[jboss-user] [EJB 3.0] - Re: EJB3: org.hibernate.type.SerializationException: could n

[D6L]

Hi,

the problem is that i don't have the permission to make changes on the DB because it's a LIVE/Production DB. So problems with releases/changes and so on. 
I tried to access now my attributs via @NamedQuery like this:
SELECT r.roadPK.origin.iata,r.roadPK.destination.iata, r.availabilityMethod FROM Road r

but there I got a compiler error:

Caused by: org.hibernate.HibernateException: Errors in named queries: Road.listAll
  | 	at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:397)
  | 	at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1327)
  | 	at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:867)
  | 	at org.hibernate.ejb.Ejb3Configuration.buildEntityManagerFactory(Ejb3Configuration.java:669)
  | 	... 75 more

By testing with 

SELECT r.roadPK.origin, r.roadPK.destination,r.availabilityMethod FROM Route r
i didn't get any error but also any output. lol Like i told it before, with SELECT r.availabilityMethod FROM Route r is no problem!

So logically I can access my attributs via r.roadPK.origin.iata but I get there the error! So I think that my mapping is wrong.
