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
.
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 the
ClassLoaderRepository . |
Class | Description |
---|---|
DefaultLoaderRepository | Deprecated.
Use
MBeanServer.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 the
MLET tag. |
PrivateMLet |
An MLet that is not added to the
ClassLoaderRepository . |
