See the chapter <em>Advanced Dynamic Loading</em> in	the <a href="#spec">JMX Specification</a>.</p>       <p>An MBean that is of a subclass of {@link	java.lang.ClassLoader} can be used as a class loader to create	other MBeans via the method {@link	javax.management.MBeanServer#createMBean(String, ObjectName,	ObjectName, Object[], String[])}, and to instantiate arbitrary	objects via the method {@link	javax.management.MBeanServer#instantiate(String, ObjectName,	Object[], String[])}.  The {@link	javax.management.loading.MLet MLet} class is an example of	such an MBean.  It is a {@link java.net.URLClassLoader	URLClassLoader}, so the list of URLs to load classes from can	be configured.</p>       <p>Additionally, an <code>MLet</code> can read a configuration	file that specifies a set of MBeans to be registered in the same	MBean Server as the <code>MLet</code>.</p>       <p>Every MBean Server has a <em>class loader repository</em>	containing all MBeans registered in that MBean Server that	are of a subclass of {@link java.lang.ClassLoader}.  The class	loader repository is used by the forms of the	<code>createMBean</code> and <code>instantiate</code> methods	in the {@link javax.management.MBeanServer MBeanServer}	interface that do not have an explicit loader parameter.  It	is also used by the <code>MLet</code> class when it does not	find a class in its own set of URLs.</p>       <p>If an MBean implements the interface {@link	javax.management.loading.PrivateClassLoader PrivateClassLoader},	then it is not added to the class loader repository.  The class	{@link javax.management.loading.PrivateMLet PrivateMLet} is a	subclass of <code>MLet</code> that implements	<code>PrivateClassLoader</code>.</p>     <p id="spec">    @see <a href="{@docRoot}/../technotes/guides/jmx/">      Java Platform documentation on JMX technology</a>,    in particular the     <a href="{@docRoot}/../technotes/guides/jmx/JMX_1_4_specification.pdf">      JMX Specification, version 1.4(pdf).</a>       @since 1.5</BODY></HTML>
