Intercepting HttpRequests in portlet framework

Hi everyone !

I am using liferay bundled with tomcat for managing my spring mvc portlets ,
recently tried to add a filter to intercept all HttpRequests in order to perform some operation on them,
I tried with the basic method of adding a XML tag in the web.xml for the associated Servlet Class as we do in our servlet based web-apps, but that does not works.
I just need to intercept all HttpRequests at very first. Is it possible in portlet development ? .
I have already tried implementing RequestDataValueProcessor class provided by Spring, but the problem is,
any method(e.g processUrl() etc.) overridden to process the HttpServletRequest is invoked for as many times as there are portlets on the page,
i.e there is no single request here instead there are splitted requests for each portlet.

Can Anyone help ?
Thanks a lot in advance.

Thanks Wang, I need to study Oasis WSRP first.
Right now I just want to put things in the existing framework and I have not got the solution yet and still searching.
 
It is sorta covered in the JavaRanch Style Guide.
