Error using Oreilly's packages...?

SUBJECT: Error using Oreilly's packages...?

I have my Java Servlets under /local/tomcat/webapps/hari/WEB-INF/classes

My Java Servlets use Oreilly's predefined classes and I use that so as not to reinvent the wheel.
Oreliiy's classses are avaliable as "cos.jar" file and when I unjar them I get following structure
com/oreilly/servlet/*.classes

I have stored this cos.jar file under "/local/tomcat/webapps/hari/WEB-INF/lib/" and "/local/tomcat/webapps/lib/"and have these on my CLASSPATH.

In my Java Servlets, I do following import
-------------------------------------------------
import com.oreilly.servlet.MultipartRequest;
import com.oreilly.servlet.*;
-------------------------------------------------

It compiles everything fine BUT when I run my WEB APPLICATION (http://us.hari.com/hari/BatchUpload1) it gives my following ERRORS wonder why...
------------------------------------------------------------------------------- -
description: The server encountered an internal error () that prevented
it from fulfilling this request.
exception

javax.servlet.ServletException: Error instantiating servlet class
util.BatchUpload1
at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:865)
....
root cause

at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.java:856)

Can anyone point what is wrong here.,..

Sincerely,
