    org.jboss.resteasy.spi.UnhandledException: java.lang.RuntimeException: Could not initialize stateful knowledge session: Could not connect task client

    Chaitanya Desai Newbie

      Hello Everyone,

      I am getting an exception when configuring jbpm 5.1 on jboss 5.1 with mysql 5.1.

      I have modified hibernate.cfg.xml, persistence.xml, testDS1.xml, jbpm-human-task-5.1.0.Final.jar and I am able to export the jbpm schema in my sql tables.

      4 new tables : eventtypes, processinstanceinfo,sessioninfo, workiteminfo got created into the database named jbpm_demo within mysql.

      However when i try to open the console i get the above exception.

       

      I think the exception is comming due to modifications required in jbpm-human-task-5.1.0.Final.jar . Did anyone face the similar exception (Exception stack trace @ bottom)

       

      Here is the information from the modified files @ the time of exception:
