Yes, I'm definitely interested in learning more about this.
I picked up some code that was floating around on the derby-dev list
a few weeks back that basically did
cls.getProtectionDomain().getCodeSource().getLocation().toString();
I think maybe Rick was using this code in one of his patches.
Is this the technique that you mean, David?
thanks,

Yep, this is it, Bryan, I sent that code to Rick. Sounds like you're on
your way. I'm glad to see this happening -- I knew we could use it for
sysinfo but never got around to implementing it.
Look out for SecurityManager issues, however,
getProtectionDomain().getCodeSource() is a restricted operation...
