SparkWeb conference room is not working

I am relatively new to the world of sparkweb and openfire. I have set up a conference room in openfire and successfully invited users to the room so long as the users are using the spark windows client (2.5.8). However, l am not having much luck using the conference service in sparkweb.

There is a Conferences tab at the bottom of the sparkweb page. When l click the tab, nothing shows. (Please see the attached screen shot). When l click the button (+) to add a conference server, l get the message: “Looking up conference sewrvice …” which goes on for a long time and nothing happens.

Could anyone please let me know where l might have gone wrong with config settings? Is conferencing possible from sparkweb? I am using openfire 3.6, sparkweb 0.9, OS: Windows XP .
