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 java.lang.ClassLoader can be used as a class loader to create other MBeans via the method javax.management.MBeanServer#createMBean(String, ObjectName, ObjectName, Object[], String[]) , and to instantiate arbitrary objects via the method javax.management.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.
Additionally, an MLet can read a configuration
file that specifies a set of MBeans to be registered in the same
MBean Server as the MLet.
Every MBean Server has a class loader repository
containing all MBeans registered in that MBean Server that
are of a subclass of java.lang.ClassLoader . The class
loader repository is used by the forms of the
createMBean and 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.
If an MBean implements the interface PrivateClassLoader ,
then it is not added to the class loader repository. The class
PrivateMLet is a
subclass of MLet that implements
PrivateClassLoader.
