We have set up a three node cluster and we need to make a Stateful EJB 
aplication clustered, there. So we developed a stateful session bean and a 
servlet to access it. These are the steps we followed.

1. Started three nodes in "all" configuration of JBoss. (They detected each 
other)

2. Developed a stateful EJB which produces a Fibonacci series that makes the 
cpu busy. (Seperate jar)

3. Developed a client web application seperately running on the server which 
accesses the EJB. (Servlet)

4. Added a <clustered>true</clustered> xml entry in jboss.xml.

5. Made "provider url" in run time as follows
anonymous wrote : 
properties.setProperty(javax.naming.Context.PROVIDER_URL,"praplk:1100,cmbtr3:1100,utswlk:1100");

6. Made the EJB available in every node, and made a request to the master node 
of the cluster from some other machine in the network which doesn't belong to 
the cluster.

7. While the process being running (it takes some time to complete) deleted the 
EJB from master node to check the failover.
But the process stopped and it didn't failover.

8. By making several requests from seperate machines checked the loadbalancing; 
but only the master node's cpu gets busy. (That means no loadbalancing)

So what could be the problem?
  The way of making the request,
  The way of testing failover and load balancing
  or any other problem (my reference was "JBoss AS Clustering")
 
Please get us to the right track. (we have only few days)
