How to connect to openfire conference room via Smack API

Hi, I have a Smack 3.0.4 based Bot running, its fine, only I would really like to be able to connect to a conference room, but whatever I try doesn’t result in a connection listing in the conference room.

I have openfire 3.0.6a installed on localhost, ‘home’. I have a single conference ‘test@conference.home’, that I just cannot connect to (or at least, get listed as being connected). Is there a trick to connection to a conference room rather than another user via Smack?
