With this much information its easy to diagnose any memory leak in Java, but as you said most of the time just increasing size of heap or permgen memory area. RAM 16GB.JBoss configuration: 5.1, heap size 1024mb.We have a servlet (Web Container we are using is JBoss) which takes request coming from mobile phones, process it (which is lengthy process) then communicate with our server (MEAP server, built using C and C++) using socket

This was because the sql script from your post starts the increment at 5 for the tables, but the sql insert into the join table links the user with id 1 and id 2. The question is how do i add css styles to this example? I think we need to map the css somehow, i saw on google some example by using servlet mapping, but cannot make it work in this example

This window will either be the Java process that runs as a CMD window when WebLogic is launched as a separate process or service, or it will be the server log window when running WebLogic from Eclipse. However, there may be occasions during development or staging that you will want to run a local copy or different version than the one loaded from the modules directory - I have not tested this scenario yet, a test of the 3 use cases will be required

Memory Leak in tomcat due threads are not kill while stopping tomcat (Tomcat forum at JavaRanch)

Which isn't a Tomcat memory leak, it's a case where when a webapp is redeployed memory from the PermGen pool isn't freed due to classloader ambiguities. If you see 100 after you have sent 100 messages, then you need to investigate further (in this case I'd suspect that the API that is sending these messages -whatever that means- is not being used correctly)

Great article Javin, Though I agree that JDBC drivers especially MySQL JDBC Drivers cause some classloader memory leak in tomcat, I am not fully agree with solution of putting JDBC drivers on Tomcat lib. Another common culprit is ThreadLocal, avoid using it until you need it absolutely, if do you make sure to set them null or free any object ThreadLocal variables are holding

Yes, Tomcat 7 does automatically deregister it, but it that REALLY taking control of your code and a good coding practice? Surely YOU want to know that you have all the correct code in place to close all your objects, shut down database connection pool threads, and get rid of all warnings
