This sounds like a servlet engine problem - I have only done a little
servlet programming, and only with ServletExec & NES, but the worst we had
to do was restart NES to get ServletExec to restart which in turn got it to
recognize the new class. This was mostly because we were doing testing and
wanted to see the changes immediately. Often if we left it alone SE would
eventually recognize that a class had changed and load the new instance of it.
FWIW,
