Thanks for your answer. I appreciate. Here is the objective we have:
We want a client to be able to subscribe to different Topics.
We have for example
- subscribe to Group Notification (each time a group of user is modified)
- subscribe to contentRoom (each time a contentRoom is updated).
On the server side, we have several ContentRoom and Group which are
identified by Id (anf java listener via hashtable)
So we would like the Client to subscribe for example
group=groupId1 or
ContentRoom=contentRoomId2
On the server side we need the code to parse correctly the topic value,
such as it (the server) extracts the groupId or ContentRoomId and then drill
down into the low level API (SIP etc..) to start the appropriate listener
for these Ids...
this is the reason why I try to extract the content of the Topic set by the
Client.
I appreciate your responsive support.
Thanks for your help
Cheers
