nested exception is java.lang.NoClassDefFoundError: org/hibernate/ejb/HibernatePersistence

Question

I\'m trying to configure Spring 3.2, JPA 2.0 with Hibernate 4 as the persistence provider. When I try to deploy the application in Weblogic 10.3.5, I get the following erro

Answer 1

Since you get a java.lang.NoClassDefFoundError (and not a ClassNotFoundException), it's probably some sort of classloading issue.

It's often caused by importing in the webapp librairies (WEB-INF/lib), JARs that are already available in the application server.

In your case, I suspect hibernate-jpa-2.0-api.jar.

Here's two things to try :

• Exclude hibernate-jpa-2.0-api.jar from your dependencies.

  OR

• Add in the weblogic.xml file.
