Hi,

Am trialing the JPA aspects of Hibernate for a spike, but I'm having what I think are dependency problems.

The exact exception thrown is:

Exception in thread "main" java.lang.NoClassDefFoundError: org/hibernate/annotations/common/AssertionFailure
at org.hibernate.ejb.Ejb3Configuration.<clinit>(Ejb3Configuration.java:127)
at org.hibernate.ejb.HibernatePersistence.createEntityManagerFactory(HibernatePersistence.java:54)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:46)
at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:30)
[at user code]

I suspect that I'm missing a jar somewhere - most of the trouble I've had with Hibernate so far has been the depenedencies. Is there a clear matrix of what is needed somewhere? It all seems to be a bit of a mess in the maven repo.

I have this in my ivy.xml (I'm using Ivy and ant for build):

<!-- Hibernate dependencies for hbm.xml style -->
<dependency org="org.hibernate"
name="hibernate-core"
rev="3.5.1-Final"/>
<dependency org="org.slf4j"
name="slf4j-log4j12"
rev="1.5.8"/>
<dependency org="org.slf4j"
name="slf4j-api"
rev="1.5.8"/>
<dependency org="javassist"
name="javassist"
rev="3.4.GA"/>
<dependency org="javax.transaction"
name="jta"
rev="1.1"/>

<!-- Needed for JPA style -->
<dependency org="javax.persistence"
name="persistence-api"
rev="1.0"
conf="compile->default"/>
<dependency org="org.hibernate"
name="hibernate-annotations"
rev="3.5.1-Final"/>
<dependency org="org.hibernate"
name="hibernate-entitymanager"
rev="3.5.1-Final"/>
<dependency org="org.hibernate.java-persistence"
name="jpa-api"
rev="2.0-cr-1"/>

although I'm not completely sure I need both the javax.persistence and the org.hibernate.java-persistence dependencies (not that I think that's what's causing the problem).

Oddly, Eclipse is going to org.hibernate.AssertionFailure, not org.hibernate.annotations.common.AssertionFailure when I try to open the type referred to on the import line in AnnotationConfiguration.

Can anyone suggest which dependency I'm missing, or what the root cause of this bugbear might be?

Thanks,

Ben

Solved this issue (and recording here for posterity).

The clue was that the ClassNotFoundException was java.lang.ClassNotFoundException: org.hibernate.annotations.common.AssertionFailure - and that class only exists in Hibernate 3.3 - it's been changed to org.hibernate.AssertionFailure by 3.5

The issue was Eclipse, which bundles a version of Hibernate with it, which had got switched on, so was helpfully trying to provide some of Hibernate for me, and causing an impedance mismatch instead.

This was diagnosed by trying a regular command-line ant build instead, which immediately failed due to missing dependencies.

I'm having a similar issue. The error I am getting is...

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/applicationContext-hibernate.xml]: Invocation of init method failed; nested exception is org.hibernate.annotations.common.AssertionFailure: Declaring class is not found in the inheritance state hierarchy: com.cc.intrepid.model.RCMQuestionComment

Also using hibernate 3.5 only as far as i can see this has both

org.hibernate.annotations.common.AssertionFailure

and

org.hibernate.AssertionFailure

Did you manage to get yours to work in eclipse (I am using Websphere 7.0 which is built on eclipse)? If so did you manage to turn off the bundled hibernate?

Have kind of fixed this. The RCMQuestionComment class was annotated with @Embeddable, changed this to @Entity and it seems to work, just need to check out all relations and uses of this class to make sure they still work. Not sure why there was a problem though as we have other embeddable classes in the application.

If anyone knows any more about this can you please enlighten me? Thanks

This just happened to me when I changed an @Entity to an @Embeddable class; it was because I'd forgotten to remove its @Id variable.
