Document

Make a proxy for a Standard MBean in a local or remote MBean Server.

If you have an MBean Server mbs containing an MBean with ObjectName name , and if the MBean's management interface is described by the Java interface MyMBean , you can construct a proxy for the MBean like this:

 MyMBean proxy = JMX.newMBeanProxy(mbs, name, MyMBean.class);

Suppose, for example, MyMBean looks like this:

 public interface MyMBean { public String getSomeAttribute(); public void setSomeAttribute(String value); public void someOperation(String param1, int param2); }

Then you can execute:

proxy.getSomeAttribute() which will result in a call to mbs.
