7:20 p.m.
I could not find a solution in the forum for this, sorry if this is a redundant question.
I just upgraded my existing app to use Seam 2.0 Beta, after the upgrade I am having
problem getting the hibernate Session using entitymanger.getDelegate(). This is working
perfectly in Seam 1.2.1.
My Components.xml
<persistence:managed-persistence-context name="entityManager"
auto-create="true"
persistence-unit-jndi-name="java:/myAppEntityManagerFactory"/>
|
| <factory name="session" scope="STATELESS"
auto-create="true" value="#{entityManager.delegate}"/>
@In
| private EntityManager entityManager; //Seam Managed Persistence context, declared in
components.xml
|
| @In
| private Session session; //factory declared in components.xml
|
| DetachedCriteria dc = DetachedCriteria.forClass(getEntityBeanType());
| for (Criterion c : criterion) {
| dc.add(c);
| }
| Criteria crit = dc.getExecutableCriteria(session);
| return crit.list();
I am getting the follwoing exception:

As mentioned earlier, this is working without any issues in Seam 1.2.1 GA. It is not
working in Seam 2.0 Beta. Am I missing something here, do I need to do any special
declarations in components.xml for the session. I appreciate if somebody can help me on
this.
BTW: I tried something like this as well, but same result.
//Session session = (Session) entityManager.getDelegate();
