Can anyone throw any light on the reason(s) for this exception? Obviously, the offending class is in the Hibernate3.jar, so it ought to be found. At the point at which the exception occurs the connection has been made to the DB. In fact, the app is almost at the point where it starts to execute.
The mapping file is below, as is the trace.
Thanks for your attention...

Hello Friend:

Please read:
http://www.hibernate.org/hib_docs/v3/re ... ation.html
1.2. Part 1 - The first Hibernate Application.

It indicate you which API's Jar you have to import or reference for ur application.

requests for comments.

I am getting the same exception at the same point. I am deploying my web app on Weblogic 9.1. From the console log it looks like it does connect to the database, but then right when it tries to either get a Hibernate session or access the EJB layer, I get this exception. I did look at the document referred to by neketsushonen, but did not really find anything that tells me about any jar files. Am I looking at the right document?

Thanks for any help.

Hi,

Do you have into your classpath all neccessary files? For example from your exception result that the cglib.jar is not in your classpath or there are some problems for loading that jar.

I hope this help
