Tomcat 4.1.18 .................. WEB-INF\classes problem

Question

I am using Tomcat 4.1.18 and working on JSPs. I have written a JSP that calls a Bean located in WEB-INF\classes. When I make a POST call to the JSP I get the following error

The server.xml has the following context.
     <Context path="/techsupport" docBase="techsupport" debug="0"
reloadable="true" crossContext="true">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_techsupport_log." suffix=".txt"
     timestamp="true"/>     
     </Context>
==============
Can somebody tell me where I went wrong? I think some configuration is missing especially CLASSPATH but am using the default CLASSPATH and the
webapps/examples is working fine.
My program is located at webapps/techsupport folder.
Thanks.
