My work with java has been only small, just working on stuff with my website, I did have more of an interest when I was sorting out some java games.
http://filesharingtalk.com/vb3/software/t-emulator-j2me-suite-148424
The most interesting for me was this and it works very well,
it's close to Net Disaster > http://www.netdisaster.com/
some nice code :)
