40 * This interface must be implemented by the ModelMBeans. An implementation of this interface
41 * must be shipped with every JMX Agent.
42 * <P>
43 * Java resources wishing to be manageable instantiate the ModelMBean using the MBeanServer's
44 * createMBean method. The resource then sets the ModelMBeanInfo (with Descriptors) for the ModelMBean
45 * instance. The attributes and operations exposed via the ModelMBeanInfo for the ModelMBean are accessible
46 * from MBeans, connectors/adaptors like other MBeans. Through the ModelMBeanInfo Descriptors, values and methods in
47 * the managed application can be defined and mapped to attributes and operations of the ModelMBean.
48 * This mapping can be defined during development in an XML formatted file or dynamically and
49 * programmatically at runtime.
50 * <P>
51 * Every ModelMBean which is instantiated in the MBeanServer becomes manageable:
52 * its attributes and operations
53 * become remotely accessible through the connectors/adaptors connected to that MBeanServer.
54 * A Java object cannot be registered in the MBeanServer unless it is a JMX compliant MBean.
55 * By instantiating a ModelMBean, resources are guaranteed that the MBean is valid.
56 * <P>
57 * MBeanException and RuntimeOperationsException must be thrown on every public method. This allows
58 * for wrapping exceptions from distributed communications (RMI, EJB, etc.). These exceptions do
59 * not have to be thrown by the implementation except in the scenarios described in the specification
60 * and javadoc.
