If the JMX monitoring feature in a Java application is not working, you can try the following solutions:

Check if the JMX port is configured correctly: Make sure that the JMX port is properly configured when the Java application starts, and that no other process is using that port.
Check JMX authentication and authorization configuration: Make sure that if JMX authentication and authorization are enabled, the configuration is correct, and that the username and password are properly set.
Check the firewall and network settings: Ensure that the JMX port is open in the firewall, and that the network configuration allows remote access to the JMX port.
Check the Java application logs: Review the log files of the Java application to see if there are any error messages related to JMX.
Diagnose with JConsole tool: Connect to the Java application using JConsole tool and check if it successfully connects and retrieves monitoring data.
Check the registration status of JMX MBeans: Verify that the JMX MBeans registered in the Java application are correct and ensure that the objects that need to be monitored are registered properly.

The issue of JMX monitoring not working in Java applications can be identified and fixed using the methods mentioned above.
