* This class is the implementation of a ModelMBean. An appropriate |
|
91 |
* implementation of a ModelMBean must be shipped with every JMX Agent |
|
92 |
* and the class must be named RequiredModelMBean. |
|
93 |
* <P> |
|
94 |
* Java resources wishing to be manageable instantiate the |
|
95 |
* RequiredModelMBean using the MBeanServer's createMBean method. |
|
96 |
* The resource then sets the MBeanInfo and Descriptors for the |
|
97 |
* RequiredModelMBean instance. The attributes and operations exposed |
|
98 |
* via the ModelMBeanInfo for the ModelMBean are accessible |
|
99 |
* from MBeans, connectors/adaptors like other MBeans. Through the |
|
100 |
* Descriptors, values and methods in the managed application can be |
|
101 |
* defined and mapped to attributes and operations of the ModelMBean. |
|
102 |
* This mapping can be defined in an XML formatted file or dynamically and |
|
103 |
* programmatically at runtime. |
|
104 |
* <P> |
|
105 |
* Every RequiredModelMBean which is instantiated in the MBeanServer |
|
106 |
* becomes manageable:<br> |
|
107 |
* its attributes and operations become remotely accessible through the |
|
108 |
* connectors/adaptors connected to that MBeanServer. |
|
109 |
* <P> |
|
110 |
* A Java object cannot be registered in the MBeanServer unless it is a |
|
111 |
* JMX compliant MBean. By instantiating a RequiredModelMBean, resources |
|
112 |
* are guaranteed that the MBean is valid. |
|
113 |
* |
|
114 |
* MBeanException and RuntimeOperationsException must be thrown on every |
|
115 |
* public method. This allows for wrapping exceptions from distributed |
|
116 |
* communications (RMI, EJB, etc.) |

/* |
|
880 |
The requirement to be able to invoke methods on the |
|
881 |
RequiredModelMBean class itself makes this method considerably |
|
882 |
more complicated than it might otherwise be. Note that, unlike |
|
883 |
earlier versions, we do not allow you to invoke such methods if |
|
884 |
they are not explicitly mentioned in the ModelMBeanInfo. Doing |
|
885 |
so was potentially a security problem, and certainly very |
|
886 |
surprising. |
|
887 |
||
888 |
We do not look for the method in the RequiredModelMBean class |
|
889 |
itself if: |
|
890 |
(a) there is a "targetObject" field in the Descriptor for the |
|
891 |
operation; or |
|
892 |
(b) there is a "class" field in the Descriptor for the operation |
|
893 |
and the named class is not RequiredModelMBean or one of its |
|
894 |
superinterfaces; or |
|
895 |
(c) the name of the operation is not the name of a method in |
|
896 |
RequiredModelMBean (this is just an optimization). |
|
897 |
||
898 |
In cases (a) and (b), if you have gone to the trouble of adding |
|
899 |
those fields specifically for this operation then presumably you |
|
900 |
do not want RequiredModelMBean's methods to be called. |
|
901 |
||
902 |
We have to pay attention to class loading issues. If the |
|
903 |
"class" field is present, the named class has to be resolved |
|
904 |
relative to RequiredModelMBean's class loader to test the |
|
905 |
condition (b) above, and relative to the managed resource's |
|
906 |
class loader to ensure that the managed resource is in fact of |
|
907 |
the named class (or a subclass). The class names in the sig |
|
908 |
array likewise have to be resolved, first against |
|
909 |
RequiredModelMBean's class loader, then against the managed |
|
910 |
resource's class loader. There is no point in using any other |
|
911 |
loader because when we call Method.invoke we must call it on |
|
912 |
a Method that is implemented by the target object. |
