Hi expert,

I create JAR file for class in eclipse like:

Package Haitham

import java.io.IOException;

import java.net.URISyntaxException;

import java.rmi.RemoteException;

import java.util.Properties;

import java.util.logging.Logger;

import javax.jms.Connection;

import javax.jms.ConnectionFactory;

import javax.jms.JMSException;

import javax.jms.MessageProducer;

import javax.jms.Session;

import javax.jms.TextMessage;

import javax.naming.Context;

import javax.naming.InitialContext;

import javax.naming.NamingException;

public class TracingMessages

{

          public static void main(String[] args)

          {

          }

          public static String SendMessages(String Queuename,String msg) throws IOException, URISyntaxException

{

                    String body="";

                            try

                            {

                                          Context init =TracingMessages.getInitialContext();

                                      javax.jms.Queue destination =        (javax.jms.Queue) init.lookup("/queue/" +Queuename);

                                           ConnectionFactory connectionFactory =   (ConnectionFactory) init.lookup("ConnectionFactory");

                                  Connection connection = connectionFactory.createConnection();//

                                  Session session = connection.createSession(false, Session.AUTO_ACKNOWLEDGE);

                                  MessageProducer producer = session.createProducer(destination);

                                  TextMessage message = session.createTextMessage();

                                  message.setText(msg );

                                  connection.start();

                                  System.out.println("connect strat");

                                  producer.send(message);

                                  body = message.getText();

                                  session.close();

                                  connection.close();

                              }

                            catch (Exception e)

                              {

                                  return(e.toString());

                              }

                        return body    ;

                    }

public static Context getInitialContext () throws JMSException,NamingException,RemoteException

          {

                    Properties prop = new Properties();

              prop.setProperty("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");

                    prop.setProperty("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");

                    prop.setProperty("java.naming.provider.url", "jnp://127.0.0.1:1099");

                    Context context = new InitialContext(prop);

                    return context;}

Then i converts JAR file to DLL after that i used in VISUAL STUDIO 2012 to send message to Jboss 4.2.3 ,it is worning Well if i used inside WINDOWS APPLICATION

but

if i used the same DLL class inside web application i got the follwoing error:

** javax.naming.NoInitialContextException: Cannot instantiate class: org.jnp.interfaces.NamingContextFactory [Root exception is java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory**

why??????

any one have idea?

Thanks in advanced
