[jboss-user] [JNDI/Naming/Network] - JNDI Newbie - Please help !!!

[mrroger]

This is my code:

package test.main;
import org.jboss.jmx.adaptor.rmi.RMIAdaptor;
import java.util.*;
import javax.management.*;
import javax.naming.*;

public class TestMain {
	public static void main(String args[]) throws Exception {
		System.out.println("Starting");
		Properties props=new Properties();		props.put(InitialContext.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
		props.put(InitialContext.PROVIDER_URL, "jnp://localhost:1099");		   props.put(InitialContext.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");		
		InitialContext ic = new InitialContext(props);		
		Hashtable icHash = ic.getEnvironment();		
		Enumeration enumHash = icHash.keys();		
		System.out.println("Key num: " + icHash.size());		
		while(enumHash.hasMoreElements()) {
			Object nextIc = enumHash.nextElement();			
			System.out.print("Keys: "+nextIc.toString());
			System.out.println(" = "+icHash.get(nextIc));
		}		
		System.out.println("Initial Context ok: ");	
		NamingEnumeration names = ic.list("");	
		System.out.println("Has More: " + names.hasMoreElements());			
		while(names.hasMoreElements()) {
			System.out.println((String) names.nextElement().toString());
		}
		RMIAdaptor server = (RMIAdaptor) ic.lookup("jmx/invoker/RMIAdaptor");
		System.out.println("RMIAdaptor ok: "+server.getMBeanCount());
		System.out.println("Name: " + server.getDefaultDomain());
	
===>        ObjectName nameTest = new ObjectName("jboss:service=JNDIView");
		
		MBeanInfo info = server.getMBeanInfo(nameTest);
		System.out.println("Name: " + info.getClassName());		
		System.out.println("Finished");
	}
}

This is the error where arrow is:
