How to Enable JMX on a JVM for Remote Access with jconsole?

Activating JMX on a JVM for jconsole Access

Accessing a JVM remotely with jconsole requires enabling Java Management Extensions (JMX) on the JVM. To do so, start the program with the following parameters appended to the command:

-Dcom.sun.management.jmxremote: Enables remote JMX access.
-Dcom.sun.management.jmxremote.port=9010: Specifies the port for remote JMX access (default: 9010).
-Dcom.sun.management.jmxremote.local.only=false: Allows connections from remote hosts (optional).
-Dcom.sun.management.jmxremote.authenticate=false: Disables authentication for remote access (not recommended for production environments).
-Dcom.sun.management.jmxremote.ssl=false: Disables SSL for remote access.

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

Additional Considerations:

• -Dcom.sun.management.jmxremote.local.only=false is not always required, but it may be necessary on Ubuntu.
• -Djava.rmi.server.hostname=127.0.0.1 may need to be set to resolve connection issues in certain scenarios.
• Disable authentication (-Dcom.sun.management.jmxremote.authenticate=false) with caution as it allows unrestricted access to the JVM.
