[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Hibernate: failed if the models package in different JAR

[ericmacau]

Hello,

I create some models in Hibernate (with Annotation and EntityManager).

If I packed them into one JAR, everything is fine.
If faield if I packed them into two JARs.

For example,

model1.User  <<<< mode1.jar

model2.Phone <<<< model2.jar

class Phone {
   private String no;

   private User user;
}





Both JARs(mode1.jar and model2.jar) will be in the same class loader, but when I run a client, it just throws the following exception:
