PubSub administration

Hello,

I’m new in the world of XMPP (I’m making some test with the Groovy language with the Smack library), and I’m very interesting in PuSub. So, I thought find some web administrative pages with the last Open Fire server, like displaying PubSub nodes, concerning PubSub implementation.

Where can I find such pages? Also, I would like find some articles/samples with code to use PubSub extension with OpenFire.

Thank you!

Bertrand.
