Hi,
I am trying to create a task and task instance at runtime, but always get the
following error :
Here is my Code :
public class Node1EnterActionHandler implements ActionHandler {
public void execute(ExecutionContext executionContext) throws Exception
{
// TODO Auto-generated method stub
System.out.println( "entered in Node1EnterActionHandler");
System.out.println( "exitting in Node1EnterActionHandler");
Token token = executionContext.getToken();
TaskMgmtInstance taskMgmt =
executionContext.getTaskMgmtInstance();
Task newTask = new Task("RuntimeTask");
TaskInstance taskInstance =
taskMgmt.createTaskInstance(newTask,token);
taskInstance.setName("RuntimeTaskIns");
taskInstance.setActorId("Shriram");
}
}
Iam not sure whether iam making any mistake.
If so plz giude me.....
