how to set findForward for specific module action?

Question

public class TestAction extends Action 
{ 
 public ActionForward execute( 
   ActionMapping mapping, 
   ActionForm form, 
   HttpServletRequest request, 
   HttpServletResponse response) throws Exception{ 
     return mapping.findForward("test"); 
 } 
} 

... A developer attempts to use an ActionForward by calling mapping.findForward("test"). However, the Struts application contains the same forward mapping name in two different modules (called modulex and moduley). Referring to the above, how does the developer specify the "test" forward in "modulex"?
