| 42 | * GetStatus ZOO Service : |

| 43 | * This service is used in the ZOO-Project to get information about Services |

---|
| 45 | * cached by the ZOO-Kernel before calling effectively the Service, then |
---|
| 46 | * will access the shared memory space created by the Kernel to extract the |
---|
| 47 | * current status of the running Service. Using a simple XSL file it will |
---|
| 48 | * finally produce the final ExecuteResponse including the updated |
---|
| 49 | * percentCompleted attribute of the ProcessStarted node of the cached |
---|
| 50 | * document if any (so if the Service is currently running) else it will |
---|
| 51 | * return the final ExecuteResponse stored on the Server file system. |
