public class Main {


public static void main(String[] args) {

try{

Context con = new InitialContext();
Object objRef = con.lookup("ejb/CartBean");
CartRemoteHome home = (CartRemoteHome)PortableRemoteObject.narrow(objRef,CartRemoteHome.class);

CartRemote cartremote = home.create();

cartremote.setInfo("Hello call a ejb method ") ;
System.out.println("The Message From Bean " + cartremote.getInfo());




}catch(Exception ex){
System.out.println("The Error : " + ex);

instead of Object objRef = con.lookup("ejb/CartBean");

try: Object objRef = con.lookup("env/comp/ejb/CartBean");

not sure but worth trying....

You might have to set some properties in jndi.properites
Like:
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.provider.url=localhost:1099

And please change your name according to the policy :

Thanks.

hi,


i got a soluction of my problem , so soluction is :


package com;

import com.sun.rsasign.c;
import javax.naming.InitialContext;

/**
*
* @author Shivam1
*/
public class testbean {

/** Creates a new instance of testbean */
public testbean() {

try{

com.exampleRemote updateAvailableBudgetRemote = lookupexampleBean() ;

System.out.println(updateAvailableBudgetRemote.getInfo());

}catch(Exception ex){
System.out.println(ex);
}
}

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
testbean t1 = new testbean();
}

private com.exampleRemote lookupexampleBean() {
try {

InitialContext ctx = new InitialContext();
ctx.addToEnvironment("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
ctx.addToEnvironment("java.naming.factory.url.pkgs", "org.jboss.naming rg.jnp.interfaces");
ctx.addToEnvironment("java.naming.provider.url","localhost");

Object remote = ctx.lookup("test/Tester");
com.exampleRemoteHome rv = (com.exampleRemoteHome) javax.rmi.PortableRemoteObject.narrow(remote, com.exampleRemoteHome.class);
return rv.create();
}
catch(javax.naming.NamingException ne) {
java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE,"exception caught" ,ne);
throw new RuntimeException(ne);
}
catch(javax.ejb.CreateException ce) {
java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE,"exception caught" ,ce);
throw new RuntimeException(ce);
}
catch(java.rmi.RemoteException re) {
java.util.logging.Logger.getLogger(getClass().getName()).log(java.util.logging.Level.SEVERE,"exception caught" ,re);
throw new RuntimeException(re);
