| /** |
| * The main executable class of the game manager server. |
| * |
| * The manager address server returns the IOR address string of the game |
| * manager. Hence the user does not need to enter the rather long IOR address |
| * string and only needs to specify the host and port of the machine where the |
| * game manager is running. |
| * |
| * The manager address server starts the main game manager as well. |
| * |
| * This server acts as a HTTP server that always returns the same response. This |
| * primitive functionality is sufficient for its task. |
| * |
| * The more complex CORBA applications should use the name service instead. We |
| * do not use the name service as this would require to start additional |
| * external application, specific for the different java platforms. |
