Hi,
I'm trying to call EJB from JSP.
My EJB :
*+package ejb;+*
*+import javax.ejb.Stateless;+*
*+import org.jboss.ejb3.annotation.Clustered;+*
*+@Stateless+*
*+@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

*+ <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
