[jboss-user] [EJB 3.0] - persistance.units NOTYETINSTALLED

[z3r0]

Hi,

I use JBoss 4.0.5 (with EJB3 support) and I develop with Eclipse 3.2.1/WTP 1.5.2.
I try to deploy EJB3s under JBoss, but I'm not abble to access to the persistance manager.

My first EJB Session Stateless runs well :

HelloService.java :
package com.test.jboss.ejb3;
  | 
  | import javax.ejb.Local;
  | 
  | @Local
  | public interface HelloService {
  |    public String hello(String name);
  | }

HelloServiceBean.java :
package com.test.jboss.ejb3;
  | 
  | import javax.ejb.Stateless;
  | 
  | @Stateless
  | public class HelloServiceBean implements HelloService {
  |    public String hello(String name) {
  |       return "Hello " + name + " ";
  |    }
  | }

This EJB is correctly deployed in JBoss and I can call it form my web module.


My second EJB Session Stateless which use EJB Entity don't run well :

Contact.java :
package com.test.jboss.ejb3;
  | 
  | import javax.persistence.Entity;
  | import javax.persistence.GeneratedValue;
  | import javax.persistence.GenerationType;
  | import javax.persistence.Id;
  | import javax.persistence.Table;
  | 
  | @Entity
  | @Table(name="contact")
  | public class Contact {
  | 	@Id
  | 	@GeneratedValue(strategy=GenerationType.AUTO)
  | 	private int id;
  | 
  | 	private String name;
  | 
  | 	public int getId() {
  | 		return id;
  | 	}
  | 
  | 	public void setId(int id) {
  | 		this.id = id;
  | 	}
  | 
  | 	public String getName() {
  | 		return name;
  | 	}
  | 
  | 	public void setName(String name) {
  | 		this.name = name;
  | 	}
  | }
  | 

ContactService.java :
package com.test.jboss.ejb3;
  | 
  | import java.util.Collection;
  | 
  | import javax.ejb.Local;
  | 
  | @Local
  | public interface ContactService {
  |    public Collection<Contact> findAllContact();
  | }

ContactServiceBean.java :
package com.test.jboss.ejb3;
  | 
  | import java.util.Collection;
  | 
  | import javax.ejb.Stateless;
  | import javax.persistence.EntityManager;
  | import javax.persistence.PersistenceContext;
  | 
  | @Stateless
  | public class ContactServiceBean implements ContactService {
  | 	@PersistenceContext(unitName = "testdb")
  | 	protected EntityManager em;	
  | 
  | 	@SuppressWarnings("unchecked")
  | 	public Collection<Contact> findAllContact() {
  | 		return em.createQuery("SELECT c FROM Contact c").getResultList();
  | 	}
  | }

META-INF/persistance.xml :
<?xml version="1.0" encoding="UTF-8"?>
  | <persistence>
  |    <persistence-unit name="testdb">
  |       <jta-data-source>java:/DefaultDS</jta-data-source>
  |       <properties>
  |          <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
  |          <property name="hibernate.show_sql" value="true"/>
  |          <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
  |       </properties>
  |    </persistence-unit>
  | </persistence>

This EJB is not correctly loaded in JBoss :

  |     jboss.j2ee:ear=test-jboss-ear.ear,jar=test-jboss-ejb.jar,name=ContactServiceBean,service=EJB3
  | 

Moreover, my web module cannot call the EJB because the following exception is throwed : javax.naming.NameNotFoundException: ContactServiceBean not bound.

Anybody can explain me the trouble please ?
Thanks,
