RE: Design Question - same action, many jsps/views

Mon, 28 Jul 2003 08:34:43 -0700

I used a design I called the "side trip action". Basically any caller to the action has placed, either in a form field or in the user session object, a "from" and "dest" url. the action does what it needs to do, redirects errors back to "from", and then forwards on success to "dest". I called this the "Side trip" because I originally used it for a small bit of "intelligence" -- you go to a page that requires you to be logged in.. you're sent to the login page.. and after a successful login, you're sent back to where you started from.

Hi Hue,

That's definitely one way to go, but the disadvantage that
I see of using this way is that you presumably have to hard code into
the action, some way of identifying where the request came from. Perhaps

something like:

String input = request.getRequestURI();

        if(input.equalsIgnorCase("inputpath1")
                return (mapping.findForward("page1"));

        else if(input.equalsIgnorCase("inputpath2");
                return (mapping.findForward("page2"));

        else if(input.equalsIgnorCase("inputpath3");
                return (mapping.findForward("page3"));


The previous new action mapping idea means you don't have to do
this I think, which might make it a better solution. What do you
think?

I'm not sure though, and thanks very much for the help.
Brian

Hi Brian,

Why not use different named forwards for the action and access each one
from
the action with a:

{
...
return (mapping.findForward("page1/page2/page3"));
}

In s-c:

<action path="/myAction"
  type="<FQ Class>"
  name="<bean>"
  ...
>
<forward name="page1" path="/page1.jsp"/>
<forward name="page2" path="/page2.jsp"/>
<forward name="page3" path="/page3.jsp"/>
</action>

Hue.
