[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Hibernate: failed if the models package in different JAR
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:
[java] javax.persistence.PersistenceException: org.hibernate.MappingException: Could not
determine type for: model1.User, for columns: [org.hibernate.mapping.Column(user)]
