If an example of a ContextListener would be helpful, and perhaps even
something that will do the trick for you, depending on the requirements,
take a look at the code I just checked in to CVS for JavaWebParts:
http://sourceforge.net/projects/javawebparts/
It is available in HEAD. I added a ContextListener that reads in an XML
file and exposes it in a bean (either a default simple bean or your own
custom job). If by chance the data you need can be stored in an XML
file and not tied to a session, this might do the trick for you. And
even if it isn't appropriate, it should at least be a working example of
a listener for you.
Actually, an interesting thought... if you took my listener and made
your XML file just name the table to query, you could still read from a
database... create a custom bean with a setter that matches the element
in the XML file, and instead of just setting a class field, do the
database read and whatever else. Not how I envisioned it being used,
but I think it should work.

Wendy, can you please give me the complete class name of that Listener
object? Is it referenced in the web.xml??
Thanks, Alex.

I need to store some objects in session scope in order to use
around the application.
If you need to use them across the entire webapp, then application/context
scope might be more appropriate. But either way, what I do is have a
Listener that is notified when the app (or a session) starts. I put
various
Maps and Lists into the appropriate scope under known keys, and then
they're
there to be used whenever I need them.
Take a look at HttpSessionListener or ServletContextListener depending on
what you decide you need.
