Re: Tomcat memory-leak problem
I too have been having some problems with Tomcat + memory. I put it down to me running win98 and win98 not properly being able to address memory over 128MB. I normally have dreamweaver, netbeans and tomcat running, and reguarly run out of memory (I have 384MB Ram). I haven't noticed any similar problems running tomcat on linux (with a lower spec machine). Windows does have memory management issues however, and it might be the way tomcat threads means it causes problems with memory on win32 platforms. I downloaded Tweakall in the end, as this comes with a niffty utility which can free leaked memory. sam - Original Message - From: BJ To: [EMAIL PROTECTED] Sent: Wednesday, July 11, 2001 9:50 AM Subject: Tomcat memory-leak problem Hi!

Re: Remote logging?
You might want to consider using log4j (another jakarta project).

List traffic et al
Given the huge amount of traffic this list generates, I can rarely get involved with the discussions that take place. It occurs to me that there sems to be three major discussion themes on the list as a whole: 1.) General servlet/jsp development issues and how tomcat affects them 2.) General tomcat configuration issues 3.) Webserver integration issues I guess as documentation improves (e.g. tomcat book, work by people like Mike Slinn) points 23 will become less of an issue. I'm just wondering if there is any millage in perhaps splitting the list into 2 or 3 lists? Personally, I've got no issues with getting tomcat up and running and so don't care too much about that end of things, however the servlet/jsp development issues is more interesting to me. I don't have too strong an opinion on it, its just that I worry I'm missing some interesting topics because I don't have the time to work though all the posts sam

Emir wrote: List is tomcat-user and not java-server-development; thus, issues such as getting Tomcat up and running (i.e. Tomcat configuration) ARE the purpose of this list. Methinks you should get invovled into discussion more often, given as you say that getting Tomcat up and running is no issue to you: could you perchance share your knowledge with us? The lists are there to provide convenient ways of GIVING to the community, not only TAKING... My 2 cents. snip I have no problem with giving to the community - its just that I've got tired of answering the same questions again and again, and if I answered every question that I had an answer for I wouldn't get any work done (like most/all of us here I do have a full time job). Because I saw the same questions coming up again and again I decided to get involved with the tomcat-book project (which has had to take a back-burner for me at the moment due to things going mental at work). The fact remains that general discussion as to servlet development DOES take place here, which leads me to believe that there may be a place for a decent developmnet mailing list. Now this (jakarta) might not be the best place to host it I'd admit, and if anyone knows of a decent list which already exists that covers servlet/jsp/taglib development, please let me know. On a related note I know for a fact that the jakarta-taglib list contains probably 50% general taglib discussion as opposed to specific stuff about the jakarta taglibs. As to the general config issues for tomcat, there still might be some scope for splitting the list - perhaps one for general issues, and one covering integration with other tools (webservers, EJB containers etc). Its just that given the volume of traffic I think the things that interest me (and the things I could mostly helpfully contribute to) are getting lost. Also the generla configuration issues are typically for the newer users, whilst more advanced issues (SSL, working with IIS/Apache etc) concern those people who are more familiar with Tomcat. By splitting the list, you would reduce traffic for those people only intersted in one side of it or the other, and those that still care about both will recieve the same number of posts (bar some potential cross-posting). This would reduce the amount of people (probably with something to say) who leave the list because of the amount of daily posts.. sam

Re: List traffic et al
I think tomcat is a really good product, but for me it did take time to figure out how the various config files, and their (initially) unwieldy syntax works. I no longer consider the tomcat configuration syntax unwieldy, but for a newbie it can be hard to understand. My single bigest complaint is that when there is a problem with the syntax (e.g. in web.xml) the error is typically not very informative. This in itself leads to allot of problems. sam

Re: out of environment space
Right, this has nothing to do with tomcat. Windows console applications use their environment space to store environment variables. Whats happening is that when you run tomcat, you're filling this space up so some of variables won't get saved - this could really screw tomcat up. You need to increase your default environment size. You can do it by creating a shortup to a dos program and change its properties, but probably the better way to do it is to add an entry to your config.sys file - can't remember exactly what you have to do though. Changing config.sys means all console apps will inherit this value.

Re: Define the /var/www to serve .jsp ?
When using tomcat and apache, you simply set up a new document root and mapping within httpd.conf for each webapp you want accessable via Apache. When you run tomcat, it automatically generates the Apache directives required to use Apache and Tomcat together uising mod_jk - look at the file mod_jk.conf-auto.

Re: Logging
Tomcat 4 supports filters, which may do exactly what you want. They are defined on the 2.3 spec IIRC. Basically, its a bit of code that gets accessed before the requested page. There was an article about the use of filters i think either on javaworld or servlets.com. Assuming you want a 3.2 anwser, then you could direct all traffic through a servlet (or several) which does the logging, and then have that servlet forward on to the original page, e.g.: http://myserver.com/LogAccess?page=userpage.jsp Would log access from the client, and forward the user to userpage.jsp.

Re: Formatting Apache+Tomcat Java stack output errors: how?
Well, IIRC the stack outputs simply get sent to Stderr (e.g. when you do excp.printStackTrace()). You could make stderr point to a different stream (can do it via the System object) and then have that output stream do the formatting. The exception reporting provided by Alphaworks JLog can certainly do some decent formatting (by-the-by, Jlog is NOT log4j, although they were both originally written by IBM). If you decide to use JLog, please check the license - it may still be under one of IBM's dodgy ones, as it was last time I looked (e.g. free to use, but if you use it in your code IBM can ask for your source code. And believe me, they've done it in the past!).

Re: What are EJB
Hmm...I can certainly send you the config files Orcas uses to work with Tomcat. I'll try and dig them out (off site at the moment - back next week). One way to communicate with an EJB container without any config problems at all, is to use RMI.You bind an RMI object at your EJB container's machine, which will act as a proxy to the EJB (mine is in fact called CentralServerProxy). Your servlets then act as an RMI client. All you have to do to get this to work is run tomcat with a security manager (so you'll need java 2, and you have to uncomment the relevent line out of your server.xml), start an RMI security manager before retrieving the reference to the object, and tailor your tomcat.policy file to allow access (I ended up granting everything full permissions because I couldn't be bothered to do it properly :-) ). The beauty of this approach is that: 1.)Tomcat doesn't have to be on the same machine as your EJB container as the communication is RMI (wouldn't be that secure though). It could even work over the web (RMI is simply a Java specific layer on Corba). 2.) You abstract the underlying EJB container. Different containers might require different configuration's for tomcat and the container itself to get communication to work. I can go into more detail if you want (I have the code here). It doesn't take too long to setup, and you can easily protoype the system without an EJB container behind your Proxy RMI object - you could equally just use JDBC to connect to MySql or something. Using servlets as an RMI client is outlines in the Servlet Programming book, in the odds and ends chapter I think (left my copy at the office!). Obviously you could use other communication mechanisms to abstract the communication - we also use 1024 bit encrypted secure pipes to communicate over the web between out central EJB server and client processes. sam - Original Message - From: Luba Powell [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, June 18, 2001 5:31 PM Subject: Re: What are EJB You think so?

Re: Problem with session tracking
There is a difference between the way HttpSessions arew created and handled,
and the Cookie objetc. The cookie object creates a persistant cookie on the
clients machine. The HttpSession is just a memory cookie, and as such is
non-persistant and doesn't sit on disk. Looking at your code,
request.getSession() will return either the current session, or will create
a new one if none exists. I would expect that your servlet is the first one
to create the session. Try accessing another servlet after this one - have
that servlet get the session and see if its new. You could just put a link
to itself on the servlets page. The example servlets include a session
example which does just this. Basically, there are several ways of tracking
sesions, and to make matters really complicated you can use allot of them at
once. It doesn't actually mean they share the data though :-)
It depends on circumstances and personal tastes as to which one you use.

Subject: Problem with session tracking
Hi there,
I'm having trouble with session tracking in a servlet in that the session
always appears to be new. When exercising the following code fragment:
HttpSession session = request.getSession();
if (session.isNew())
{
// Some stuff here
}
the isNew() call always evaluates to true. I also have noticed that no
cookies are being written since if I try:
Cookie[] cookies = request.getCookies();
System.out.print(Number of cookies is );
System.out.println(cookies.length);
it is always zero. However, if I write cookies myself by calling
response.addCookie(), I get a cookie next time round.
I'm finding this confusing since my understanding is that the session
tracking is by default implemented using cookies. I'm guessing that the lack
of cookies and the always-new-session are not unconnected but I've failed so
far to find a solution or a reference to this problem in the Tomcat FAQ.
btw, I do have cookies turned on in my browser and the noCookies
parameter in server.xml is set to false.
I would appreciate any ideas you might have.

Alan Goulding.

the mod_jk.conf-auto tomcat creates authomatically generates the apache directives so apache can see the contexts setup under tomcat. Whilst they use different document roots, you can easily make them look the same my tweaking the generated directives.

What would the scope of the book be? Will it be developing a webapp with jsp and servlets under tomcat, or will it just be about configuring and setting up tomcat?

Deployment using ANT Tomcat IIS Should of course cover both *nix setups and win32 setups. The first two I know a fair bit about. I know nothing about the second two.

Re: Multiple Unique Instances WITHOUT multiple JVM?
I think there is a simpler solution. Firstly, have one web app. Secondly, have a database (could even be an encyrpted text file) containing user information. When a user logs in. You check him against the database to confirm password etc. You asertain from this which company he works for and you load those properties. Each servlet's behaviour would depend on the company the user works for. e.g.servlet A displays page bob.jsp for company bob, but fred.jsp for company fred. The company properties would be stored in the session info. This relies on some decent authentication and session handling stuff, but makes your life allot simpler.

Re: Tomcat SSL
The ajpv12 protocol is still used to stop tomcat. As such even if you just use ajpv13 you should still start the ajpv12 connector to allow easy restarting of tomcat. I guess that eventually ajpv13 will be capable of handling a tomcat restart and ajpv12 can be removed completely. sam Wasn't there something about tomcat being more difficult to restart when using ajp13? Like apache had to be restarted as well? If true, I think that's too big an inconvenience to warrant switching.

Re: Tomcat SSL
You might have problems detecting if you are working over a secure connection. See if the isSecure() method works in a servlet when working over SSL. sam mod_jserv didn't support SSL neither ajp12. You must use mod_jk with ajp13 to get SSL info forwarded from Apache to Tomcat. [ ... ] Can you clarify what you mean bu this? Because I'm using Apache with mod_ssl, and Tomcat with mod_jserv, and things are working just fine. Perhaps there's some functionality I don't have, but I guess I haven't needed it yet.
SSL detection
I have Apache and Tomcat running together under SSL. I now want to create a page which only run under SSL. I want http and https to share the same documents however. My first idea is to simply have a tag handler, which detects the protocol, and if not SSL is simply redirects to a page explaning why they cannot view the requested document. By problem is that I'm not sure on the correct way to retrieve what type of protocol is being used. There is a getAuthType method in HttpServletRequest, but the return type is simply a string (e.g. BASIC or SSL). My concern is that this return could vary from browser to browser. Can I assume that if using SSL the return will always be the string SSL? Also, how can I detect which level of encryption is being used? Ideally, I'd like to restrict users to connecting using 128bit only, or at least issue a warning when its at 40bit. Thanks in advance, Sam

Re: SSL detection
I'm not sure if this is different on winNT, as I did it on Linux, and so these instructions are really for that. All the packages mentioned here i think also come with win32 instructions. First, get Apache using mod_ssl. Easiest way to do this is to download openssl 0.9.6a (www.openssl.org), the latest apache source (www.apache.org) and the mod_ssl source (search google - can't remember the url - maybe www.modssl.org ) The mod_ssl install file then explains how to build all 3 packages and get them running. Then get Apache serving .jsp and servlets via tomcat using the ajpv13 protocol (look at the Apache-Tomcat howto in the docs). The older ajpv12 protocol has some issues with SSL. The servlets and jsps should work equally well under https or http, with the exception (perhaps) of URL rewritting when the client has cookies disabled (search the archive for recent posts for more info). As I said, this worked for me on Linux, more specifically under SuSE 7.0. sam - Original Message - From: subbu [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, April 24, 2001 3:27 AM Subject: Re: SSL detection Hello SAM could U please tell me How to configure apache to support SSL (winnt) with love subbu. - Original Message - From: Sam Newman [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, April 23, 2001 3:59 AM Subject: SSL detection I have Apache and Tomcat running together under SSL.

Re: seems as though a servlet engine would have a little clearer documentation on getting servlets running
Go back to first prinicples. Try accessing the servlet directly via tomcat rather than worying about apache - try looking at http://youmachine:8080/yourcontext/servlet/YourServlet The port 8080 reefres to the port tomcat is running on. With no port specified, it means you are trying to access via the standard http port of 80, which is where Apache (or some other webserver) is running. If that works, its an Apache/mod_jk issue. If not, its a web.xml issue. Just to reassure you, tomcat does work - I wouldn't be at all suprised if it has the largest user base of all servlet engines currently on the market. If you find that doesn't work, please post your web.xml so we can have a look. If not, can you post the directives you use to get Apache running with mod_jk (probably the mod_jk.conf-auto file generated in tomcat/conf). regards, sam - Original Message - From: Dan Sharon [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, April 23, 2001 6:55 PM Subject: seems as though a servlet engine would have a little clearer documentation on getting servlets running ok, install tomcat, jsps are workin, made new context, jsps are workin in it, write a servlet(5 min), try to get servlet working(5 hr), read documentation, it says put servlets in WEB-INF/classes dir, did that it says add servlet to WEB-INF/web.xml, did that web-app servlet servlet-nameservtest.class/servlet-name servlet-classservtest.class/servlet-class /servlet /web-app restart tomcat(can't believe this has to be done everytime a servlet gets added or changed), did that it says call your servlet with http://thehost/WEB-APP/servlet/theservletname; did that response: 404 there's no servlet directory, kinda makes sense, but i thought mod_jk was taking care of that.

Re: WML and JSP
Its possible, but not trivial. It will inevitably result in the use of some kind of MVC setup.

Then code 2 different jsp files - one for WML, and one for HTML, both using the same taglib, just displaying the information in a different way. You could then get a servlet to handle the request and direct the user to the correct .jsp file. The O'Reilly Java Server Pages book has a good chapter on taglibs MVC stuff.

Re: newbie
Let me guess, these servlets are using sessions? When a session is first used, there is alarge lag whilst tomcat generates a list of large primes (I assume) to maintain unique sesion identifiers.

Re: Cleaning up servlets
Well, the servlet will get destroyed when the servelet is garbage collected I think. The JVM has a garbage collection thread which starts up automatically, and its its job to cleanup unused objects. I'm not sure if this behaviour changes in tomcat. You can explicitly call the garbage collector by calling System.gc(),or something similar. Note that something will only be garbage collected when nothing holds any references to it (an oversimplification I know).

If your happy with the old 2.0 spec, and the fact your unlikely to get much support if things do go wrong, I guess there isn't much reason to change.

Apache seems to identify servlets, b assuming that anything in a servlet directory is handled by tomcat, so servlets will always appear in a servlet directory.

To be honest I'd concentrate on the mod_jk howto rather than the Apache-Tomcat howto - its probably a little less confusing. Basically, mod_jk and jserv do the same thing, but jserv is old and has some issues. It also takes more work to get configured. Using mod_jk on its own is the way to go.

Re: Tomcat with Apache/URLRewritting and mod_rewrite

The problem I have is that when using Tomcat in standalone mode URL rewritting works, however, running Tomcat in combination with Apache does not, because Apache does not hand the request over to Tomcat. I think is is stange that there is nothing mentioned about this in the tomcat user guide - section Setting Tomcat up with Apache. I think so many people are using Tomcat with Apache that it is really a very important issue ?! I mean session tracking is fundamental and it should work using URL rewritting. I guess many people use cookies for session tracking instead of URL rewritting. Probably with cookies it should work, so maybe that`s why this issue hasn`t really come to the attention to the tomcat developers ? What do you think ? Just to clarify, are you using jserv or mod_jk? And if you are using mod_jk, are you using the ajpv13 protocl for connection? I'm using mod_jk and ajpv13, and am session tracking using the HttpSesession class and it works fine, as does parameter passing. I don't know too much about URL reqritting though. sam

Re: How to read property files?
You'll want to use getResource when your in a jar file. I've found the
safest way is just to know where the property file will be in relation to
the class loading it, and get the URL resource for the class itself. This
URL will differ for a class in a jar, but its still doable.

Re: Asking for an Opionio on Apache Tomcat or Just Apache
Please take a time to provide me with the following opinion. I spend some time configuring Tomcat and Apache. Because of deadline constaints and the fact that some allready developed code has been devloped using only Tomcat as standalone, the prototype team is focusing on just using Tomcat. Does anybody know if that approach is good? Personally I feel very reluctant in following that approach, but I have to convence by team leader why Tomcat by itself won't do the same work as Apache Tomcat together will. Any opinions are wellcome Beyond the fact that Apache will give you a wealth of options for configuration, it serves static pages MUCH faster than tomcat. Once you get SSL working with Apache, its pretty transparent to tomcat for example - your servlets will use SSL without any extra work by yourself. sam

Apache/Tomcat integration issues
I've just followed the instructions to get Apache and Tomcat working together. I editied the workers.properties file (which by the way seems to assume you are on a win32 platform!) and the server.xml to include the ajpv13 protocol connector. Apache includes tomcats autogenerated config file and everything works fine - I can see and execute all the example code. I basically have two problems however: 1.) The autogenerated conf file for mod_jk makes no reference of ajpv13, which I assumed is the prefered protocol. The only place I can see to make ajpv13 the default is for JServ. I obviously would like to avoid editing httpd.conf by hand and would rather tomcat generated the file using ajpv13 as the default - is it simply a matter of inserting a directive in the servler.xml? I appreciate that not everyone will choose to use ajpv13, but if its explicitly referenced in the server.xml, couldn't it be put in? What do I loose by not using ajpv13 (apart from performance)? 2.) When displaying one of my login servlets (a simple form forwarding requests to another servlet) via apache (over standard http or https) under netscape on a linux box, I get displayed the source code for the page (e.g. the plain text html) rather than the rendered page. Accessing the page via the tomcat port solves this. MSIE on my laptop can view the page fine - either via http or https. If it was a problem with the format of html i would of expected the tomcat served page to likewise display the html sourcecode. Any ideas? Thanks in advance, sam newman p.s. I'm tempted to buy redhat's strongohld out of my own pocket rather than spend another week of hell getting SSL working myself!
