But you don't have to create any classes to provide an action path abstraction for a JSP page. There are (at least) a couple of built-in ways to do this:
1:
<action-mappings>
<action path="/welcome"
forward="/WEB-INF/jsp/welcome.jsp"/>
</action-mappings>
2:
<action-mappings>
<action path="/welcome"
type="org.apache.struts.actions.ForwardAction"
parameter="/WEB-INF/jsp/welcome.jsp"/>
</action-mappings>
In both cases, "/do/welcome" gets you to "/WEB-INF/jsp/welcome.jsp". If
you decide later that "/do/welcome" should take you some place else, or
you need to interpose an action into the request processing, all that
changes is the action definition in your config file. The client
interface to the app doesn't change, it still uses "/do/welcome". To my
mind, this is the way to establish the separation between interface and
implementation for web apps.
As to the poster's original question ;-), I have no idea why it's not
working. I've made extensive use of both approaches under 1.0.2 without
a problem.
