javax.naming.CommunicationException

[Suhas Mohamedali]

Hi,

I am calling an interface from my client ( simple java) from eclipse.

My client.java

 

package ejb.client;

import java.util.Properties;

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

import ejb.interfaces.AreaRemoteBI;


public class Client {
	
	
	public static void main(String[] a)  {
		
		
		Object ref = null;		

		        
		        Context ctx;
				try {
					ctx = getInitialContext();
					ref = ctx.lookup("AreaBean/remote");
				} catch (NamingException e) {
					
					e.printStackTrace();
				}      	
		        
		        AreaRemoteBI biCall = (AreaRemoteBI)ref;				
				String result =  null;					
				result = biCall.searchArea("IND");				
				System.out.println("\n The resul is:::"+result);


	}
	
	
    public static Context getInitialContext() 
            throws javax.naming.NamingException 
        {
    	Properties properties = new Properties();  
        properties.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.NamingContextFactory");  
        properties.put(Context.PROVIDER_URL, "jnp://localhost:1099");  
        properties.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");  
    	
    	return new InitialContext(properties);  
        }

}

I kept my remote interface in the same package of client ( client side). jndi.properties placed at the root folder of client...

I have both local and remote in the serverside. The local and remote interfaces, bean and entity have been bundled in a jar and deployed in JBOSS.

Now when I run my client as java program i am getting following exception
