before I write one (yeah right) has a j2me jabber client that does conferencing been written yet? tx
I see that there are many J2ME jabber clients available. Follow this link to learn more: http://www.jabber.org/software/clients.html.
You can also try to use Smack in J2ME but you will need to make some changes. Some people in the forums already tried the convertion and AFAIK it’'s working fine. There was a post some time ago with the instructions of the changes that need to be done.
I made a small one that works… I put the smack portion on the server and have the j2me communicate to it thru sockets.
then I found this! http://Jmirc.sourceforge.net <-- pretty sweet
I put it up at http://sourceforge.net/projects/elechat/ in case you want to try it out
