One of the positive things about using the Java programming language is the mass of Free Software libraries and applications written in that programming language. There are even several certified Free Software J2EE environments, like JOnAS. Since Free Software written in the Java programming language needs to be liberated from the Java trap, I play off and on with software that I haven't tested against Kaffe successfully yet.
With a lot of help from Andrew Haley from gcj (who spent a lot of time making JOnAS work well on gcj and GNU Classpath since last FOSDEM) and Florent Benoit from JOnAS, I managed to get the JOnAS to fire up, and wiggle around on Kaffe's CVS head (with a patch or two). Instructions are at the Kaffe OpenVM mailing list, and may work for other GNU Classpath runtimes as well.
If you are using text mode browsers, you should then be able to use links to connect to port 9000 on localhost and get an impressively styled down, cool retro screenshot
If you are using Firefox, then you can see the JOnAS console in its full whaling glory.
I guess Kaffe 1.1.6 is now really ready for release, and I am ready for the GNU Classpath DevJam.
