Re: shared.loader classpaths
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.

What is the path of the file in WEB-INF/classes?
What is the name of the package+class of the class?

Do not do that. It's almost never necessary.

This is the correct way to do things.

Either the class files are not in the right place, or you are not
referencing them correctly.

I don't know of any version of Tomcat where the ClassLoaders didn't work
