incorrect time in the catalina.out logging
Hi All I am using tomcat 6.0.18 on RHEL 5. The problem is that the time that is printed in the logging of catalina.out is one hour ahead of the server time. For example, when the command line date command said Fri Mar 20 05:57:46 GMT 2009 The time printed in the catalina.out was 2009-03-20 06:57:03 Please advice how to fix the issue. Regards, Ghufran
Incomplete WAR deployment
Hello all, We seem to be having the same problem as discussed in this thread: http://marc.info/?l=tomcat-userm=117872182913850w=2 The problem being that Tomcat on rare occasions does not completely unpack a war file. Our install procedure is very cut and dry: 1) stop/kill any running Tomcat processes 2) delete the old installation rm -rf 3) re-install Tomcat 4) install multiple war files into the 'webapps' dir. 5) install other pieces of the application into other non-Tomcat dirs. 6) start Tomcat 99...% of the time Tomcat starts up without a hitch. But every once in a great while, not sure how often, Tomcat will simply fail to deploy the entire contents of the war. I've only witnessed it 3 times (QA states it's happened more times). It's happened on 2 different webapps, and the 1 this happened to twice had different resulting exploded dirs. That is, they didn't stop deploying in the same spot. One time it stopped about 50% through and the other time about 95% of the way through. When this happens there are no startup errors. Tomcat starts up and the log indicates all wars were successfully deployed. One doesn't know there's been a failure until you hit the servlet and get a ClassNotFoundException. One time the log4j properties failed to be deployed so there wasn't even a log indicating a CNFE. Just as the previous post states, to get the system working one has to: stop Tomcat, delete the exploded dir, then restart Tomcat. Has anyone else ever seen this? Does anyone have any ideas as to why this may be happening? Any solutions, other than manually pre-explode the war files? Env: Solaris, jdk 1.5, Tomcat 6.0.14, war built via maven 2.0.9 Thanks, O - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: configuration about tomcat for work with mysql/J connector

Re: form parameters
Joseph Millet wrote: Maybe I'm missing something but from the little knowledge I have, I'd think an HTML form is posted encoded in the form enclosing HTML document charset specified in the sent Server headers. So that you settle a page encoded in iso-8859-2, you wouldn't expect a form present in that page to post unicode data, would you ? Maybe we need to restate the issue a bit differently. Imagine a website on which there is a starting page with 3 links : - formA.html - formB.html - formC.html Each of these is a html page containing a tag 'form method=POST'. Now 3 users, each at his workstation, obtain this starting page from the server. Then userA clicks on the link to formA.html and obtains the corresponding page. Similarly, userB clicks on the second link etc.. The users fill in their respective forms, and submit their respective forms to the server (in any order). The process on the server which handles the first submission (whether it is a servlet in Tomcat, or a cgi-bin under httpd etc.. doesn't matter), has no idea where this submit data comes from, right ? (It could even come from a page obtained from another server). So the process in question has to evaluate this data, based only on what it gets in this specific POST. What we are discussing here is how, based only on the data coming in from the browser POST, the server process determines the correct character encoding of what it receives. And the answer so far is, it basically cannot be sure, because the browser does not send enough information with the POST, to allow the server process to determine this unambiguously. Of course, if the server process is sure that the form originally came from itself, and that all the forms composing this application are defined such that the browser *should* always encode the data in a specific way, then the process could reasonably assume a charset and encoding. But if one of the users uses a non-compliant browser that does not give a jot about what html is telling it to do, then .. A separate but connected question is that it seems that current browsers do not follow entirely the HTML specifications, and even for multipart/form-data submissions, do not send the charset/encoding headers that would enable the server to know for sure, athough they should. To go back to your note above : It is true that the browser, in the absence of other information, SHOULD consider that the data it is going to submit should be in the encoding of the page containing the form. This /can/ be changed by using the accept-charset attribute of the form tag. However, even if that is true and if the browser follows the specifications in that respect and does encode the data properly, it does not change what I mention above about the fact that the server is still really in the dark about what it gets. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Tomcat CPU 100%
Hi all, We have a java web application (deployed on Tomcat 5.5 with java 1.4) that has never had CPU problems. Some days ago we deployed a new version, that had non significant differences, and since this deploy we got frequent CPU 100% usage. users could not work and we needed to rollback to previuos version. The unique structural difference is the upgrade of the following libraries, used to generate jasperReports: - commons-beanutils-1.5 -- 1.7 - groovy-all-1.0-beta-10 -- groovy-all-1.0 - jasperreports-1.2.0 -- 1.3.3 - jdt-compiler -- 3.1.1 - added jasperreports-extensions-1.3.1 with the -Xrs option we could not get info about the hanging thread, so yesterday we deployed the new version, with old libraries and without -Xrs option. Now we get no CPU usage problem. Can you help us understand what the real problem could be?

Re: How to make Tomcat serve/listen to one more port?
I must admit that I'm lost, despite hours of readings I have to add that Tomcat documentation is never very clear and comprehensible. I can't see how a host can use such and such connector!? I mean, the connector's doc at http://tomcat.apache.org/tomcat-6.0-doc/config/http.htmldoesn't tell me which host I could attach it to. And host's doc at http://tomcat.apache.org/tomcat-6.0-doc/virtual-hosting-howto.html doesn't give any clue which connector to use. And I've a doubt that virtual hosting is actually what I was looking. Currently, I access the Tomcat's default website using an URL like this: http://myservername:x/ All I want to do is to have another website using an URL like this: http://myservername:y/ TIA On Thu, Mar 19, 2009 at 6:18 PM, Caldarale, Charles R chuck.caldar...@unisys.com wrote: From: Caldarale, Charles R [mailto:chuck.caldar...@unisys.com] Subject: RE: How to make Tomcat serve/listen to one more port? Correct; the Host element is equivalent to a web site, the Connectors just feed the Hosts, based on the name and Alias. Note that you don't really need multiple Connector elements to support multiple Hosts; one Connector will suffice, and it will route requests to the appropriate Host based on the URL. - Chuck
Issue with SSL server/ network configuration
Hi y'all, I have a fairly complex issue regarding Tomcat server configuration, so I'll try to explain: I have two web applications that need to run in one Tomcat server. Application 1 needs client certificates, so I need to configure an SSL connector with 'clientAuth=yes' Application 2 needs NO client certificates, and users should not be bothered with questions about client certificates; so I can not use 'clientAuth=want', I have to use 'clientAuth=no' here. Now the easiest thing to do (I think) is to have two keystores, two server certificates, two domain names; one for each application. Now the problem is right now: I only have one keystore, domain name, certificate (certificates cost money you know...). My question to you peoples: is there a simple way to map one domain name to two different SSL connectors? Port-forwarding based on web context? The latter seems possible, yet a bit flakey.

RE: Need Help With Clustered Tomcat Sessions
I feel I must apologise. Upon closer examination, it appears I am having the same problem with my Linux load-balancer as well. It looks like I may a compound issue. The initial confusion started with the different way that Linux and Windows Apache servers handle the trailing slash for a URL. The Windows Apache would not see the trailing slash and break, so I was able to notice the problem. The Linux Apache server would not see the trailing slash, but would gracefully work around it. The other issue may also be connected to the trailing slash issue but I'm not sure, I'll try to explain it as best I can. When I go to http://192.168.1.100/examples (no trailing slash), I actually get forwarded to a Tomcat server and end up at http://192.168.1.110:8080/examples . If this happens, the Session ID stays the same and all my name/value pairs accumulate in the session example. However, If I keep adding a trailing slash: http://192.168.1.100/examples/ http://192.168.1.100/examples/servlets/ etc. Then the URL in the address bar stays that of the load-balancer, BUT, every time I add a new name/value pair to the session example I get a new Session ID and my name/value pairs keep getting overwritten. This, of course, wont work because there is now no more load balancing or failover protection. So ... I am now not sure if this is a trailing slash issue or a sessions issue, both or neither. If I use a static page placed in: C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\examples\test.html the load-balancing and failover work perfectly. It appears to only break if there is some kind of session/dynamic content on the page. So what does everybody think? Is this a simple issue or more complex? Is this simply a URL Rewrite issue or something else? Thank you so much for reading and replying.

I know this seems like a simple question, and users new to Tomcat (or any servlet server) have a bit of difficulty, but it has a complex answer. Let me try to explain things a little bit: The most basic unit of work for a servlet container is the servlet itself. JSP files are translated on the fly into Java classes which are also servlets. Although the servlet is the most basic unit of work, the webapp is really the focus of the server, and the concept that is most difficult to grasp for someone coming from a PHP or Perl or other CGI background. A Java webapp is a collection of servlets, JSPs, static content, helper classes, and libraries all bundled together, often into a WAR file. A WAR file is just a JAR file with a specific directory layout to facilitate webapp deployment. A webapp needs to look like this (structurally): /The root of the webapp. Anything can go in here like static content, subdirectories of static content, etc. /WEB-INF This directory contains webapp configuration files /WEB-INF/web.xml This is the deployment descriptor which defines the mapping from URLs to servlets, as well as some other things. Read the web.xml from any Tomcat example to get an idea of what you can do. /WEB-INF/classes This directory contains your Java class files, in package directories (like com/mycompany/MyClass.class) /WEB-INF/lib This directory contains any JAR files on which your code depends. /META-INFThis directory holds information about the JAR/WAR itself. The jar utility will add a MANIFEST.MF file here to indicate how it was created, etc. /META-INF/context.xml This file is a Tomcat-specific deployment file. You will want to look at some Tomcat examples for more information. This file is optional if you do not have any special configuration. Note that in your case, you probably want one of these files, and you probably want to use it to set up your database connections. This page gives you a start-to-finish example of how to build a web application. I hope it helps: http://www.adp-gmbh.ch/blog/2004/october/13.html Unfortunately, most of the Tomcat documentation assumes that the reader already knows all about Java webapps and just needs to know how to get things running on Tomcat.

Once you've followed Chris' advice and learned how to build a webapp, you can specify the webapp location via a Context element in Tomcat. Webapps are normally deployed in the directory specifed by the appBase attribute of the Host element in conf/server.xml; if you want a different default location for all webapps, change that. If you just want to put a small number of webapps in a different location, create a file named conf/Catalina/[host]/[appName].xml containing a Context element with a docBase attribute whose value is the absolute location of the webapp. Relevant documentation links: http://tomcat.apache.org/tomcat-6.0-doc/appdev/index.html http://tomcat.apache.org/tomcat-6.0-doc/config/context.html http://tomcat.apache.org/tomcat-6.0-doc/config/host.html - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

FW: very off topic marketing question
Number of users is not the only one thing, you need to think about, when you are choosing technology. PHP is a _scripting_ language with out of _static typization_, multi-threading, full OOP support and its API is pretty weak too. Also it is _not_ designed for servlet ideology: each request runs script from the very beginning. You can use fast_cgi, but sometimes it is painfull procedure too. But it is fast and easy-to-use. Apache + PHP may run on P-166/64 RAM/FreeBSD serving phorum for ~ 100 users with out of troubles. Programs are small too, like in all scripting languages. If you are going to move to php, be ready to: 1) loose tools like log4j. 2) meet API, 10% of which uses OOP and exceptions, and 90% is procedure / errors based. 3) you would not have namespaces. 4) because of dynamic typization, you would be able to find some types of errors only in runtime. 5) no multithreading etc... -Original Message- From: Jason Pyeron [mailto:jpye...@pdinc.us] Sent: Friday, March 20, 2009 6:04 PM To: 'Tomcat Users List' Subject: very off topic marketing question I have a client that is confused why we are giving them a J2EE product and they are concerned with performance and scalability.

Parameterizing log4j.properties/xml files
All,
Apologies if I've missed the answer to this in the Logging HowTo, the
FAQ, or Andre's collection of the logging discussion.
Env: TC 6.0.18 + Java 1.5
The issue: I want to have several instances of the same webapp running
on the same Tomcat as myapp1, myapp2, etc.
That's easy.
I'm going to be using log4j, probably with properties files, but xml
would be ok too.
I'd like to have log files named mylog.log appear in ${catalina.home}/
logs looking like
myapp1-mylog.logmyapp2-mylog.log... etc.
I could hardwire this in separte log4j.properties files for each myapp
instance, something like this:
log4j.appender.myLogFile.File=${catalina.home}/logs/myapp1-mylog.log
log4j.appender.myLogFile.File=${catalina.home}/logs/myapp2-mylog.log
And using ant to build my war files, I could hide this ugliness, just
copying such hardwired files into the war being built.
But is there any parameter syntax that would allow me to grab the
context name and write one log4j.properties with something like this:
log4j.appender.myLogFile.File=${catalina.home}/logs/${context-name}-
mylog.log ??
Thanks,
Ken

Just ask them to google for security-issues linked to PHP and issues linked to any servlet-container (aka Tomcat).

OK, that's not about performance, but we f.e. do not use PHP due to it's security-footprint.

From: Martin Gainty [mailto:mgai...@hotmail.com] Apache is hamstrung by the number of prefork processes it can spawn.. Yes. For this job, it's hamstrung by the PHP process being single-threaded and therefore having to spawn and keep multiple copies (each with its own address space) to handle concurrent requests. In other words: PHP (at least up to PHP5) is architecturally unsuitable for high-throughput services. It can be made to work, as Facebook demonstrates; but there are better architectures that have lower overhead. Actually, that's an interesting question. I wonder how many tonnes of carbon would be saved per annum if Facebook were reimplemented in something that allowed multiple threading and smaller sessions, such as Mono/ASP.Net or glassfish/servlets? ducks and runs to avoid the PHP lynch mob - Peter - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I do not need JSP to generate XML, so I use sevlet output directly. 2) You can precompile JSP (well, you can precompile PHP too, see Zend Compiler) 3) Most of logic in java web-app is stored in .class files, not in JSP pages.

It might also be good to temporarily activate the access log of Tomcat too, in order to check, whether the 503 already came from there or not. I would expect the develop observation and this one are two different things. Actually I was trying to draw comparison to the original poster, Tim Redding's comments about how the file size on a static page would change. Unfortunately, I gave you a bad example, which included the 503 error. Please ignore that. Basically, in the access_log we see the file size change, because it is serving the wrong page.

This is very good information. Nice investigation, especially because it leads directly to a conclusion: Your JSESSIONID cookies have the wrong information in them. Get yourself an HTTP sniffer to verify that this is what is happening: 1. You make a connection to http://192.168.1.100/examples/ 2. The request is re-routed to http://192.168.1.110:8080/examples/ 3. The server responds with a Set-Cookie header including host=192.168.1.110 4. Your next request goes to http://192.168.1.100/examples/, so the browser never sends the JSESSIONID cookie back to the server You need to make sure that the URL the client sees matches the hostname used in the Set-Cookie header. When you leave-off the trailing /, the server sends a REDIRECT back to the client and says go to http://192.168.1.110:8080/examples/;, and then everything works fine (because the hostname changes as far as the client is concerned). How do you have Apache talking to Tomcat? Are you using mod_proxy_http? mod_proxy_ajp? mod_jk? So what does everybody think? Is this a simple issue or more complex?

Log4j allows for parameterizing its own log files, but you'd have to set

Re: Parameterizing log4j.properties/xml files
I was doing something like this with LogBack (successor to log4j more or less),
but I'm no longer using it and don't remember how I set it up. The class
starts as follows:
public final class InitLogback extends HttpServlet {
@Override
public void init() {
final String pathPrefix = getServletContext().getRealPath(/);
And I think pathPrefix then contains the name of the directory in the tomcat
webapps folder.
I don't remember how I was configuring this servlet in the web.xml file;
possibly as a regular servlet with a load-on-startup value that was lower than
the main (Spring) servlet.
I don't claim that this is the best way to accomplish this.
If you're using Spring you may want to look at its
org.springframework.web.util.Log4jWebConfigurer
and
org.springframework.web.util.Log4jConfigListener

I could hardwire this in separte log4j.properties files for each myapp

log4j.appender.myLogFile.File=${catalina.home}/logs/myapp1-mylog.log
log4j.appender.myLogFile.File=${catalina.home}/logs/myapp2-mylog.log
And using ant to build my war files, I could hide this ugliness, just
copying such hardwired files into the war being built.
But is there any parameter syntax that would allow me to grab the

Re: FW: very off topic marketing question
Meh. Most Java webapps aren't multithreaded anyway in the sense that
each request lives in its own little world and usually runs start to
finish with no other threading involved.
Just this week I added threading to a component of my web-app. I had some
what dreaded it, but found that it took me only a half-hour and about 10
extra lines of code, here's a synopsis:
Thread t = new Thread(new Runnable() {
public void run() {
...blast()
}
}, Blast Thread);
t.start();
Where blast() iterates thru several thousand records, which are sent to a
third-party site for processing. The third-party site allows no more than 5
connections per second, so I just call Thread.sleep(1000) on every 5th
record.
It is very simple, very elegant and very fast now that some much load has
been moved off the main http thread.
My question is: how would this be accomplished in PHP? Would I need to
recompile the whole php server with a special thread package or what?

I did send to httpd, but I didn't see that apache was going to do what I was looking for, at least w/ mods only. I'm still looking into that also. Hope that helps clarify.

If Tomcat would allow me to do this, can I get a short desc of what I need to do? I think I have seen this question before, maybe on another list (Apache httpd?). And you are probably not getting the answer you want, because the way you write the question above does not seem to make a lot of sense. For example, these two lines appear to be contradictory : - allows me to grab the URL and build a web page. - then forward the request to the destination. Because in the server who gets the request, you normally /either/ build a response html page and return it to the browser, /or/ you pass the request further to another server, but not both at the same time. Can you try and rephrase your question in another way, or give an example of what you would really like to do ? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: help building a proxy
If you mean that there are no modifications to the original request or even the response, then yes. It's to be a transparent proxy.
