IllegalMonitorStateException: current thread not owner

[kay lin]

Hi All:
In my UpdatePayeeAction (it extends Action btw), I have the followinng line

 
public ActionForward execute(ActionMapping mapping,
                               ActionForm actionForm,
                               HttpServletRequest request,
                               HttpServletResponse response) throws Exception {
 

        //codes omitted
 
        System.out.println("multiple submits");
           wait(3000);
    
      }
  

and then i got

java.lang.IllegalMonitorStateException: current thread not owner
at java.lang.Object.wait(Native Method)
at com.sunlife.dx.paymentinquiry.struts.inquiry.UpdatePayeeAction.execute(UpdatePayeeAction.java:154)

So my question is can i actually put the wait() in the execute method? if i want the execute() to pause a little bit,
because i want to pause a bit before the execute methods returns a response through ActionForward, how should I do
that correctly,

Please let me know...
