Maybe you're not looking for the right thing...?

So far, I've been passing beans from JSP to a Servlet. I simply setup a bean in the
"request" context (it attaches to the request object) and then forward to servlet.
Servlet extracts it form the reqest with
bean = (OrgUnitBean)request.getAttribute( "bean" );

You're not saving that bean in any context, so it is created and lost after you do
forward. Just add that line I've added and it should be OK.
Nix.
