How do I enable remote JMX access to a JVM using JConsole?

Activating JMX on JVM for Access via JConsole

To enable remote JMX access to a Java Virtual Machine (JVM), you need to activate JMX and set appropriate command-line arguments. Here's how you can do it:

Refer to the official documentation at http://java.sun.com/javase/6/docs/technotes/guides/management/agent.html for full details.

Command-Line Arguments:

Start your JVM with the 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 example:

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

Note:

• The -Dcom.sun.management.jmxremote.local.only=false argument is not strictly necessary but is recommended for Ubuntu compatibility.
• Exercise caution with -Dcom.sun.management.jmxremote.authenticate=false, as it makes access available to anyone. If you're using JMX only on your local machine, this setting may not be an issue.

Additional Tip:

If you encounter connection issues, try setting the following parameter as well:

-Djava.rmi.server.hostname=127.0.0.1
