[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - Hibernate 3/Spring DAO objects and Spring Http Remotly throw

[J0Ke]

Im using Hibernate 3 
and have Spring Dao objects using getHibernateTemplate().
the problem is when i try to call findAll() method of a DAO that return objects which have Sets of related Objects from child tables. i get : 
org.springframework.remoting.RemoteAccessException: Cannot access HTTP invoker remote service at [http://localhost:8080/DiplomnaHibernate/remoting/SubjectauthorityDAO]; nested exception is java.io.InvalidClassException: org.hibernate.collection.AbstractPersistentCollection; local class incompatible: stream classdesc serialVersionUID = 7602608801868099635, local class serialVersionUID = -5723701046347946317

at : 
        ApplicationContext  springContext = new ClassPathXmlApplicationContext("beans.xml");
        SubjectAutorityBean relSubjectsBean=(SubjectAutorityBean) springContext.getBean("subjectAuthorityDAO");
        
        List subjects=relSubjectsBean.getDao().findAll();

if i make relSubjectsBean.save(......); the save works but findAll not work
if i have a plain table with a dao bean not related to anythink it works

I have :
