HibernateUtils.java is in classes folder.

JSP code is given below:

-------------
<%@ page language="java" import="net.sf.hibernate.*,net.sf.hibernate.cfg.*,net.sf.hibernate.examples.quickstart.*"%>

<%
Session session = HibernateUtil.currentSession();

Transaction tx= session.beginTransaction();

Cat princess = new Cat();
princess.setName("Princess");
princess.setSex('F');
princess.setWeight(7.4f);

session.save(princess);
tx.commit();

HibernateUtil.closeSession();
%>

The lib folder contains:
----------
cglib-2.0-rc2.jar
dom4j-1.4.jar
hibernate2.jar

Could somebody inform the changes to be made in the system configuration or the code?
