Well, since your EjbLocator class is not itself a Service (Stateless EJB or
JMX), you can't inject into it. It's just a POJO; there's no way for the
container to know that it should be scanned for dependencies or injection.
So you can do one of a couple things:
1) Make your EjbLocator itself a
Can you explain a little more please?
In my EjbLocator class, I use
@PersistenceContext(unitName="StatInfoUnit")
private EntityManager manager;
public T find(Class ejb3Class, Object id) {
return manager.find(ejb3Class, id);
}
How should I do?
Caused by: java.lang.NullPointerException

Client injection is not supported in AS 4.2.

I reintroduce persistence.xml:
java:/StatInfoDS
META-INF/orm.xml
<*class>test.MySite
false
<*provider>org.hibernate.ejb.HibernatePersistence
<*properties>
<*property name="hibernate.hbm2ddl.auto" value="update" />
No I have followed your instruction, here is my code:
MySite.java:
package test;
@javax.persistence.Entity
@javax.persistence.Table(name="SI_SITE")
public class MySite {
@javax.persistence.Column(name="siteId")
@javax.persistence.Id
private java.lang.Long siteId;
@javax.persistence.Column(name
JF HEINTZ -
Are you also using @Inject instead of @PersistenceUnit? Post your code?

hi ALRubinger,the SessionBean just as follows
@Stateful
public class ShoppingCartBean implements ShoppingCart
{
@Inject
private EntityManager manager;
private Order order;
public void buy(String product, int quantity, double price)
{
if (order == null) order = new Order();
Could you post your code for the Session Bean?
S,

Don't install any of the preview release into AS 4.2. Use 4.2.1 as installed,
by default it has the latest EJB 3 installation.
