Using ServerSocket class (page 2)
*
* ... Continuation from page 1
* 
* Then we arrange an indefinite loop listening for client requests
*
* When a client sends a request-message to the specified host and port number
* server program accepts this request with accept method
* that returns client socket established on the server side for this connection.
*
* Then, we can open input/output streams to the socket.
* We use Filter Streams in the example allowing us to simplify the code
* by directly working with strings, not bytes.
* It is expected that the same type of streams are open on the client side.
*
* We read a string of a client request from the input stream
* and call serviceMethod(clientRequest) method to provide a service.
*
* The service is very simple: we just return input string.
* But in real world it could be sophisticated analysis of client request
* with plenty of calls to different method-services.
*
* Then we send response string back to the client using PrintStream.
*
* We close the client connection, but keep alive the server socket
*
* That's the end of the while loop, so the program is back expecting
* another client request to accept.
