[jboss-user] [EJB 3.0] - failed to deploy entity when persistence.xml is there

[peiguo]

I am trying out persistence and EJB 3, but I got this error when the jar is deployed:

  | 10:06:55,887 ERROR [URLDeploymentScanner] Incomplete Deployment listing:
  | 
  | --- MBeans waiting for other MBeans ---
  | ObjectName: jboss.j2ee:jar=order.jar,name=ShoppingCartBean,service=EJB3
  |   State: NOTYETINSTALLED
  |   I Depend On:
  |     persistence.units:unitName=sample
  | 
  | --- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
  | ObjectName: persistence.units:unitName=sample
  |   State: NOTYETINSTALLED
  |   Depends On Me:
  |     jboss.j2ee:jar=order.jar,name=ShoppingCartBean,service=EJB3
  | 
I do have a persistencein META-INF directory:

  | <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="sample">
  |       <jta-data-source>java:/DefaultDS</jta-data-source>
  |       <properties>
  |          <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
  |          <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
  |       </properties>
  |    </persistence-unit>
  | </persistence>
  | 
in my stateful bean I have this code:

  | package org.jboss.tutorial.entity.bean;
  | 
  | import javax.ejb.Remote;
  | import javax.ejb.Remove;
  | import javax.ejb.Stateful;
  | import javax.persistence.EntityManager;
  | import javax.persistence.PersistenceContext;
  | import javax.persistence.PersistenceContext;
  | 
  | 
  | @Stateful
  | @Remote(ShoppingCart.class)
  | public class ShoppingCartBean implements ShoppingCart, java.io.Serializable
  | {
  |    @PersistenceContext(unitName="sample")
  |    private EntityManager manager;
  |    private Order order;
  | 
  |    public void buy(String product, int quantity, double price)
  |    {
  |       if (order == null) order = new Order();
  |       order.addPurchase(product, quantity, price);
  |    }
  | 
  |    public Order getOrder()
  |    {
  |       return order;
  |    }
  | 
  |    @Remove
  |    public void checkout()
  |    {
  |       manager.persist(order);
  |    }
  | }
