The latest version of the service manager (aka tomcatNw.exe) has the ability
to generate a thread dump for Tomcat running as a service. If this isn't an
option in the menu on your version, you can upgrade just this component by
grabbing tomcat6.exe and tomcat6w.exe from the most recent 6.0 distro and
renaming the files as needed.

This assumes the OP has the manager installed. Difficult to tell, as the OP
didn't give us a Tomcat version.

Johnny, *read the question before posting*. The OP has already stated that
they're running as a Windows service. No DOS box.
To the OP: If you're on a recent enough JDK (1.6), use jstack. If you're on
an older JDK, you might want to upgrade just to get this ability :-).
http://blogs.sun.com/pcmreddy/entry/using_jstack_on_windows gives an
overview of using jstack.
http://java.sun.com/javase/6/docs/technotes/tools/share/jstack.html is the
Sun documentation for it.
