Hi, Here my query is "i need to check particluar durable scbscriber whether it has subscribed(active) or not from client". I am using Jboss-messaging-1.4.0. I have analyzed some jboss codes and i understood that, i could implement by PostOffice Object. But i have tried to create the PostOffice object thru ServerPeer object. But i am not able to proceed with any way to create ServerPeer Object. Please let me know how to create the PostOffice object with any basic sample code. Thanks in advance.
