Upon initialization of a SLSB in WebSphere 7.0 I get the following exception:
Code:

The bean looks like:
Code:
@Stateless
@Remote
public class TestBeanEJB implements TestBean {
@PersistenceContext(unitName = "Test")
private Session session;
public String ping() {
return "pong";
}
}
my persistence.xml looks like:
Code:
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">
<persistence-unit name="Test">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>jdbc/MyDS</jta-data-source>
<properties>
<property name="hibernate.show_sql" value="true"/>
<property name="hibernate.dialect" value="org.hibernate.dialect.SQLServerDialect"/>
<property name="hibernate.hbm2ddl.auto" value="update"/>
<!-- WebSphere transaction manager lookup class -->
<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.WebSphereExtendedJTATransactionLookup"/>
</properties>
</persistence-unit>
</persistence>
The application is packed as an ear with an ejb-jar containing the bean. There are no exceptions during application installation/startup and Hibernate initializes without any errors.
I'm using WebSphere 7.0 + Fix pack 1.
Why does the injection engine try to inject a JPATxEntityManager and not a Hibernate session here?
