[news.eclipse.tools] Finding the jar file location

[Mark@xxxxxxxx (Mark)]

Hi folks,
         I posted a question recently and in one of the response's someone
mentioned how to find the physical location of the jar file from which a
class has been loaded. 

Currently I'm experiencing terrible versioning issues with my stuff and
could really do with this code..

Is there anyone out there that know's this code or else can I somehow
search this list's archive in some way?

Thanks,
Mark.
