tracking user activities: how to ignore action chaining (or server side forward)

Hi,
 I am writing a RequestProcessor that is a subclass of
Struts 1.1 RequestProcessor, the purpose is to track
user activities, i.e. which link the user clicked,
which page the user requested etc.
 I override the method processForwardConfig, and put
my tracking function first, here is how it looks:

//my code to log user request
logPage(request.getRequestURI());
super.processForwardConfig(request, response, forward
);


 However, there is one problem with this approach, 
If there is action chaining (or server side forward),
that will be also logged, but that is not the user
requested URI, and I don't need to log any of chained
action URI or server side forwarded URI. 

 Any suggestion how to deal with this problem?

Thanks.
David

Re: tracking user activities: how to ignore action chaining (or server side forward)

Posted by Kris Schneider <kr...@dotech.com>.
Sorry, filters were introduced in Servlet 2.3. What you might try doing is using
a request attribute as a flag to indicate that you've already logged the
requested URI. Maybe something like:

if (request.getAttribute(MyConstants.URI_LOG_FLAG) == null) {
  request.setAttribute(MyConstants.URI_LOG_FLAG, Boolean.TRUE);
  logPage(request.getRequestURI());
}
super.processForwardConfig(request, response, forward);

If you get the chance to move to a Servlet 2.3 container, filters will work just
fine in combination with Struts.

My company using Websphere 4.0.5, and it only supports
servlet 2.2. Does filter only operate on the original
client request for servlet 2.2 also? Can filter works
well with Struts actionservlet?

Thanks.
David

Absolutely. One place to start would be Sun's own J2EE 1.3 Tutorial:

http://java.sun.com/j2ee/tutorial/1_3-fcs/index.html

Specifically, there's a section called "Java Servlet Technology":

http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/Servlets.html

Also, the Servlet 2.3 Specification is the definitive guide and it's not 
that bad a read:

http://www.jcp.org/aboutJava/communityprocess/final/jsr053/

And there's always the Servlet home page itself:

http://java.sun.com/products/servlet/

Seems like the easiest thing to do would be to write a Filter mapped to "/*"
that uses HttpServletRequest.getRequestURI to capture the requested URI. In a
