Servlet Chaining

Can anybody give me a good definition of Servlet Chaining along with an example, links to sites with this info are also welcome.
Thanks in advance.

The term "Servlet Chaining" is out of date now. You should be looking for information on the Filter and FilterChain APIs and for RequestDispatcher forward and include processes.

Maybe, but the term is still relevant. Typically a request comes in for a servlet, that servlet executes and pushes out a response, perhaps via a JSP. Servlet chaining is just used to describe the process whereby a servlet will do some work, then hand off processing to another servlet and so on. This is generally done with the RequestDispatcher include() and forward() methods.
Even though many people now use web application frameworks such as Struts and WebWork, you can still achieve the same result by chaining together actions.

hiiii,
well in serv chaining we configure the servlet engine to do the chaining.During setup we specify the order in which these servlets are invoked.nad this non standard feature is not supported by most of the web containers today.
ok

Which internally will have the framework chain servlets together as likely as not
