EJB 3.0 load balancing not working in a Jboss AS 5.1 cluster

[kedarpjoshi]

Hi,

I am using Jboss AS 5.1 GA. I have built a clustered deployment of my EJB 3.0 Stateless Session beans. I have two nodes node 1 and node 2. Beans are marked as clustered in jboss.xml with load balance policy 'RoundRobin'.

My problem, the beans are no balancing the load whenever a call to bean is made from server VM. For instance, POJO's from node 1 make a bean call and they are served by beans in node 1 only. Even though there are free beans available in node 2, they are never routed to node 2. Can you please tell me why this is happening? Do I need to write my own load balancing interceptor or something?

thanks in advance,
regards,
Kedar

When you start the server nodes in a cluster, do you see any logs which show that those 2 nodes are being considered part of the cluster? Logs like, "2 members..." in the cluster? Can you post the relevant console logs (not server.log)


While posting logs or xml content or code, please remember to wrap it in a code block by using the Code button in the message editor window. Please use the Preview button to ensure that your post is correctly formatted.

Also are those stateful session beans or stateless session beans? And please post relevant configuration files (jboss.xml) and any relevant code.

Yes they do form a cluster. This is not something that i have missed but in general how jboss AS behaves. Please see following link -

I do not hot this user got it working finally? Jboss by default re-routes the call to a bean from the node within a cluster to the same node. This happens because of an interceptor. The option of disabling the interceptor dint work for me because it throws several exceptions. The only option i have is to write my own custom interceptor. But would it work? The guy who posted above links faced some exceptions.
