Create A Server Which Sends Clients Connected To It Its Local Time

I'm trying to create a server which sends the clients connected to it its local time. Looking at a few tutorials I've managed to connect the clients to the server, but can't send data to the clients. I've successfully done easier examples, without threading. I guess the problem might be im me not knowing what exceptions are for.

Client: When running the code "AAAAAAA" does execute but "BBBB" doesn't, so I guess the problem should be in fraseRecibida = entradaDesdeServidor.readLine();

import java.io.*;
import java.net.*;
import java.util.Scanner;
public class Client {
public static void main(String[] args) throws Exception{
String fraseRecibida;

[code]....

I don't understand the exceptions, maybe I should give them a look before continuing with sockets. Being frank I'm not really sure why the while(true) is there.

import java.io.*;
import java.net.*;
import java.util.Calendar;
public class ServerThread extends Thread{
Socket socket;
ServerThread(Socket socket){
this.socket = socket;

[code].....
