Class URIRedirectResolver

java.lang.Object
  com.taggercat.controller.URIRedirectResolver

All Implemented Interfaces:

RedirectResolver

public class URIRedirectResolver
extends java.lang.Object
implements RedirectResolver

This is the standard Redirect Resolver. It resolves a target response page and data state into an unique URI representation.

If we are dealing with a known response page, then we can use a re-direct to a bookmarkable URI as part of the POST-REDIRECT-GET (PRG) pattern.

Known response pages are those that have been configured in the metadata on the meta-entity objects. The meta data provides for specifying a Default Search Page, and a Default Edit Page. In our case, we also infer a default view page ( non edit scalar ) to be named in the same pattern as the Edit page.

The RedirectResolver works in conjunction with the FlashScopeRequestWrapper and the AbstractURIRequestHandler. This default implementation generates URIs for scalar and search views. A sub class can be installed to generate URIs of different structures.

When a redirect URI is generated, it is usually the URIRequestHandler that handles the subsequent redirect request. The Redirect URI ( path info ) for searching is patterned like:

 /Requirement/search/ctProject/21/ctPhase/4
 

The Redirect URI for the view (detail) and edit pages is as such:

 /Requirement/view/410 or 
 /Requirement/edit/410
 

You must add a context parameter to your application's deployment descriptor to register this class. See the Programmer's Guide for more detailed information.
