[Gvsig_english] gvSIG and Java on Mac OS X

[Benjamin Ducke]

OK, this all sounds promising and straight-forward.

Indeed: the SoyLatte JRE runs on X11, so for anyone to use this version,
they have to:

1. Make sure X11 is installed
2. Live with the fact that it looks like an X11 app (So what?)

I will "unbundle" things as you suggested. I will also give it some
more intensive testing. If that's useful for you as well: all the
better!

Is there a way for my shell script to know it's own location in the file
system, so it can figure out all needed paths?

For this week, I will give it a rest and resume work on it on Monday.

Thanks a lot again for all the help and have a nice weekend!

Ben
