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 :

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,
Regards,
