I've only used chaining for filtering. There is now a Filter interface that is supposed to replace this technique. I haven't used the interface yet, though.
Still, chaining is fun

This is one area of Servlets I wish I had more exposure to.
I can envision a lot of neat ways to manipulate content input and system output.
FYI - I'm trying to use multiple J2EE servers as I go through the Drive. It's helpful as I develop my own code too. I have Tomcat, Orion, WebSphere and WebLogic on my laptop. There is a big difference between the front-end interfaces. It's kind of neat to see how each one tackles the same problems.

To Pauline:
A request is sent to the server, a first servlet is called but you told the server to always, or dependent on a condition (mime-type), a second (or more) servlet should use the output of the foregoing one as input ==> chaining, and you call it filtering
if e.g. a servlet outputs a table in raw form
(e.g. start table of three columns with header,
the lines of a table, end table) and a follow up servlet adds the necessary html code such that the client browser renders the output as nice html -table. ...
