[JDEV] Roster ??

[chandan sonaye]

Hi all,
        I am working in a Internet-based project. In the project, we are

developing an Instant Messaging client using Jabber Server in Visual
C++.

I want to add same user in more than group.
I have tried it. But when I add same item second time with different
group-name,
the first group name with that same name gets removed from my roster.

But I want to have this feature: that is  to add same user in more than
group.
Does Jabber provide this feature?
If yes, can you tell me in some detaill?
Or if it doesn't provide this feature, how should I handle this?

Thanking you,

chandan.
