Being a fan of the KISS policy... I played around with this but didn't have the time to figure it out, so I made the URL spat out by struts2 points to a servlet instead of struts2.
(Note that my web.xml has struts2 configured to listen for *.action rather then slash-star) Good luck & please let me know what your solution is.
