Hi,

I'm trying to call EJB from JSP.

My EJB :

*+package ejb;+*
*+import javax.ejb.Stateless;+*
*+import org.jboss.ejb3.annotation.Clustered;+*
*+ at Stateless+*
*+ at Clustered+*
*+public class CompteurEJB implements CompteurEJBRemote {+*

*+    @Override+*
*+    public void affiche(int msg) {+*
*+        System.out.println(msg);+*

*+    }+*

*+}+*

*+
+*
My remote EJB :
+*package ejb;*+
+*import javax.ejb.Remote;*+

+*@Remote*+
+*public interface CompteurEJBRemote {*+
+*    public void affiche(int msg);*+
+*}*+

And this package ejb is in ejbSLSBCluster.jar.

My client (JSP) :

+*<?xml version="1.0" encoding="UTF-8" ?>*+
+*<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>*+
+*<%@ page import= "ejb.CompteurEJBRemote"%>*+
+*<%@ page import= "javax.naming.*"%>*+
+*<%@ page import= "java.text.*"%>*+
+*<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">*+
+*<html xmlns=" http://www.w3.org/1999/xhtml http://www.w3.org/1999/xhtml">*+
+*<head>*+
+*<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />*+
+*<title>JSP de stress</title>*+
+*</head>*+
+*<body>*+
+*    <table>*+
+*        <%!*+
+*            public void jspInit () {*+
+*                try {*+
++ +*                    InitialContext ctx = new InitialContext();*+
+*                    CompteurEJBRemote s = (CompteurEJBRemote) ctx.lookup("CompteurEJB/remote");*+
+*                    for (int i = 0; i < 300; i++) {*+
+*                        %><tr><td>test<%!*+
+*                        s.affiche(i);*+
++ +*                        %></td></tr><%!*+
+*                     }*+
+*                }*+ 
+*                catch (Exception e)  { e.printStackTrace (); }*+
+*            }*+
+*        %>*+
+*    </table>*+
+*</body>*+
+*</html>*+

My JSP is in .war where i have :

ejbSLSBCluster.jar in WEB-INF/lib

jndi.properties in WEB-INF :
+*java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory*+
+*java.naming.provider.url=jnp://127.0.0.1:1099*+
+*java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces*+

My web.xml :

*+<?xml version="1.0" encoding="UTF-8"?>+*
*+<web-app xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance http://www.w3.org/2001/XMLSchema-instance"+*
*+    xmlns=" http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee" xmlns:web=" http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"+*
*+    xsi:schemaLocation=" http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee  http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"+*
*+    id="WebApp_ID" version="2.5">+*
*+    <display-name>clientcompteurweb</display-name>+*

*+    <servlet>+*
*+        <description>Point d'entree de l'application</description>+*
*+        <display-name>Controlpea</display-name>+*
*+        <servlet-name>Controlpea</servlet-name>+*
*+        <servlet-class>com.saintquentin.pea.Controlpea</servlet-class>+*
*+    </servlet>+*
*+    <servlet-mapping>+*
*+        <servlet-name>Controlpea</servlet-name>+*
*+        <url-pattern>/Controlpea</url-pattern>+*
*+    </servlet-mapping>+*

*+    <resource-env-ref>+*
*+        <description>Bind de mon bean</description>+*
*+        <resource-env-ref-name>CompteurEJB/remote</resource-env-ref-name>+*
*+        <resource-env-ref-type>ejb.CompteurEJB</resource-env-ref-type>+*
*+        <mapped-name>java:CompteurEJB/remote</mapped-name>+*
*+    </resource-env-ref>+*

*+</web-app>+*

But when i execute my jsp i have this error :
17:06:27,649 ERROR [STDERR] javax.naming.NameNotFoundException: CompteurEJB not bound

I think that i forgot something but what??

I use JBOSS 5.1 and Eclipse 3.4

Thanks for your help
