@EJB annotation in entity bean does not work

Question

I just started with ejb3. I have created a couple of beans. One session bean that looks like this:
@Stateless
public class MySessionBean implements MySession
     @Resource(name="jdbc/mydb")
     private DataSource myDB;
public void someMethod() {
myDB.getConnection()
This works great. The other bean is an entity bean, and there the resource injection doesn't work. It looks like this:
@Entity
public class MyEntityBean
@Resource(name="jdbc/mydb")
     private DataSource myDB;
public void someMethod() {
myDB.getConnection()
Is resource injection any different in an entity bean then in a session bean? Both beans belong to the same package and are in the same application, (ear). I have exactly the same problem with @EJB injection: it works fine in the session bean but not in the entity bean...
Any help is appreciated...

<code>
@Entity
@Table(name = "assetfault")
@NamedQueries( {@NamedQuery(name = ... )})
public class Assetfault implements Serializable {
@javax.ejb.EJB private com.novadent.data.assetmg.sessionbeans.AssetFacadeLocal aF;
@javax.ejb.EJB private com.novadent.data.assetmg.sessionbeans.AssetfaultFacadeLocal afF;
</code>
importing javax.ejb.EJB ?
