    jBPM-3.2.2 JBOSS-4.2.2.GA Clustering environment issue

    Deepak Sharma Newbie

      Hi,

      I am trying to setup the Clustering environment for the jBPM (jbpm-console.war).

      I have two nodes in the cluster. But when load balancer contacts the first node, an error is coming while browsing through the web application:

      It seems the NodeHashMap in the gravel-14.jar is not Serializable. And it clearly seen from the error that the value for this variable is put in the session.

      I would appreciate if some pointer could be given to resolve this error.

      Regards,
      Deepak

      Also my jboss-web.xml contains the following:

      <replication-config>
      <replication-trigger>SET_AND_GET</replication-trigger>
      <replication-granularity>SESSION</replication-granularity>
      <replication-field-batch-mode>true</replication-field-batch-mode>
      </replication-config>


      Error is following:
