Trying to inject a Hibernate Session with @PersistenceContext fails:
anonymous wrote :
| java.lang.ClassCastException: $Proxy1497 cannot be cast to
javax.persistence.EntityManager
The reason for this was pretty obvious once I took a look at the code of
org.jboss.seam.intercept.SessionBeanInterceptor:
| ...
| //wrap any @PersistenceContext attributes in our proxy
| for ( BijectedAttribute ba:
getComponent().getPersistenceContextAttributes() )
| {
| EntityManager entityManager = (EntityManager) ba.get(bean);
| if ( ! (entityManager instanceof EntityManagerProxy ) )
| {
| ba.set( bean, new EntityManagerProxy(entityManager) );
| }
| }
| ...
|
Apparently it doesn't even look at the field type, and always assumes that I
want to inject an EntityManager. Even if I do inject an EntityManager, then
#getDelegate() won't give me a Session, as it would without Seam. How the heck
do I directly inject a Hibernate Session??
