This will/may work with the JSDK2.1, but it doesn't appear to be a method
within JDSK2.0 (HttpRequest.setAttribute) - at least I didn't see it
browsing through Sun's API literature. I've never used the setAttribute
method, so I don't know too much about it.
If you can stand to place objects into your servlet engine's session, I
think that a good place to do it. Plus, if you are indeed using JSP pages,
you can make use of the Java bean architecture. If you can't, and are using
JSDK2.1, maybe setting the attribute in the Request object is a decent way
of doing it (?) One thing to keep in mind here is that (according to the
documentation, anyway), you could come into conflict when adding keys that
are JDK specific (like javax.*, java.* libraries).
