JMXWrapper is a wrapper class that allows the creation of dynamic JMX MBeans by simply annotating a normal Java class. Names and descriptions of JMX beans, attributes, operations and operation parameters can also be localized using standard Java ResourceBundles.


 @JMXBean(description = "My first JMX bean test")
 public class MyBean {
 	int level = 0;
 	@JMXBeanAttribute(name = "Floor Level", description = "The current floor level")
 	public int getLevel() {
 		return level;
 	public void setLevel(int newLevel) {
 		level = newLevel;
 	@JMXBeanOperation(name = "Echo Test", description = "Echoes the parameter back to you")
 	public String myMethod(
 			@JMXBeanParameter(name = "Input", description = "String of what to echo") String param) {
 		return "You said " + param;

Now you can use the JMXWrapper to publish a bean including the annotated informations to the JMX Server:

MyBean bean = new MyBean();
JMXBeanWrapper wrappedBean = new JMXBeanWrapper(bean);
MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
mbs.registerMBean(wrappedBean, new ObjectName(",name=My Bean"));

That's all!

Sorting the attributes and operations

To sort attributes and operations in a certain way, you have to mark the bean as sorted. By default, attributes and operations will be sorted by their name. You can specify a sortValue for the operations and attributes to override the default value.

      public class MyBean {
          int level = 0;
          @JMXBeanAttribute(nameKey="level", descriptionKey="levelDescription", sortKey="1")
          public int getLevel() {
              return level;
          public String methodX(String p1) {
              return p1;

Using ResourceBundles for names and descriptions

Instead of specifying names and descriptions directly into the annotations, you can use standard Java ResourceBundles. You just have to specify the bundle name in the JMXBean annotation and then annotate the bundle keys for beans, attributes, operations and parameters:

        public class MyBean {
           int level = 0;
           @JMXBeanAttribute(nameKey="level", descriptionKey="levelDescription")
           public int getLevel() {
               return level;

Annotation types

Four annotation types can be used:

JMXBean          : Marks and describes a class to be used as a dynamic JMX bean. 
JMXBeanAttribute : Marks and describes methods (setter/getter) in a JMXBean to be
                   used as a JMX attribute. 
JMXBeanOperation : Marks and describes a method to be used as a JMX operation. 
JMXBeanParameter : Describes a method parameter for JMX operation parameters 

Project layout
