My sever is up and listening at http://127.0.0.1:8080.
Below is the code of client application

package com.hello.client;

import javax.naming.InitialContext;
import javax.naming.NamingException;

import com.hello.bean.IMessageHandler;

/**
 * @author arafique
 *
 */
public class HelloWorld {
	public static void main(String[] args) {
		try {
			InitialContext initialContext = new InitialContext();
			IMessageHandler msgHandler = 
				(IMessageHandler) initialContext.lookup("HelloWorld/MessageHandlerBean/remote");
			if (msgHandler == null) {
				System.out.println("nullllll");
			} else {
				System.out.println("not nullllll");
				msgHandler.saveMessages();
				msgHandler.showMessages();
			}
		} catch (NamingException e) {
			e.printStackTrace();
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

}

Here are my jndi.properties

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=127.0.0.1:8080

Please help me out

Thanks

[Jaikiran Pai]

The naming port is by default 1099. The port you are using 8080 is the HTTP port. So your jndi.properties should be changed to :

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory  
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces  
java.naming.provider.url=127.0.0.1:1099

[Amirr Rafique]

Jaikiran

I have changed the port as you said but problem remains same.

[Jaikiran Pai]

What does the following command output from the system where you are running the client:

telnet 127.0.0.1 1099

And what command did you use to start the server?

By the way, i just noticed that the exception stacktrace shows this:

at com.sun.enterprise.iiop.IIOPSSLSocketFactory.createSocket(IIOPSSLSocketFactory.java:332)

which doesn't look right to me. Are you sure your jndi.properties is being picked up in the classpath? You can try deleting that file and if you still see this exact same error then your jndi.properties is not being picked up.

Please try this to get the initial context

public static Context getInitialContext()throws javax.naming.NamingException{
	Properties p = new Properties();
	p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.NamingContextFactory");//will work with UserTransaction factory
	p.put(Context.URL_PKG_PREFIXES, " org.jboss.naming:org.jnp.interfaces");
	p.put(Context.PROVIDER_URL, "localhost:1099");//local

	try {
		return new javax.naming.InitialContext(p);
	} catch (NamingException e) {
		System.out.println("Exception in StatelessClient.getInitialContext is:"+e.getMessage());
		e.printStackTrace();
		return null;
	}
}    

Please note in this sample the context factory is different
org.jboss.naming.NamingContextFactory

[Amirr Rafique]

 public static Context getInitialContext()throws javax.naming.NamingException{   
    Properties p = new Properties();   
    p.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.NamingContextFactory");//will work with UserTransaction factory   
    p.put(Context.URL_PKG_PREFIXES, " org.jboss.naming:org.jnp.interfaces");   
    p.put(Context.PROVIDER_URL, "localhost:1099");//local   
  
    try {   
        return new javax.naming.InitialContext(p);   
    } catch (NamingException e) {   
        System.out.println("Exception in StatelessClient.getInitialContext is:"+e.getMessage());   
        e.printStackTrace();   
        return null;   
    }   
}     

after using above code snippet I get following exception

  Exception in StatelessClient.getInitialContext is:Cannot instantiate class: org.jboss.naming.NamingContextFactory

You are right jaikiran, deleting properties file doesnot change error. Where should i palce properties file to make it picked by classpath.

[Vikram Saxena]

The jndi.properties should be present in the $JBOSS_HOME/<<server>>/conf directory. See if it helps.

[Anurag Blore]

Root exception is java.lang.ClassNotFoundException: org.jboss.naming.NamingContextFactory]

to resolve above include this jar from jboss in your class path
jbossall-client.jar it should be in your jboss/client folder.

I would recommend to add all the jars from jboss/client folder.

what is the jboss version?

[Amirr Rafique]

Mates thanks for all your help and support. Finally I have run "Hello World"
