Unable to create room on jabberd 1.4.3 muc

[Ms Linuz <deb_milist@yahoo.com.sg>]

So, I'm currently testing in jabberd 1.4.3 on debian sarge machine.
( I prefered of using ejabberd but I don't like compiling a non
standard debian package ).
As, debian comes with jabber-muc, I've installed to enable muc in
this jabber server. I have enabled the /etc/default/jabber-muc and muc
is started.
When creating room with Gaim's got "Error:502 Unable to deliver,
destination unknown"
Jabber log " bouncing a packet to myroom@conference.jabber.server.net
/tester from tester@jabber.server.net/Gaim: Unable to deliver,
destination unknown"
Below is xml file for muc.
Thanks and sorry for this long mail ;-)
