Hi,
my standalone WebApp's didn't work with Tomcat. I have tracked it down
and found out Tomcat didn't initialize my Java Applications correctly.
The problem can be verifyed by the JSP Samples that came with Tomcat.
They work only partialy. The problem is Tomcat dosn't initialize servlet
jsp, they are unavailable.
Need Tomcat4 to be configured with Apache to ba able to use JSP?
Is there something in the CLASSPATH, two classes that bite each other,
the second overwriting the first, that could make the problem?
I have looked at all my clases on my system and installed Tomcat/Java on
a fresh installed one, same problem.
Maybe there is a class that should be moved somewhere so it could be
find, but which one and where?
Here is some debug output that may help:
