Navigation in JavaServer Faces, redirecting with correct parameters

Question

I have a page: http://mypage.com/items.jsf.

This page takes the following for granted:

• ID is set by GET or ID is set by POST.

Now, I can man

Answer 1

With only the core JSF framework and the Facelets library, you may find this difficult. The JSF 1.2 library does not include support for adding request parameters to the redirect URL.

A few solutions spring to mind:

• Just redirect as outlined here.
• Add your own custom NavigationHandler and/or ViewHandler code. Some 3rd party frameworks already cater for this type of thing. For example, Seam adds a pages.xml that allows parameters in navigation rules.
• Upgrade to JSF2. It adds support for handling parameters during navigation (and standardises Facelets as part of the core API, among other things - spec here). It's at release candidate 2, which may or may not suit.

Answer 2

If you are stuck with JSF1.2, you can also use the <h:outputLink> and nest <f:param name="" value=""> tags within it. The outputLink will include the parameters as query-params: ?name=value

If you need page-actions, navigation from methods, or jsut want to let an extension manage this for you, you can use PrettyFaces – SEO, Dynamic Parameters, Bookmarks, and Navigation for JSF / JSF2

It includes much simplified JSF navigation and linking.
