I'm comming late into this thread and don't see the whole problem
here, but beyond what Brennan suggested this also works for me:
this.getClass().getProtectionDomain().getCodeSource().getLocation());
Where 'this' could be any object reference. Also, don't forget the
happy axis page shows the jar locations of everything loaded.
