It's probably just an oddity of Windows, maybe it kills the bat process but the child process is unaffected. The bat file runs java via: cmd.exe /c exit /b java. Maybe there's another way to invoke it that would work better? Eventually the Jython .bat file launcher will be replaced with a native .exe launcher -- if not by Jython 2.5.2 then likely the next release. That should solve this issue among other things: http://bugs.jython.org/issue1491 -- Philip Jenvey -- You received this message because you are subscribed to the Google Groups pylons-discuss group.

Programmatically shutting down Pylons server
Hi List, I have a Java class that I need to access from Python, and my solution for the time being is to wrap it in a Jython web service, using Pylons.

I'm hoping that I can simply expose a web service call that will shutdown Pylons. However, short of sys.exit(), I haven't been able to find anything, and I'm not even sure if that will work.
