    EJB calls loadbalancing

    Jaroslav Pavlicek Level 1

      Sirs,

      I call LiveCycle on JBoss 5.1 server (livecycle ES3 turnkey installation) using EJB API without problem on one machine.

      When in cluster, I would like loadbalance calls between two nodes. But I'm unable to do that. All calls are processes by same node. I use such a simple code:

       

      jndi.properties:

      java.naming.factory.initial= org.jnp.interfaces.NamingContextFactory

      java.naming.provider.url=node1:1100,node2:1100

       

      test.java:

      ...

      Properties connectionProps = new Properties();

      ServiceClientFactory myFactory = ServiceClientFactory.createInstance(connectionProps);

       

      HashMap<String,String> hmInput = new HashMap<String, String>();

      hmInput.put("a","10");

      hmInput.put("b","20");

       

      for(int i=0;i<5;i++) {

           InvocationRequest ir = myFactory.createInvocationRequest("tst/NewProcess1", "invoke", hmInput, true);

           InvocationResponse ires = myFactory.getServiceClient().invoke(ir);

           System.out.println("Result: " + ires.getOutputParameter("c"));

      }

       

      -------

       

      According to JBoss documentation (http://docs.jboss.org/jbossclustering/cluster_guide/5.1/html/clustering-jndi.html), there should be round robin implementation and calls should be processed by both nodes.

       

      Can you help me, please?

       

       

      Thanks,

      --- Jaroslav
