Interface Summary Interface Description ClassLoaderRepository Instances of this interface are used to keep the list of ClassLoaders registered in an MBean Server.MLetMBean Exposes the remote management interface of the MLet MBean.PrivateClassLoader Marker interface indicating that a ClassLoader should not be added to theClassLoaderRepository. -
Class Summary Class Description DefaultLoaderRepository Deprecated UseMBeanServer.getClassLoaderRepository()} instead.MLet Allows you to instantiate and register one or several MBeans in the MBean server coming from a remote URL.MLetContent This class represents the contents of theMLETtag.PrivateMLet An MLet that is not added to theClassLoaderRepository.
Package javax.management.loading Description
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.
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 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.
