Hibernate version: 2.1.7

Name and version of the database you are using:MySQL

J2ee server:Appserver of Sun

Hi,
I'm trying to use hibernate with j2ee and when I call the method buildsessionfactory, I get a classdefnotfound error. Here's a piece of the error:
Code:
Caused by: java.lang.NoClassDefFoundError
   at net.sf.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:796)



For completeness a larger piece of error:

Have you included all the libraries in the lib folder on your classpath?

Does it have to be in the lib folder, or is it ok that I just putted it in the classpath.
It is strange that the "Configuration" interface is loaded well although they are both in the same jar.

Well the stack trace that you posted doesn't tell which class exactly wasn't found. (It may not be the Configuration class). Try digging out the exact class that is not found. That the direction to head.

On the classpath is correct.
