It’'s scheduled for January 2007, so we may soon see some beta versions. As JM-356 is already fixed you could use a nightly build (quite stable but not recommended for production).
I did delpoy jwchat-1.0beta2.war in Tomcat some months ago with little problems but still some things to fix within JWChat to get it working good with Wildfire so I wonder if you hit a JHB problem.
