Appeler une méthode sur un EJB

Version imprimable

Bonjour,

J'ai effectué un bean entité MembreBean qui possede une méthode findByprimaryKey

Quand j'essaie de tester j'appelle d'abord l'ejb de la facon suivante:
Code:

1 2 3 4 5 6 public com.access.interfaces.MembreBeanHome getMembreBeanHome() throws javax.naming.NamingException { Context ctx = new InitialContext(); return (MembreBeanHome) ctx.lookup("java:comp/env/ejb/MembreBean"); }
En effet dans l'interface MembreBeanHome j'ai

Citation:

public static final String COMP_NAME="java:comp/env/ejb/MembreBean";
public static final String JNDI_NAME="ejb/MembreBean";

Pourtant lors du lookup j'ai l'erreur "ejb not bound "
Quelqu'un peut -il m'aider a trouver la solution?

Merci bcp!!

Regarde dans la console jmx si il est bien référencé à cette adresse dans le jndi.

le jndi-name ca devrait pas plutot être :
Code:

et le lookup
Code:

1 2 ctx.lookup("/ejb/MembreBean");
enfin le nom on s'en fout mais le même.

Bonjour,

J'ai rajouté la ligne"jndi name "suivante dans jboss.xml :

Citation:

<entity>
<ejb-name>MembreBean</ejb-name>
<jndi-name>ejb/MembreBean</jndi-name>
<local-jndi-name>MembreBeanLocal</local-jndi-name>

Mais j'ai toujours la meme erreur ...
27/01/2006, 10h20
zekey

et tu as changé la partie lookup ?
27/01/2006, 10h44
c+cool
oui par contre j'ai testé cette méthode qui fonctionne :
Code:

1 2 return (MembreBeanHome) ctx.lookup(MembreBeanHome.JNDI_NAME);
Mais ensuite j'ai une autre erreur ...

et le lookup

Code:

1 2 ctx.lookup("/ejb/MembreBean");

enfin le nom on s'en fout mais le même.
Arf j'ai fait une erreur, désolé le / est en trop dans le lookup. C'est pour ca que ca marche avec ce que tu viens de faire.
Donc je résume le premier problème est que ta def dans jboss.xml et ton lookup n'étais pas bon.

Maintenant le deuxieme problème ?

Mon autre problème est le suivant:
Lorsque j'appelle la méthode find suivante j'obitens le message d'erreur qui suit
Code:

1 2 3 4 5 6 7 public MembreBeanHome find(String pk) { MembreBeanHome membreBeanHome=null;; try { membreBeanHome = getMembreBeanHome();//.findByPrimaryKey(pk); MembreBean membreBean =(MembreBean)membreBeanHome.findByPrimaryKey("lo");
