/**

 * This is the server class that handles the client requests,

 * delegating the functionality to the {@link DemoServant}.

 *

 * When starting, the server writes the IOR.txt file into the current

 * folder. With the information, stored in this file, the server

 * should be reachable over Internet, unless blocked by security tools.

 *

 * This code is tested for interoperability with Sun Microsystems

 * java implementation 1.4.2 (08.b03). Server, client of both can

 * be started either on Sun's or on Classpath CORBA implementation,

 * in any combinations.

 *

 * BE SURE TO START THIS SERVER BEFORE STARTING THE CLIENT.
