In the Java 2, Platform Standard Edition 5.0, the Java Monitoring and Management Console (JConsole) was introduced. JConsole is used to monitor the Sun Java System Application Server. You can use either the JConsole remote tab, or the advanced tab to connect to the Application Server.
Remote Tab: identify the username, password, administration server host, and JMS port number (8686 by default), and select Connect.
Advanced Tab: identify the JMXServiceURL as service:jmx:rmi:///jndi/rmi://host:jms-port/jmxrmi and select Connect. The JMXServerURL is printed in the server.log file as well as output in the command window of the domain creation command.
