Tomcat doesn't stop if a java thread is running
I have this problem. If in my web application running in Tomcat there is a
java thread running when i stop Tomcat with shutdown.bat or shutdown.sh
tomcat process doesn't end and i have to kill it manually. How can i solve
this problem? Is there anything to change in java threads code?
thank you.

Make this thread a daemon (setDaemon(true)) in constructor.
This will tell the VM that its ok to exit without waiting for this thread.
If you want to give the Thread the possibility to finish some job
before shutting down, don't make it daemon, but register a
ShutdownHook instead.
Also, in the latter case, check for Executor patterns in java 1.5

The JVM won't terminate until all non-daemon threads have ended. If your
webapp starts such a thread it has the responsibility to stop it when
needed. You can use a ServletContextListener to do this.
