*Result*: JMX Redux.

*This article provides information on web-service access and Java virtual machine management in Java 5.0. Java Management Extensions (JMX) is the management standard both in J2EE and J2SE. Because JMX greatly simplifies the instrumentation of resources and remote access to them, it is becoming the de facto standard for Java application and services management. Java 5.0 includes the JMX 1.2 specification together with the remote application program interfaces as well as virtually machine-level instrumentation that enables off-the-shelf virtual machine (VM) monitoring and management. Moreover, JMX management capabilities can be leveraged by using a number of open-source tools that provide management consoles and communications infrastructure. You can add JMX in Java 5.0 VMs with different communication connectors and adapters to provide a multiprotocol view of applications and harness the benefit from the existing consoles to monitor and control your applications, services and resources in production environments. The article also discusses Paul Tremblett's Java Management Extensions (JMX), which focused on how to set up a management agent and use an HTTP adapter to remotely interact with it. It shows how you can access MBeans from your own code. Additionally, the authors provide an in-depth view of Java's management technology and describe the monitoring and management information included in Java 5.0. The authors also create a web services text-based management console and present MC4J, an open-source, visual management console for JMX that uses Remote Method Invocation.*
