In the *.app/Contents/Info.plist you'll find an entry pointing to the  
actual file to be executed (which is supposed to be inside *.app/ 
Contents/MacOS). And that file can be a shell script.

Now, you don't need the complex bundle structure we have been using  
for gvSIG <2. You only need the inner *.app bundle; the "outer" one is  
only to check for and install JAI-ImageIO if needed. Which is not your  
case because you already put it into SoyLatte.

(gvSIG 2 will also do without the outer bundle, since we have learnt  
that JAI-ImageIO causes Firefox and Opera to die when loading Java  
applets, and so we don't install it system-wide but use it as an  
extra .jar in the classpath)
(remember to take out the jai-imageio.jar from your ~/Library/Java/ 
Extensions !)

A hopefully minor problem will be that you won't be able to "osx-ize"  
the user experience as much as with the Apple-provided JavaStub.  
Expect problems with the app icon and name while running, for example.  
(or maybe SoyLatte has already been prepared for that?...). I think  
you could overcome that by creating your own substitute of the  
JavaStub, with a little Cocoa program which would present itself as  
gvSIG to the OS and start an embedded JVM which would run the actual  
program....

Also, can you confirm that the native functionalities (like loading a  
TIFF) do work?

I think we could polish a bit the whole thing and prepare it so  
different versions of gvSIG can be dropped-in, if you agree.

Cheers!
