[jboss-user] [JBoss jBPM] - cannot be cast to org.jbpm.graph.def.ActionHandler

[AJanz]

i got a simple class implementing the actionhandler.

but when i try to execute it i got 

WaitAndSignal cannot be cast to org.jbpm.graph.def.ActionHandler

code is


  | 
  | import org.jbpm.graph.def.ActionHandler;
  | import org.jbpm.graph.exe.ExecutionContext;
  | 
  | 
  | public class WaitAndSignal 	 implements ActionHandler{
  | 
  | 	 private final static long serialVersionUID=1l;
  | 	 
  | 	 public void execute(ExecutionContext executionContext) throws Exception {
  | 		// TODO Auto-generated method stub
  | 		try { 
  | 		System.out.println("Begin WaitAndSignal");
  | 		long dauer = System.currentTimeMillis()% 100000;
  | 		Thread.sleep(dauer);
  | 		executionContext.getProcessInstance().signal();
  | 		System.out.println("pid is = " +executionContext.getProcessInstance().getId() );
  | 		}
  | 		catch(Exception e  ) {
  | 			e.printStackTrace();
  | 		}
  | 		System.out.println("end WaitAndSignal");
  | 
  | 	}
  | 	
  | 	int wait =100;
  | 
  | 	public int getWait() {
  | 		return wait;
  | 	}
  | 
  | 	public void setWait(int wait) {
  | 		this.wait = wait;
  | 	}
  | 
  | }
  |
