Automatic topic creation & deletion through EJBSessionBean.

[sasimsit]

Hi
I have big question like how to Automatic topic creation & deletion through EJBSessionBean, It can similer in Weblogic like

ht.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL, url);
ht.put(Context.SECURITY_PRINCIPAL, user1);
ht.put(Context.SECURITY_CREDENTIALS, pass1);

iniCtx=new InitialContext(ht);

JMSModuleHelper.deleteTopic(iniCtx,"Module",topicName);

and as well as
JMSModuleHelper.createTopic(iniCtx,"Module",jmsServer,topicName,topicName);

If possible in JBOSS server side. please provide API and small sample peases.

Why do you need a whole topic for each user?

Surely you can use one topic with subscriptions based on some kind of user-id filter
in the message?

NonDurable Topic subscriptions are automatically deleted when the connection
is closed or fails.

Anyway this is a consulting question not a technical question.
I'm not going to design your application for you. :-)

NonDurable Topic subscriptions are automatically deleted when the connection
is closed or fails.

Or if you want messages to survive failures you could use durable topic subscriptions
and map the login/logout to createDurableSubscription() and unsubscribe()
respectively.
