I am having trouble looking up the jmx/rmi/RMIAdaptor within JBoss 4.2.0 GA GA. I looked all over site and did not find an answer. This did work with JBoss 4.0.3SP1 and the same configuration which makes me scratch my head. I have the following policy file and -Djava.security.policy variable pointing to this file in my run.bat script. grant { | permission java.security.AllPermission; | permission java.util.PropertyPermission "*", "read,write"; | permission java.net.SocketPermission "*", "connect,accept,resolve,listen"; | }; This following simple example from the Wiki fails with the exception to follow: public static void main( String args[] ) | throws Exception | { | MBeanServerConnection server; | Properties prop = new Properties(); | prop.put( Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); | String serverHost = InetAddress.getLocalHost().getHostName(); | prop.put(Context.PROVIDER_URL, serverHost); | InitialContext initialContext = new InitialContext( prop ); | | server = ( MBeanServerConnection ) initialContext.lookup( "jmx/rmi/RMIAdaptor" ); | ObjectName on = new ObjectName( "jboss.system:type=Server" ); | Object ver = server.getAttribute( on, "Version" ); | System.out.println( "Version " + ver ); | } | Here is the exception of Connection Refused...

However I can telnet to 1099 on my local machine and get a connection, so that is why I am confused about the Connection refused exception. At first I thought it was a security problem but it's not even getting that far. Any help would be most appriciated.
