| 41 | * We do the same test with a number of different operations: |
| 42 | * |
| 43 | * - A plain operation that is directed to the managed resource in the |
| 44 | * usual way. We give it some parameters so we can test that the |
| 45 | * class loading logic for signature parameters is reasonable. |
| 46 | * |
| 47 | * - An operation (removeNotificationListener) that is directed to the |
| 48 | * RequiredModelMBean itself. We use this particular operation because |
| 49 | * it will throw an exception, which allows us to check that it did in |
| 50 | * fact execute. |
| 51 | * |
| 52 | * - An operation (load()) that has the same signature as a |
| 53 | * RequiredModelMBean operation but is directed to the resource |
| 54 | * because of a "class" field in the descriptor. |
| 55 | * |
| 56 | * - An operation (store()) that has the same signature as a |
| 57 | * RequiredModelMBean operation but is directed to the resource |
| 58 | * because of a "targetObject" field in the descriptor. |
| 59 | * |
| 60 | * In each case we check that the operation does not work if it is not |
| 61 | * in the ModelMBeanInfo, and does work if it is. |
