Hello..
I have a simple question if someone may know the answer....

If I run some java program from jar file, can I get phisical location
of that jar file dinamicly?

I mean if I have main class let's say:
"org.classes.main"
packed into "C:\jarfile.jar" (or "/usr/home/me/jarfile.jar" :) )

can I dinamicaly get location of that jar?

I want to use it as an resource, but don't want to be bind to single
jar name...

Thanks,
FrenKy

File moduleFile = new File
(YOURCLASSHERE.class.getProtectionDomain()
.getCodeSource().getLocation().toURI());

File jarFile = new File
(org.classes.main.class.getProtectionDomain()
.getCodeSource().getLocation().toURI());

You should take me out of your killfile so you don't reply to questions
that I've already answered. ;-)

All solutions work like a charm :)
I went with
File jarFile = new File
(org.classes.main.class.getProtectionDomain()
.getCodeSource().getLocation().toURI());

Thanks all!
