I haven't tried GUI stuff with JIGS for ages ...

Try first a non-JIGS, pure GNUstep application ... once that is working,        
at least the existing JIGS examples should work (if not, it should not be       
difficult to fix them).                                                         
                                                                                
Unfortunately, while JIGS is being used extensively in live environments
for non-GUI software (by the company I work for btw), I don't think it has
been used much for GUI software, so it might be not as mature in that area
(there definitely is a problem with subclassing GUI elements from Java - 
problem which is not necessarily easy to solve).

I haven't been able to use anything but Sun's JDK because JIGS needs some
features (weak references in JNI and other stuff) that are only available
in more recent versions of JNI and are not available in kaffe or such.  A
pity because it would be really nice to use a free Java environment rather
than Sun's one.  Maybe kaffe (or other Java implementations you know of)
might have got enough better in the meanwhile that it might work ...

Thanks
