I would suggest trying GCJ's java-gui-branch AWT/Swing as Tom > Fitzsimmons has suggested. Please let us know how that goes.
After several tries, and resolving several dependancies not mentioned in jhbuild sanitycheck (if anyone knows how to list installed Debian packages by install date/time, I can submit a complete list) I've succeeded in completing the jhbuild as outlined in http://people.redhat.com/fitzsim/gcj-and-jhbuild.html. As David said, the AWT/Swing branch of gcj has no problems with my test case (see attached screen print). It runs fine both interpreted and as a native app. I will attepmt to compile my entire project to a native app as soon as I can, and see how that goes. In the meantime, should I attempt to determine why the layout works in gcj, but not in kaffe (see other screenshot)? I've attached my test source file again, in case anyone is interested in running the test case in their own VM, or if anyone else wants to look for the problem in kaffe. > > Cheers, > -David Jee -- James Damour (Suvarov454) <[EMAIL PROTECTED]>
