[jdev] JSO - Best Choice for Java Jabber Application?

[Sven.Bornemann at materna.de]

Hi everyone!
I would like to write a Jabber Java component/server that receives
presence data from and publishes presence data into a jabber network
(each direction for multiple accounts).
During evaluating the available Java APIs, I found out, that JSO seems
to be a good approach (may be the only way in Java??). But the last JSO 
release is of 2005. Is it such perfect or not maintained anymore?

Thanks in advance,
Sven
