Re: [TCLUG-DEVEL:306] Linux/Java Question

Could be it's not using the path that you expect.  Better yet just use the
GZInputStream and GZOutputSteam classes in the java.util.zip package.  After
you unzip it you just need to untar the files.  I've seen a tar package out
there too, but I can't remember where offhand.
