    The relevant documentation can be found here:

    http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html

    Start your program with following parameters:

    -Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.rmi.port=9010
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false

    For instance like this:

    java -Dcom.sun.management.jmxremote \
  -Dcom.sun.management.jmxremote.port=9010 \
  -Dcom.sun.management.jmxremote.local.only=false \
  -Dcom.sun.management.jmxremote.authenticate=false \
  -Dcom.sun.management.jmxremote.ssl=false \
  -jar Notepad.jar

    -Dcom.sun.management.jmxremote.local.only=false is not necessarily required
    but without it, it doesn’t work on Ubuntu. The error would be something like
    this:

    01 Oct 2008 2:16:22 PM sun.rmi.transport. customer .TCPTransport$AcceptLoop executeAcceptLoop
WARNING: RMI TCP Accept-0: accept loop for ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=37278] throws
java.io.IOException: The server sockets created using the LocalRMIServerSocketFactory only accept connections from clients running on the host where the RMI remote objects have been exported.
    at sun.management.jmxremote.LocalRMIServerSocketFactory$1.accept(LocalRMIServerSocketFactory.java:89)
    at sun.rmi.transport. customer .TCPTransport$AcceptLoop.executeAcceptLoop(TCPTransport.java:387)
    at sun.rmi.transport. customer .TCPTransport$AcceptLoop.run(TCPTransport.java:359)
    at java.lang.Thread.run(Thread.java:636)

    see https://bugs.java.com/bugdatabase/view_bug?bug_id=6754672

    Also be careful with -Dcom.sun.management.jmxremote.authenticate=false which
    makes access available for anyone, but if you only use it to track the JVM on
    your local machine it doesn’t matter.

    Update:

    In some cases I was not able to reach the server. This was then fixed if I set this parameter as well: -Djava.rmi.server.hostname=127.0.0.1
