I just wrapped the request so that the request URI was something different. This was done in a filter. The request got passed down to struts and struts pulled out the new URI correctly and invoked the action. Once the action finished Struts tried to forward the request to the JSP and this is where it failed. The container was unable to perform the forward because the HttpServletRequest that was being passed to the request dispatcher had a different request URI and was a wrapper. Tomcat doesn't like that and was throwing some strange exceptions back. It was pretty simple. I just wrapped the request so that the request URI was something different. This was done in a filter.

I can't find any information online and the workaround you are using will not work for me since I need to have the wrapped request for the resource being forwarded to.
