Do you have two copies of servlet.jar (or another JAR file that contains
servlet classes) elsewhere?  That would cause all sorts of classloader

: noclassdef found error for Sequence.

Be careful how you use the term CLASSPATH -- you don't set this variable
explicitly when you use Tomcat. Follow the guidelines and place JAR
files or classes under certain directories (e.g. {context}/WEB-INF/lib,
{tomcat}/common/lib, etc).

: classpath... I would be grateful for the info u provide... This problem is 
: bugging me since the past 2 days :-(

There's a classloader doc on the Tomcat website.
