| * A simple test of the naming service. |
| * |
| * The main class of the GNU Classpath transient naming service is |
| * {@link gnu.CORBA.NamingService}. This class must be started |
| * before starting this example. |
| * |
| * This example should interoperate as with GNU Classpath naming |
| * service, as with Sun Microsystems transient and persistent |
| * naming services, included in releases 1.3 and 1.4 (tnameserv and |
| * orbd). To work with this example, the naming service must |
| * be started on the local host, at the port 900. |
| * |
| * The persistent naming service is currently under development. |
