java.lang.NoClassDefFoundError: org/hibernate/mapping/MappedSuperclass

Question

Hi all,

Again, I am new to JPA & Hibernation. I am trying to use JPA technology in my web app. With the help of stackoverflow users, I have cleared many errors. With that experience and Confidence, I thought that I can do further myself. But, the current error is something different. I am not able to find it in google itself.

Its something looks like,

java.lang.NoClassDefFoundError: org/hibernate/mapping/MappedSuperclass

For your reference the list of errors & persistence.xml,

My IDE is eclipse, Hibernate as provider, using JPA 2.0.

Any Suggestions!!

Thanks!

Answer 1

Put hibernate on your class path. This will allow hibernate to be "found" when it is needed by your application. Here is a link to a short tutorial: Classpath in Eclipse

Answer 2

With JPA, Hibernate is not directly associated from your code. On Runtime though, the classes from Hibernate are still needed so you still need to put them on your classpath.
