I'm not sure if Qt 2.3.x was even wrapped with QtJava. I've just had a look at 
the ChangeLog and I could only see a mention of Qt 2.2.4 - I think that was 
the last Qt 2.x version before switching to Qt 3.x.

The code generation of the kalyptus header parser tool has been rewritten and 
greatly improved for the recent KDE 3.2 release, so it might be possible to 
generate the bindings against the Qt 2.3.x headers. Use kalyptus from 
kdebindings HEAD with a '-fjni' option against the headers, and it will 
generate the .cpp and .java sources. The .h headers are generated from the 
compiled java classes via javah, so they are autogenerated too.

Otherwise I would just comment out any JNI methods which cause problems 
(assuming you don't need to construct QCanvasPolygons in your code).
