what's running on my VM?

Is there a way to find out what processes are running on a Java VM?

When we shut Tomcat the console window that our app opened in does not close. We are thinking that this is because something associated with the app is still running.

However, just in general, I think it would be interesting to see what's running.

Thanks in advance for any guidance.

It's possible to list all the threads that are running in a JVM. The following piece of code does this. (Yes, it's so old that it generates HTML directly in a servlet - JSP didn't exist back then :-)

Thanks Ulf. I didn't realize that thread info was that readily available. I guess my question was not really 'advanced' java.

It is sorta covered in the JavaRanch Style Guide.
