/**
 * 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.
