Re: Dealing with Struts Forwards

From the posts I have been reading in this forum, forwards can only be decorated if you are using a 2.4 container i.e Tomcat 5.x.  As this is not possible for me is there any other work around besides using the calling url to perform the mapping to a decorator?  I cannot use redirect=true as there are request attributes that are required in the results page.  Also

The behaviour of forwards was not clarified until the 2.4 spec.  Some 
containers (Orion) allowed decorators to be applied around every 
forward, while other containers only allowed them at the top level.

However, you could probably write a DecoratorMapper similar to the 
ConfigDecoratorMapper, which instead of using the 
request.getRequestURI() uses the request attribute 
"javax.servlet.include.request...." (sorry - offline - can't look it up).

The request attribute contains the URI of the forwarded or included 
page, and you could use that instead.

Let me know how you go.

Scott
