Class SimpleServer

java.lang.Object

simplenlg.server.SimpleServer

All Implemented Interfaces:

Runnable

public class SimpleServer
extends Object
implements Runnable

SimpleServer is a program that realises xml requests.

Author:

Roman Kutlak.

The program listens on a socket for client connections. When a client connects, the server creates an instance of RealisationRequest that serves the client.

The RealisationRequest parses the xml structure and sends back corresponding surface string.

The server port can be specified as the first parameter of the program; 50007 is used by default.

Typing exit will terminate the server.
