I am trying to test an Stateless bean with JUnit in netbeans. This bean uses an EntityManager.
@Stateless
public class myEjb{
@PersistenceContext
private EntityManager em;
public MyResult getResult(){
return em.find(...);
}
}
Then I write a test class.
public class myTest{
private static EJBContainer ec;
private static Context ctx;
@BeforeClass
public static void setUpClass(){
ec = EJBContainer.createEJBContainer();
ctx = ec.getContext();
}
....
}
When I run the test, it does not work. I obtain the following message: Invalid resource : mydb__pm The error occurs when this line is executed:
ec = EJBContainer.createEJBContainer();
If a change my bean by removing the entity manager, it works. So, it seems that I have a problem with the entity manager. My persistence.xml file is simple:
<persistence version="2.0" ...>
<persistence-unit name="MetisDemoPU" transaction-type="JTA">
<jta-data-source>MyDb</jta-data-source>
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties/>
</persistence-unit>
</persistence>
Finally, I create a JSF managed bean that called my EJB (which uses the entity manager) and it works.
@ManagedBean
@RequestScoped
public class myManagedBean{
@EJB
private OfferEjb offerEjb;
...
}
Any help would be appreciated!
