Hi all geeks and nerds!

  I have been working on apache-tomcat 5.5.20 version and trying to execute a simple servlet program that would accept few GET parameters and do some stupid stuff at 'respose'.

  But now I have been getting an exception 'ClassNotFoundException' for some weird reason when I try to debug my application on server. Here I paste a log of that:

 As far as I perceived it's a problem loading the 'webapp' or 'lib' .class files for execution, if I m not much wrong. What could go wrong in my application? All other applications work simply well!

 Any ideas or previous encounters of same exception in same context! Please post your opinions too!!

ClassNotFound Exception means that the class that the container has been trying to load is not available in its classpath or the application classpath.
I guess Article is one of your class? If that is correct, would you check if you have placed the class in proper application folders WEB-INF\classes directory? With proper directory structure as of that package?
