RE: newbiew Q: how to do redirect instead of forward
Try building the whole forward from scratch.
ActionForward forward = new ActionForward();
forward.setPath(/newrequest/index.jsp);
forward.setRedirect(true);
forward.setContextRelative(true);
return forward;

RE: newbiew Q: how to do redirect instead of forward
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();

Re: newbiew Q: how to do redirect instead of forward
b) plus the addressbar doesn't change.
this sometimes causes problem, for example starting from a fowarded page,
you go to another webpage, then go back you will not get the same page.

RE: newbiew Q: how to do redirect instead of forward
When you redirect, the RequestDispatcher tells the browser to request
another URL. When this happens there is always a round trip to the client
side and the previous Request and Response objects are lost. Also, redirect
allows you to request a resource outside the current application.
In a forward, the request is done w/o the help of the client browser. Also,
the Request and Response objects are kept.

RE: newbiew Q: how to do redirect instead of forward
Ok. So, from the user's perspective, when we do a redirect, they are sent
to a different location. When we do a forward, they are not, even if the
content changes?

Ok. So, from the user's perspective, when we do a redirect, they are sent to a different location. When we do a forward, they are not, even if the content changes? The content changes to the content of the new page, but address bar stays the same because all the forwarding is done on the server side. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

So, from the user's perspective, when we do a redirect, they are sent to a different location. When we do a forward, they are not, even if the content changes? You've got it. Essentially, the URL that is requested addresses a piece of business logic (save this customer or search this database) -- it has nothing at all to do with which page actually produces the output. Internally, the application implements this with a RequestDispatcher.forward() call, which is essentially like calling a subroutine -- the client has no clue who really provided the response. I'm something of a rebel in this regard, but I believe that the location bar and the back button are the two worst features of HTML browsers. In a Model 2 design architecture like the one that Struts advocates, URLs are basically irrelevant to users -- it's just a feature of the plumbing used to enable the application to execute. I've also been known to create web applications that open the app in a new window without these things -- it doesn't stop the advanced user who knows the keyboard shortcuts from trying to screw things up, but it sure cuts down on the unsophisticated users who think a web application is supposed to be browsable the same way that a web site is :-).
