Hi Bobo:
I had a similar problem, where my servlet would compile fine (so obviously it
found the class ok you would imagine), but at run-time the dreaded
"NoClassDefFoundError" would occur. (Note that is different from the
ClassNotFound error!). After searching a lot on Google, the general Java
archives,etc., I read accounts where other people had this same error. Some
people even said Tomcat doesnt pay any attention to what you say your classpath
is. (I don't know how much truth there is in this claim, nor why this should be
so..) However, in desperation I finally placed my jar file in
/usr/local/jakarta-tomcat/lib, restarted the tomcat engine, and my servlet ran
fine then. You may try something like this at the appropriate place in your set
up.. Sorry I don't have a more intellegent response, but maybe this will help.
Good luck!
Geeta
