1. When im connecting to the HornetQ task service with
+String name = "client 1" ;+
+TaskClient client = new TaskClient(new HornetQTaskClientConnector(name, new HornetQTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));+
and operate on the tasks with client.start() and client.complete(), im getting this classcastexception.
+Exception in thread "Thread-2" java.lang.RuntimeException: Client Exception with class class org.jbpm.task.service.hornetq.HornetQTaskClientConnector$1 using port 5445+
+Â Â Â Â Â Â Â Â Â at org.jbpm.task.service.hornetq.HornetQTaskClientConnector$1.run(HornetQTaskClientConnector.java:134)+

+Â Â Â Â Â Â Â Â Â at org.jbpm.task.service.hornetq.HornetQTaskClientConnector$1.run(HornetQTaskClientConnector.java:120)+
2. But if i connect to the service with adding a random number.
+String name = "client 1" ++UUID.randomUUID();+
+TaskClient client = new TaskClient(new HornetQTaskClientConnector(name, new HornetQTaskClientHandler(SystemEventListenerFactory.getSystemEventListener())));+
Im getting java heap space issue with too many open client session.
Is it a problem because as im not disconnecting client (client.disconnect()) .?
Is there any simple example of using HornetQ.?
Kinldy help in this issue.
