RE: newbiew Q: how to do redirect instead of forward

[Brandon Goodin]

1) You need to set your forward redirect="(true|false)" in your
struts-config.xml for that particular action mapping.
2) The difference...
a) "redirect" generates a whole new request by sending a header back to the
client you lose all of your request scope data.
b) "forward" continues with the same request and arrives at the view with
request object intact.

RequestDispatcher vs response.redirect();

This is probably a silly question, but what's the difference between
forward and redirect?

Subject:  newbiew Q: how to do redirect instead of forward



for forward we usually do
execute() {
    ...
    return mapping.findForward("listing");
}

I tried to use redirect by
execute() {
      ActionForward af = mapping.findForward("listing");
      af.setRedirect(true);
      return af;
}

but get exception
