* 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.) |
