    CommunicationException when looking up EJB (SLSB 3.0)

    Shreyas Shinde Newbie

      Hello,

      When looking up an SLSB (EJB 3.0) I am getting a CommunicationException in JBoss 5.0

      javax.naming.CommunicationException: Failed to connect to server 10.14.51.52:1100 [Root exception is java.lang.ClassCastException: java.util.Collections$UnmodifiableRandomAccessList]


      The properties used in the InitialContext are:
      java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
      jnp.discoveryGroup=230.0.0.4
      jnp.discoveryPort=1102
      jnp.discoveryTimeout=5000
      jnp.disableDiscovery=false
      jnp.partitionName=ClusterOne



      Can you tell me what could I be missing? Any pointers would be appreciated..

      Thanks,

      Shreyas


      Platform: RHEL4
      JBoss AS 5.0
