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:

Thanks, but my point was that they're really nothing alike. I wasn't asking the questions because I didn't know the answers, I was asking because the answers would illustrate some of the differences. If the information in the link you provided implies that event listeners and filters are almost the same thing then it's horribly misleading.

Hi Kris,
I have studied eventlisteners in a book[programming jakarta struts].I think below mentioned url will provide u with the required info..

Thanks Prashanth

Quoting "Prashanth.S" :
I think u can also use eventlisteners which are allmost same thing as filters.. Regards Prashanth

Quoting david chan :
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
