Working with HTTP adaptor going fine,
Tring to invoke example with jconsole.exe produces exception (the situation happens unsing jre 1.4 and 1.5):
the code:
public class Server {
    public static void main(String[] args) {
        try {
            // Instantiate the MBean server
            System.out.println("\nCreate the MBean server");
            MBeanServer mbs = MBeanServerFactory.createMBeanServer();
            // Create a JMXMP connector server
            System.out.println("\nCreate a JMXMP connector server");
            JMXServiceURL url = new JMXServiceURL("jmxmp", null, 5551);
            JMXConnectorServer cs =
                JMXConnectorServerFactory.newJMXConnectorServer(url, null, mbs);
            // Start the JMXMP connector server
            System.out.println("\nStart the JMXMP connector server");
            cs.start();
            System.out.println("\nJMXMP connector server successfully started");
            System.out.println("\nWaiting for incoming connections...");
        } catch (Exception e) {
            e.printStackTrace();
}consol:
Create the MBean server

Hi,
We belive that you used the default connector RMIConnector in your jconsole to connect your JMXMP connector server.
What you should do is to:
1) start your jconsole with the jmxmp classes:
jconsole -J-Djava.class.path=JAVA_HOME/lib/jconsole.jar:JAVA_HOME/lib/tools.jar:jmxremote_optional.jar
(see http://java.sun.com/javase/6/docs/technotes/guides/management/jconsole.html)
2) specify your server url address in the jconsole connecting window:
service:jmx:jmxmp://boat:5551
you should substitue "boat" to your host name
3)connect
Hope this helps and let's know if you still have problem.
