat, that looks at Tomcat from the perspective of a System Administrator that needs to deploy tomcat and applications on tomcat. Most of what we have googled concentrates on deploying tomcat for a developer, or a development environment. Many SysAdmins don't actually speak java, though, and would be looking for a guide to be able to support java applications on their servers without having to become java experts themselves. We are also looking for any tools that might be used to verify a successful installation of tomcat, beyond the index.jsp, and manager and admin tools. Has anyone written anything that goes through and makes sure that tomcat is installed correctly, and that everything is set up properly, as an installation verification tool? For both the documentation, and the tools, if we can't find anything that I think fully addresses this need, we will take a stab at producing both. Does anyone have any thoughts / suggestions / requests, etc... for such documentation and tools to include? Also, do people think that there might be a place within the tomcat documentation and distribution for these, or should we just target making them available on our own site? Thanks for your help. -Steve J -- Steve Jacobson Support Manager SourceLabs, Inc.

Re: Serving files using tomcat
Ok thanks,
Well I have worked it out,
it turns out I needed the header
response.setHeader(Content-disposition,attachment;
filename=\report.pdf\);
added, this made it work.
So now the problem id that Internet Explorer flashes up the Open, Save,
Cance dialog box twice. Once the second one flashes up the first dissapears
so I am not too concerned. But wondering if this is a quirk, or have I done
something wrong.
My code is now
fis = new FileInputStream(rf.getPdf());
response.setContentType(application/pdf);
response.setContentLength(FileUtils.countBytes(rf.getPdf())); // may
be overkill thought it may be misreporting the file length.
response.setHeader(Content-disposition,attachment;
filename=\report.pdf\);
dos = response.getOutputStream();
int read = -1;
byte[] bytes = new byte[10];
while((read = fis.read(bytes)) != -1)
dos.write(bytes, 0, read);
dos.flush();
return null;

May not be critical but try using the ServletOutputStream instead of
OutputStream.
DOC URL:
http://java.sun.com/j2ee/1.4/docs/api/javax/servlet/ServletResponse.html
//Clear content of the underlying buffer in the response
//without clearing headers or status code.
response.resetBuffer();
response.setContentLength(output.length);
//Returns a ServletOutputStream suitable for writing binary data in the

//The servlet container does not encode the binary data.
ServletOutputStream os = response.getOutputStream();
os.write(output);
os.close();
Additionally, append pdf=.pdf\ to the URL.

I use this code and it works in my app. Their are small differences between
how we copy the data to the response output. I don't know for sure, but this
may account for why the fragment I posted works.
The difference is small, I think it would be worth giving it a try.

Serving files using tomcat
Hi, I have been looking around and haven't found a solution that works basically I have a PDF that gets created dynamically. Now to save memory I have the PDF written to a file rather than a ByteArray. The only way I can be sure that I wont encounter errors creating the file is to use File.createTempFile. The creation goes of ok. And I have checked the file itself and the PDF looks great. How do i now serve this to the user who has requested it. If I try to write it to the response (using the same method I use to creare dynamic image, this works), it just shows up a blank screen. The problem also is, even if it did show the PDF, acrobat, to my understand will read only chunks of the stream and will go pack to get more. Thisis a problem because there is nothing to go back for. So the point, If I can just redirect the browser to a file in the tomcat temp directory (can I do that, will the use have access to that directory), then how do I translate the location of the temp directory to a url that is accesible outside. If not then what other suggestions can people give me. Thanks in advance Steve

Re: Serving files using tomcat

I assume StreamCopier.copy() just does what my code does. I cannot find it
in any of the standard jars, so I assume this is one of your own.
Other than that everything else seems to be fine.
