public BasicMBeanRegistry(MBeanServer server,
                          String defaultDomain)

Constructs a new BasicMBeanRegistry.

Method Detail

public ObjectInstance registerMBean(Object object,
                                    ObjectName name,

                                    NotCompliantMBeanException

Description copied from interface: MBeanRegistry

Register an mbean.

This method is invoked by the MBeanServer for createMBean() and registerMBean().

The object name passed maybe unqualified.

The map is a user definable string to value object map for holding information against a registered object. This map may contain metadata related to the registration, such as registration date/time, classloader references, etc.

Pass JMI_DOMAIN in both the key and values of the values map to get access to the reserved domain. It is removed from the map during registration to save memory.

Pass CLASSLOADER in the values map to set the context classloader

Other values are user definable and can be retrieved using the getValue(ObjectName,String) method.

Specified by:

registerMBean in interface MBeanRegistry

Parameters:

object - the mbean to register.

name - the object name to assign to the mbean.

valueMap - a map of other information to include in the registry

Returns:

an object instance for the registered mbean

Throws:

InstanceAlreadyExistsException - when the object name is already registered.

MBeanRegistrationException - when an exception is raised during preRegister for the mbean.

NotCompliantMBeanException - when the passed object is a valid mbean.
