[EJB] Accès JNDI à un EJB

Accès JNDI à un EJB

salut,

voici le problème : je n'arrive pas à appeler via JNDI un EJB.

j'ai créé un projet EAR qui contient un projet EJB, un projet EJBClient et un projet JPA, tous les 3 peuplés avec des EJB, une classe avec "main", et des entities.

voici le code d'un EJB:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 package ejb.customer; import(...) @Stateless public class CustomerBean implements CustomerLocal, CustomerRemote { @PersistenceContext(unitName="petstorePU") private EntityManager em; public Customer authenticate(String login, String password) { if (login==null || login.equals("")) throw new ValidationException("Invalid login"); (...)
voici le code de la classe cliente:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 package source_client; import javax.naming.Context; import javax.naming.InitialContext; import source.customer.Customer; public class client1 { /** * @param args */ public static void main(String[] args) { try { Context ctx=new InitialContext(); ejb.customer.CustomerRemote rem=(ejb.customer.CustomerRemote) ctx.lookup("ejb.customer.CustomerBean/remote"); rem.createCustomer(new Customer(1L,"jambon","rose","jean","bonrause","0018654118","jeanroi@gmail.com",new java.util.Date(1978,02,10),19,null),new source.Address(1,"4 rue des roses","","METZ","Moselle","57000","FRANCE")); System.out.println ("--- Hello, clients ---"); for (source.customer.Customer client : rem.findCustomers()) { System.out.println ("client : "+client); } } catch (Exception e) { e.printStackTrace(); } } }
et voici le code de jndi.properties, que j'ai placé dans le répertoire des sources du client:
Code:

1 2 3 4 java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces java.naming.provider.url=localhost:1099
j'ai aussi ajouté un fichier persistence.xml dans le répertoire META-INF du projet EJB:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 <persistence> <persistence-unit name="petstore_ejb"> <jta-data-source>java:/MySqlDS</jta-data-source> <properties> <property name="hibernate.hbm2ddl.auto" value="update"/> <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/> <property name="hibernate.show_sql" value="true"/> <property name="hibernate.connection.password" value="petstorepwd"/> <property name="hibernate.connection.username" value="petstorelg"/> </properties> </persistence-unit> </persistence>
voici la liste des références JNDI de JBOSS, je n'y ai pas trouvé ce qui pourrait être l'EJB:

j'oubliais : voici le message d'erreur : "javax.naming.NameNotFoundException: CustomerBean not bound"

j'ai maintenant les EJB qui sont déployés via JNDI : voici un extrait de la page JNDIView sur la page web de JBOSS :

mais je n'arrive toujours pas à m'y connecter avec le classe client : regardez la photo, on y voit que l'EJB est déployé et l'appel refusé.

Salut olivier57b, aurais-tu résolu ton problème...? :oops:

Ca m'intéresse ! ;)

Je suis la même voie que toi, à savoir que je me mets à JEE en suivant le livre d'A. Goncalves.

J'en suis encore à essayer de comprendre comment reprendre l'arborescence de l'application dans un Enterprise Application Project sous Eclipse... :?
