Tomcat sessions in profiler

We've had some performance issues with tomcat, and stuck it in JProfiler, and seen something strange. We load our portal page and then log out. After a while, new StandardSessions appear in the profiler! Does Tomcat use sessions for some internal stuff? Any other ideas? It's hard to tell

Re: Tomcat sessions in profiler

This is internal so no spiders, and no monitoring on it. Nothing in the logs either... cheers, David Hassan Schroeder [EMAIL PROTECTED] 06/02/2008 03:21 PM Please respond to Tomcat Users List users@tomcat.apache.org To Tomcat Users List users@tomcat.apache.org cc Subject Re: Tomcat

Tomcat suddenly dies without a whisper

Hi, We are running Tomcat 5.5 on a powerful VM Server. MS Sql Server is also on the VM. It is fronted by an apache web server on another box. When under load (heavy but not excessive) we suddenly find tomcat dies, without any error messages we can find. Memory looks good. We are a little

Hi Chuck, I did see reference to that OOM killer, but the VM we are running on is 64 bit Windows. I was referring to the heap memory usage. any suggestions on where else to look? cheers, David x54680 Caldarale, Charles R [EMAIL PROTECTED] 05/15/2008 11:53 PM Please respond to Tomcat

RE: Tomcat suddenly dies without a whisper

Hi, Sorry - didn't mean to be confusing. We are indeed running in a virtualized environment, and the OS of the image we are running on is 64 bit Windows Server 2003. The JVM on that image is Java 6. Have you checked *all* of the Tomcat logs? Are you perhaps getting a normal shutdown? Yes,

Re: JSF implementation selection

We are running Tomcat 5.5 using the SSO Valve. We are hitting a strange situation, however, if we set the session timeout on our context to be less than the default 30 minutes eg 5 mins. The valve has the following check: if (((session.getMaxInactiveInterval() 0) (System.currentTimeMillis()

recognise tomcat finished starting up

Hi, We're trying to automate our acceptance tests and performing a remote install first. However, we have no way to know when Tomcat has finished starting so the tests can run. Has anyone any suggestions on the best way to do this? We're using maven and JUnit. cheers, David

Re: recognise tomcat finished starting up

Thanks for the responses...I'll try the listener creating some kind of file I can check for the existence of - this is complicated by trying to do it remotely... A loop-on-fail in the first test would work...as long as my first test never breaks ;-) cheers, David

Hi Martin, Thanks for the link... I'm actually running the tests against a remote installed tomcat, by poking it over http akin to HTTPUnit. However, I'm working on automating the remote install and uninstall too. I have it working, but am trying to figure out how to tell whether the install

Okso back to my original question! ;-) Any idea what's hidden in tomcat5.exe that is different from running startup.bat, and prevents Cobertura from recognizing when the server is shutdown? cheers, David x54680

RE: Tomcat Cobertura

Hi Chuck, Digging through the Cobertura code, it looks like it's making the following call: Runtime.getRuntime().addShutdownHook(new Thread(saveTimer)); it's run() method simply has the call to save the project data. This should be guaranteed to run (with the usual limitations of sudden

Does Tomcat 5.5's classloader handle classpath*

Hi, There is a mechanism in Spring to load all classpath resources that match a particular name using classpath*:myfilename. Apparently various classloaders behave differently in this respect - see http://static.springframework.org/spring/docs/2.0.x/reference/resources.html#d0e5951 and
