Error EJB project - java.lang.reflect.UndeclaredThrowableException
Hi everyone,
I am getting an exception when I try to call a method from EJB. In my class called ClientEJB I call the method " getAllCategories() " from session EJB implementation
- In my EJB Project:
This is my entity bean called "Categorie"
@Entity
@Table(name="CATEGORIE")
public class Categorie implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="ID_CATEGORIE")
private Long idCategorie;
private String libelle;
private String description;
@OneToMany(mappedBy="categorie")
List<Article> listeArticles;
....
/*with getters and setters*/
....
}
NB: There is an Entity called "Article" who has a bi-directional relation with "Categorie"
- "Article" has Many-To-One relation with "Categorie"
- and "Categorie" has One-To-Many relation with "Article"
Below is my "Article" Class :
@Entity
@Table(name="ARTICLE")
public class Article implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name="ID_ARTICLE")
private Long idArticle;
private String libelle;
private double prix;
@Column(name="NOMBRE_STOCK")
private int nombreStock;
private String description;
private byte[] image;
@ManyToOne
@JoinColumn(name="ID_CATEGORIE")
private Categorie categorie;
....
/*with getters and setters*/
....
}
and this is the session bean implementation class: called "CategorieEJBImpl" who implements a two Interfaces (Local and Remote)
@Stateless(name="CATE")
public class CategorieEJBImpl implements ICategorieLocal,ICategorieRemote {
@PersistenceContext(unitName="UP_FOURNITURE")
private EntityManager em;
@Override
public void addCategorie(Categorie c) {
em.persist(c);
}
@Override
public List<Categorie> getAllCategories() {
Query req = em.createQuery("select c from Categorie c");
return req.getResultList();
}
....
}
- In my java project called "ClientEJB":
public class ClientEJB {
public static void main(String[] args) {
try{
Properties pr = new Properties();
pr.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
Context ctx = new InitialContext(pr);
ICategorieRemote stub = (ICategorieRemote) ctx.lookup("ejb:/FournitureScoEJB/CATE!metier.session.ICategorieRemote");
List<Categorie> lstC = stub.getAllCategories();
System.out.println("Liste Categories:");
for(Categorie c:lstC){
System.out.println(c.getIdCategorie()+" -- "+c.getLibelle()+" -- "+c.getDescription());
}
}
This is the error:
