Hi,

I have created simple ejb3 and deployed on jboss 7.1 server.

When I am trying to lookup using the client code, I am getting the below exception.

public class ClientUtility {  
/*location of JBoss JNDI Service provider the client will use.    It should be URL string.*/ 
private static final String PROVIDER_URL = "remote://localhost:4447";  
/*specifying the list of package prefixes to use when    loading in URL context factories. colon separated*/ 
private static final String JNP_INTERFACES = "org.jboss.naming:org.jnp.interfaces"; 
/*Factory that creates initial context objects.    fully qualified class name. */
private static final String INITIAL_CONTEXT_FACTORY = "org.jnp.interfaces.NamingContextFactory";
private static Context initialContext;    

public static Context getInitialContext() throws NamingException    {  
  if (initialContext == null) {         
   //Properties extends HashTable          
   Properties prop = new Properties();      
   prop.put(Context.INITIAL_CONTEXT_FACTORY, INITIAL_CONTEXT_FACTORY);    
   prop.put(Context.URL_PKG_PREFIXES, JNP_INTERFACES);        
   prop.put(Context.PROVIDER_URL, PROVIDER_URL); 
   //prop.put(Context.PROVIDER_URL, "remote://localhost:4447");
   prop.put(Context.SECURITY_PRINCIPAL, "admin");
   prop.put(Context.SECURITY_CREDENTIALS, "fifa@1234");

   initialContext = new InitialContext(prop);     
   }      
  return initialContext;   
  }
}
