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.....
