Connection Refused looking up jmx/rmi/RMIAdaptor on JBoss_4_

[harleybl]

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...

I took out the jboss code and stepped through in the debugger and it is failing to connect to the socket, almost like it's not listening. 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.

Thanks,
Harley

I know it is too late, but nevertheless someone might find it useful.

My thought:

Did you start jboss with -b option

run -b ST-BLUMENXP


or instead of inet address hostname, you could put localhost.



I had a similar problem with Connection refused. I think JBoss doesn't allow all host/ip names by default.


It is only listens on 127/localhost by default and you have to provide -b option to bind on different ip/dns than the default.
