idea for struts actions

Many users have asked if there is a way to get security filter to
put more information in the session when a user logs in.  Also, you
might want to have custom messages and redirects for your
application.  There is an easy way to accomplish all of this.  You
simply have securityfilter forward to a struts action (or multiple
struts actions) to get the job done.  Here are a few snippets from
struts-config.xml

 <action-mappings>

     <!-- this is just a placeholder, it should never get hit, it is only
         to create the dynaformbean  -->
     <action path="/j_security_check" name="loginForm" validate="false" forward="/do/Login"/>

     <!-- this will run just after the j_security_check finishes with the request -->
     <action path="/Login" type="net.creativerge.struts.action.LoginAction">
         <forward name="failure" path="/loginError.jsp"/>
         <forward name="success" path="/index.jsp"/>
     </action>
 </action-mappings>

In my security filter config file I just set the login
success/failure pages to /do/Login

Then in my LoginAction class I just do the following

    if (request.getRemoteUser() == null)
    {
        // Login must have failed, put together some ActionErrors and go
        // whereever
        mapping.findForward("failure");
    }
    else
    {
        // we are logged in!  Go get information from the user and place
        // it in the session
        mapping.findForward("success");
    }

Now you can use the struts tags to make the login form and you can
execute an action.

The only thing I request is that we can adjust the pattern matched
for the login procedure so that any struts action extension can be
supported (ie *.do).
