    failed to deploy entity when persistence.xml is there

      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 ---

       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);
       }
      }
