I'm running JBoss 3.2.3 with 2 nodes in the default partition. I have configured a
stateless session bean for clustering (with the default RoundRobin load-balancing
policy). When invoking the session bean from a client (outside of container JVM), the
load-balancing works fine. Each call to the session bean alternates between nodes as
expected. However, when invoking the methods on the same session bean from within a
message-driven bean, the calls are not load-balanced.
| public void onMessage(Message message)
| {
| try
| {
| MapMessage mapMessage = (MapMessage) message;
| String testMsg = mapMessage.getString("Test");
|
| InitialContext ctx = new InitialContext();
| TestSessionHome home = (TestSessionHome) PortableRemoteObject.narrow
| ( ctx.lookup ("TestSession"), TestSessionHome.class);
| TestSession session = home.create();
| session.test(testMsg + "A");
| session.test(testMsg + "B");
| }
| catch (Exception e)
| {
| e.printStackTrace();
| }
| }
|
The session bean simply logs the message to the System.out. Both A and B messages are
always processed by the same node. I would have expected one node to process message
"A" while the other node processes message "B".
Is it possible to have load-balanced session bean calls within the container? I've
read thru the JBoss clustering documentation a few times and didn't find any
solutions. Thanks in advance for the help.
