Bonjour
je suis entraine de developper un site web en utilisant: ejb+eclipse+glassfish.
j'ai crée 3 projets: un projet EJB+un projet EJBClient+un projet EAR.
dans le projet EJB j'ai met les éléments suivants:entity+un web service stateless +persistence.xml.
lorsque j'essaie de deployer mon projet j'obtient l'erreur suivant:

[exec] CLI171 Command deploy failed : Deploying application in domain failed; Could not resolve a persistence unit corresponding to the persistence-context-ref-name [org.brams.stage.ideajam.ws.Idees/em] in the scope of the module called [ideajamEAR#E:\glassfish\domains\domain1\applications\j2ee-apps\ideajamEAR\ideajamEJB_jar]. Please verify your application.

entity:

import java.util.HashSet;
import java.util.Set;

import javax.ejb.Stateless;
import javax.persistence.Column;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@SuppressWarnings({ "unused", "serial" })
@Entity
@Table(name="user")
public class User {

@Id
@Column(name = "ID", nullable = false)
@GeneratedValue(strategy = GenerationType.AUTO)
private long id;

@Column(name = "FIRSTNAME", length = 50, nullable = false)
private String firstName;

public User(){

}
public long getId() {
return id;
}
public void setId(long id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
}

Web service statless:

import java.util.List;

import javax.ejb.Stateless;
import javax.jws.WebMethod;
import javax.jws.WebService;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.brams.stage.ideajam.entities.Idee;
import org.brams.stage.ideajam.entities.User;


@Stateless(name = "Users")
@WebService(serviceName = "UserService")
public class Users {

@PersistenceContext
private EntityManager em;

@WebMethod
public User saveUser(User user) {
em.persist(user);
return user;
}

@WebMethod
public User updateUser(User user) {
return em.merge(user);
}

@WebMethod
public void deleteUser(Long userId) {
User user = em.find(User.class, userId);
em.remove(user);

persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence">

Merci

je suis pas sur mais tente ça dans web service stateless :


@PersistenceContext(unitName="jpa")
private EntityManager em;

[dalhia]

le problème est résolu. j'ai remplacé, dans le fichier persistence.xml, transaction-type="RESOURCE_LOCAL" par transaction-type="JTA"
merci pit9.76
