Added the below two lines to my filter (before the struts2 filter) in context2
app. That seems to do the trick. Thought it might create a problem as I am
setting a new ActionMapping in the request,
but seems to work fine. Do you see any side effects of this?
request.setAttribute("struts.actionMapping", new ActionMapping());
request.setAttribute("struts.valueStack", null);
Thanks,
Prasanth
