Hi,
I have a problem implementing EJB session bean with Hibernate.
My web app is implemented in Struts 1.1. The LoginAction is invoked and
it succesfully looks up the HibernateTestHome, creates a remote interface
and calls doService() method that prints out success message indicating
that the session bean was succesfully looked up and created.
If I add Hibernate related code, I get an error message.
I need to mention that I have followed first 6 steps described in the
"Cookbook for running Hibernate in IBM WSAD 5.x" at
http://forum.hibernate.org/viewtopic.ph ... e+wsad+5+x
I did not setup DataSource and JAAS athentication becouse I would like to
use the info from hibernate.properties file.
My LoginAction looks like this:
package com.cot.ewwcms.web.struts;

public ActionForward execute(

}
and my HibernateTestBean looks like this:

Why is it that the "java.lang.NoClassDefFoundError: net/sf/hibernate/cfg/Configuration" is happening when I have setup all the configuration according to the above article.
Pleas help!
