I've managed to get a few apps working with the kdejava bindings and gcj. I 
dowloaded the kdejava and qtjava modules seperately and built them to create 
qtjava.jar and koala.jar.

I then compiled the two jars with: (kde installed in /usr/kde/cvs)

gcj -L/usr/kde/cvs/lib -lqtjava qtjava.jar -fjni -shared -o libqtjavabind.so

gcj -I<path to qtjava>/javalib -L/usr/kde/cvs/lib -lqtjavabind -lkdejava 
koala.jar -fjni -shared -o libkoalabind.so

You can check with ldd that the produced shared objects are linking correctly.

Then, for example, the KProgressTest.java example compiles with:

gcj KProgressTest.java --main=KProgressTest -o kprogresstest -lkoalabind 
-I<path>/qtjava/javalib -I <path>/kdejava/koala

Whilst the resulting executable worked fine, there was clearly a problem 
somewhere (probably in libgcj?) as when I left it running for a day or so, it 
ended up using 300 odd MB of RAM....

Hope this helps,

Daniel.
