| * Sample Service Level Locator |
| * ServiceLevelDataLocator is configured as a Service level Data Locator |
| * for the Sample ServiceLevelDataLocatorDemoService service. |
| * |
| * The sample Data Locator is only for the purpose of demostrating an implementation of |
| * user-defined Service Level Data Locator, the actual data retrieval code is not implemented. |
| * In the example, a empty Data array is returned for Policy and Schema data retrieval |
| * request, and a null Data array is returned for WSDL data retrieval. |
| * |
| * Note: Empty Data array means Data Locator understood the request, however data |
| * is not available for the Dialect; a null data array means Data Locator does not understand |
| * the request. |
| * |
| * Run {@link DemoServiceLevelDataLocator} client code to invoke this sample data locator. |
