Hi

I was trying to get the hibernate sample program running with Annotations. I got sample working fine when it is executed with a *.hbm.xml file. I minimized the usage of hbm.xml file. I get a error as mentioned below. Please check out the error and suggest me how to make it working.

Results with an error :

INFO [Configuration] Configured SessionFactory: null
ERROR [STDERR] Initial SessionFactory creation failed.java.lang.ClassCastException: org.hibernate.validator.event.ValidateEventListener
INFO [[/Hibernate_with_Annotations]] Marking servlet createServlet as unavailable
ERROR [[createServlet]] Allocate exception for servlet createServlet
java.lang.ClassCastException: org.hibernate.validator.event.ValidateEventListener at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:819)

Hi there

In the Hibernate Annotations documentation it says that you should use the fully qualified path name with the addPackage method. Is "events" the fully qualified name?

Might not be the solution but couldn't hurt to check.

Other questions are - what version of Annotations are you using and are you using this with JBoss?

Cheers,
Rachel

Let me little a bit clear with my doubt

Is Hibernate possible without the help of *.hbm.xml files ? If so how to get that done ? any samples please.
I am really tired on heading to solve this doubt.

Yes, you can use annotation if you do not want to use hbm.xml file. Please refer to this link for more information of annotation
