Answers to the questions below...
I spent 10 hours on it so far, so I've tried many things. Now I did see
the Action errors listed in the JSP. Either Struts is not putting the
form bean on the request/session, or it's not populating what it did put
on the request/session with was it found in the submitted form bean.

I have tried both session and request, and neither worked, though it
shouldn't matter which one you choose, no?
