Thank you Chris, for keeping on the problem. I don't know if you saw the last mail sent by me to the list.
The thing was resolved by placing all the JSP referencing those classes at the web root folder. I did that, and it worked. That's why I hung my solution in the list. Nevertheless, Mark Thomas told me I was wrong. What I supposed that was the problem, and the solution was wrong. He told me JSPs may go everywhere in the folder structure. And asked me for giving a simple example of my error. Anyway, by then my app worked already, so I put off to make the example until today. And certainly, I can't reproduce it. Mark is right, of course. I am new in all this. Now, my last chance to have the example is starting from a new copy of what is now going on, recover the old hierarchy of JSP ant try to reproduce the error. I am in Thanks again for you help, Chris.
