delegation exception
Hi all,
I have recently started using Jbpm. I am integrating struts with jbpm.
My processdefinition.xml looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<process-definition name="eAODemo">
<start-state name="start">
>
</start-state>
<task-node name="task1">
</task-node>
<task-node name="task2">
</task-node>
<end-state name="end1" />
</process-definition>
I get an error on taskinstance.end() in the following code:
jbpmSession=sessionFactory.openJbpmSession();
jbpmSession.beginTransaction();
Map taskParamMap = new HashMap();
taskParamMap.put("protocolId", new Integer(protocolId));
taskParamMap.put("requisitionId", new Integer(requisitionId));
TaskInstance taskInstance = jbpmSession.getTaskMgmtSession().loadTaskInstance(taskInstanceId);
Task task = taskInstance.getTask();
System.out.println("00000000000 taskInstance.getTask() 00000000000"+taskInstance.getTask().toString());
//TaskController taskController = taskInstance.getTask().getTaskController();
TaskController taskController = task.getTaskController();
System.out.println("99999999 taskController 99999999999999999"+taskController.toString());
taskController.submitParameters(taskParamMap, taskInstance);
jbpmSession.getGraphSession().saveProcessInstance(taskInstance.getTaskMgmtInstance().getProcessInstance());
jbpmSession.commitTransaction();
jbpmSession.close();
}
public void close(long taskInstanceId)
{
jbpmSession=sessionFactory.openJbpmSession();
jbpmSession.beginTransaction();
TaskInstance taskInstance = jbpmSession.getTaskMgmtSession().loadTaskInstance(taskInstanceId);
taskInstance.end();
jbpmSession.getGraphSession().saveProcessInstance(taskInstance.getTaskMgmtInstance().getProcessInstance());
jbpmSession.commitTransaction();
jbpmSession.close();
}
