[jboss-user] [EJB/JBoss] - Re: Classloader nightmare and ClassCastException. Isolatio

[tnine]

Well, I found a work around by following the formula from the previous post.  I was getting the following exception at the bottom of my trace.  I accidentally posted the wrong section in my earlier post


  | Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'hibernateSessionFactory' defined in class path resource [statements-mdb.xml]: Invocation of init method failed; nested exception is java.lang.ClassCastException: org.hibernate.validator.event.ValidateEventListener

So, I went digging for what project the class org.hibernate.validator.event.ValidateEventListener is a member of.  Its used in the hibernate validator project.  I added the hibernate-validator jar version 3.3.0.ga to my MDB's dependencies.  As soon as I deployed with this additional jar, my issue was solved.  I'm still not sure why Hibernate was trying to load this class, since I don't need it to perform my integration testing.  Hopefully this will help someone else out!
