Here is the relevant code used:

import org.jboss.logging.Logger;

public class MBeanLocator
{
private static final Logger log = Logger.getLogger(PeerLocator.class);

public static FooMBean locateMBean(String ipAddress)
{
Hashtable<String, String> props = new Hashtable<String, String>();
MBeanServerConnection wrapper = null;
Properties props = new Properties();
InitialContext ctx = null;

try
{
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.NamingContextFactory");
props.put(Context.PROVIDER_URL, "jnp://" + ipAddress + ":" + 1099 + "/");

props.put("jnp.timeout", "10000");
props.put("jnp.sotimeout", "3000");
props.put("jnp.maxRetries", "5");


ctx = new InitialContext(props);

MBeanServerConnection server = (MBeanServerConnection) ctx.lookup(jmx/invoker/RMIAdaptor);
Object proxy = Proxy.newProxyInstance(MBeanServerProxy.class.getClassLoader(),
MBeanServerProxy.INTERFACES,
new MBeanServerProxy(server));
wrapper = (MBeanServerConnection) proxy;
