[jboss-user] [JNDI/Naming/Network] - Problem when accessing JMX(RMIAdaptor) from JNDI namespace o

[GourabGuha]

Hi All,

I have problem to lookup RMIAdaptor from the JNDI namespace of Jboss.
The code that I have written is follows.

import java.util.Properties;
import javax.naming.InitialContext;

public class ServiceLocator 
{
	public static void main(String[] args) 
	{
		try
		{
			Properties enviornment = new Properties();
										  enviornment.setProperty("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
			enviornment.setProperty("java.naming.provider.url","jnp://localhost:1099");
			enviornment.setProperty("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
						
			InitialContext initialContext = new InitialContext(enviornment);
			initialContext.lookup("jmx/rmi/RMIAdaptor");
					
		}
		catch(Exception e)
		{
			e.printStackTrace();
			
		}
	}
}

When I am executing the program I am getting the following exception

javax.naming.NamingException: Could not dereference object [Root exception is javax.naming.CommunicationException [Root exception is java.io.InvalidClassException: org.jboss.invocation.InvokerInterceptor; unable to create instance]]
