Directly from Tomcat ...... no webserver involved. It's happening with the example
jsp files aswell - not my own code.
I'm assuming its some problem with servlet.jar.
Below is a sample from my logfile.txt. If you have time to look at it you'll be able
to see the exact errors I'm getting.
Thanks for all your help btw.
Caroline
