help: config filter-mapping and struts

[c tang <cc...@yahoo.com>]

Hi all,

I wrote an app using struts and it works fine.  Now I
want to add a filter, so that a pre-defined page will
be filtered before return.  The question is how to
specify <filter-mapping>.  I tried lots of options, it
does not work.

For the following action,

 <action    path="/generateBig"
            type="GenerateBigAction"
            name="form"
            scope="request"
            input="/get.jsp"
            validate="false">
      <forward name="success"  path="/success"/>
 </action>

I want to compress the response when it is forward to
success page(/success).  When I map filter to
generateBig.do, the doFilter method is invoked, but
the request page is returned.  Even if correct page is
return, I think mapping to generateBig.do is not the
right way because failure page will be filter too. 
When I map filter to /success(or the servlet mapping
to /success), the doFilter method is not even invoked.


please help!
