public interface ModelMBean extends DynamicMBean, PersistentMBean, ModelMBeanNotificationBroadcaster
Java resources wishing to be manageable instantiate the ModelMBean using the MBeanServer's createMBean method. The resource then sets the ModelMBeanInfo (with Descriptors) for the ModelMBean instance. The attributes and operations exposed via the ModelMBeanInfo for the ModelMBean are accessible from MBeans, connectors/adaptors like other MBeans. Through the ModelMBeanInfo Descriptors, values and methods in the managed application can be defined and mapped to attributes and operations of the ModelMBean. This mapping can be defined during development in an XML formatted file or dynamically and programmatically at runtime.
Every ModelMBean which is instantiated in the MBeanServer becomes manageable: its attributes and operations become remotely accessible through the connectors/adaptors connected to that MBeanServer. A Java object cannot be registered in the MBeanServer unless it is a JMX compliant MBean. By instantiating a ModelMBean, resources are guaranteed that the MBean is valid.
MBeanException and RuntimeOperationsException must be thrown on every public method. This allows for wrapping exceptions from distributed communications (RMI, EJB, etc.). These exceptions do not have to be thrown by the implementation except in the scenarios described in the specification and javadoc.

void setModelMBeanInfo(ModelMBeanInfo inModelMBeanInfo) throws MBeanException, RuntimeOperationsException
If the ModelMBean is currently registered, this method throws
RuntimeOperationsException wrapping an
inModelMBeanInfo- The ModelMBeanInfo object to be used by the ModelMBean.
MBeanException- Wraps a distributed communication Exception.
IllegalArgumentExceptionif the MBeanInfo passed in parameter is null.
IllegalStateExceptionif the ModelMBean is currently registered in the MBeanServer.
void setManagedResource(Object mr, String mr_type) throws MBeanException, RuntimeOperationsException, InstanceNotFoundException, InvalidTargetObjectTypeException
mr- Object that is the managed resource
mr_type- The type of reference for the managed resource. Can be: ObjectReference, Handle, IOR, EJBHandle, RMIReference. If the MBeanServer cannot process the mr_type passed in, an InvalidTargetTypeException will be thrown.
MBeanException- The initializer of the object has thrown an exception.
RuntimeOperationsException- Wraps an IllegalArgumentException: The managed resource type passed in parameter is null.
InstanceNotFoundException- The managed resource object could not be found
InvalidTargetObjectTypeException- The managed resource type cannot be processed by the ModelMBean or JMX Agent.
