Provides the classes which implement advanced dynamic loading. See the chapter Advanced Dynamic Loading in the JMX Specification .
An MBean that is of a subclass of
ClassLoader can be used as a class loader to create other MBeans via the method
MBeanServer.createMBean(String, ObjectName, ObjectName, Object, String) , and to instantiate arbitrary objects via the method
MBeanServer.instantiate(String, ObjectName, Object, String) . The
MLet class is an example of such an MBean. It is a
URLClassLoader, so the list of URLs to load classes from can be configured.
MLet can read a configuration file that specifies a set of MBeans to be registered in the same MBean Server as the
Every MBean Server has a class loader repository containing all MBeans registered in that MBean Server that are of a subclass of
ClassLoader. The class loader repository is used by the forms of the
instantiate methods in the
MBeanServer interface that do not have an explicit loader parameter. It is also used by the
MLet class when it does not find a class in its own set of URLs.
