ObjectInstance createMBean(String className, ObjectName name) throws ReflectionException, InstanceAlreadyExistsException, MBeanRegistrationException, MBeanException, NotCompliantMBeanException
MBeanServerConnection
Instantiates and registers an MBean in the MBean server. The
MBean server will use its Default Loader
Repository
to load the class of the MBean. An object name is
associated to the MBean. If the object name given is null, the
MBean must provide its own name by implementing the MBeanRegistration
interface
and returning the name from the preRegister
method.
This method is equivalent to createMBean(className, name, (Object[]) null, (String[])
