Re: [Wrapper-user] Re2: application runs a thread - Tomcat does not stop completely

[<nic...@uk...>]

I havent seen tomcat actually do this... (later version might..)

The correct approach is not to use a servlet.

Instead use a Servlet Listener.

Yes, but what if the servlet is collected by the container during normal
garbage collection?  After all, the servlet that launches the thread is
not doing anything.  If it gets collected, destroy is called and my
thread would end!

 You need to use your serlvlet destroy() method to stop your thread (I
 assume you are starting the thread in a servlet)....

 I do a ;

 while (continue) {
       whatever();
       nap();
 }

 and get the destroy to toggle "continue"

 Subject:    [Wrapper-user] application runs a thread - Tomcat does not
stop
        completely


 Hello - I cannot seem to get my Tomcat application to stop completely
on
 Windows XP.

 I think I know generally what is happening.  The shutdown is issued to
 Tomcat correctly.  However, my application runs a thread, which sleeps
 for an interval, wakes up, then goes back to sleep.  The servlet
 container is not exiting because it is waiting for all of the threads
to
 end.  When I try the service shutdown while the thread is running I get
 this in the log:

 ERROR  | wrapper  | 2005/02/15 16:37:38 | Shutdown failed: Timed out
 waiting for signal from JVM.
 ERROR  | wrapper  | 2005/02/15 16:37:39 | JVM did not exit on request,
 terminated

 If I end my Thread before stopping the service, it all works hunky
dory.
 However, I do not want to rely on the user stopping the thread.

 I want to be able to call one of my classes so I can shut down the
 application"s thread.  I have tried everything, mostly using
 WrapperStartStopApp.  Help!

  -Dave
