In our use of 4.2 we use an instance of JMSServerInterceptorSupport to detect when Clients unsubscribe or close their connection to Message Topics. With the change over to JBoss Messaging in 5.0 in JBoss AS 5, this functionality is no longer there. What methodology would we use to perform the same function? Not being able to do this, prevents us from upgrading to the latest release. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4195605#...
