    ClassCastException when using RoundRobinRouterFactory

    Henrik Bentel Newbie

      Hi

      I've got JBM 1.2.0.sp1 running in JBoss AS 4.2.0.CR2
      I've setup a 2-node cluster and all the JBM examples runs fine, including the cluster ones.

      Now I'm trying to set up round robin routing using the instructions at
      http://labs.jboss.com/file-access/default/members/jbossmessaging/freezone/docs/userguide-1.2.0.GA/html/c_configuration.html#clusterrouter

      But when the server starts up I get a ClassCastException (stacktrace below)
      The only configuration I changed to enable round robin was setting the ClusterRouterFactory attribute for the ClusteredPostOfficeService, per the instructions.

      I'm guess I'm missing some configuration.

      hope someone can help
