| 53 | * This class represents the meta data for ModelMBeans. Descriptors have been |
| 54 | * added on the meta data objects. |
| 55 | * <P> |
| 56 | * Java resources wishing to be manageable instantiate the ModelMBean using the |
| 57 | * MBeanServer's createMBean method. The resource then sets the ModelMBeanInfo |
| 58 | * and Descriptors for the ModelMBean instance. The attributes and operations |
| 59 | * exposed via the ModelMBeanInfo for the ModelMBean are accessible |
| 60 | * from MBeans, connectors/adaptors like other MBeans. Through the Descriptors, |
| 61 | * values and methods in the managed application can be defined and mapped to |
| 62 | * attributes and operations of the ModelMBean. |
| 63 | * This mapping can be defined during development in a file or dynamically and |
| 64 | * programmatically at runtime. |
| 65 | * <P> |
| 66 | * Every ModelMBean which is instantiated in the MBeanServer becomes manageable: |
| 67 | * its attributes and operations |
| 68 | * become remotely accessible through the connectors/adaptors connected to that |
| 69 | * MBeanServer. |
| 70 | * A Java object cannot be registered in the MBeanServer unless it is a JMX |
| 71 | * compliant MBean. |
| 72 | * By instantiating a ModelMBean, resources are guaranteed that the MBean is |
| 73 | * valid. |
| 74 | * |
| 75 | * MBeanException and RuntimeOperationsException must be thrown on every public |
| 76 | * method. This allows for wrapping exceptions from distributed |
| 77 | * communications (RMI, EJB, etc.) |
