If your Action class extends from Dyna Action Action, then
you can develop struts action class with out execute
method. Because in that action class we write our own
methods insted of execute method.
EXAMPLE:
public class Dispatch_Action extends DispatchAction
{
public ActionForward add(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception{
System.out.println("You are in add function.");
return mapping.findForward("add");
}
public ActionForward delete(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception
{
System.out.println("You are in delete function.");
return mapping.findForward("delete");
}
public ActionForward search(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception{
System.out.println("You are in search function");
return mapping.findForward("search");
}
public ActionForward save(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception{
System.out.println("You are in save function");
return mapping.findForward("save");
}
}
