Baixei os arquivos do http://www.inf.ufsc.br/~bosco/downloads/Java%206%20CD/ch24/DeitelMessengerCaseStudy/
e implementei o DeitelMessenger
Já está tudo certinho, sem nenhum erro, mas como eu faço pra rodar ele no eclipse?
Onde eu tenho que ir?
Abraços
Estou com vários códigos de instant messenger, mas não sei como roda nenhum deles =x
Alguem dá uma luz please
consegue postar o codigo inteiro aqui ou zipar ele?
Um exemplo de instant messenger que encontrei
Como faço para rodar?
Quando vou em Run As tem escrito “Select Type(? = any character, *= any string,TZ=timeZone”
e em baixo o Servidor e o StressClient
o que isso significa?
import java.net.;
import java.io.;
public class Servidor implements Runnable
{
ServerSocket ss;
public Servidor(int porta) throws Exception{
ss = new ServerSocket(porta);
new Thread(this).start();
System.out.println("Servidor ouvindo na porta:" + porta);
}
public void run(){
try{
while(true){
new TrataCliente(ss.accept()).start();
System.out.println("Mais um cliente atendido!");
}
}catch(Exception e){
e.printStackTrace();
System.exit(1);
}
}
public static void main(String[] args){
try{
new Servidor(1000);
}catch(Exception e){
e.printStackTrace();
System.exit(1);
}
}
}
import java.net.;
import java.io.;
public class StressCliente extends Thread
{
private String server;
private int porta;
public StressCliente(String server, int porta){
this.server = server;
this.porta = porta;
}
public static void main(String[] args){
try{
String server = "localhost";
int porta = 1000;
int numeroDeClientes = 10;
for(int i=0; i < numeroDeClientes; i++){
new StressCliente(server, porta).start();
}
}catch(Exception e){
e.printStackTrace();
}
}
public void run(){
try{
while(true){
Socket s = new Socket(server, porta);
System.out.println("Conectado a " + server + ":" + porta);
ObjectOutputStream oo = new ObjectOutputStream(s.getOutputStream());
oo.writeObject("Soh!");
s.close();
}
}catch(Exception e){
e.printStackTrace();
}
}
}
import java.net.;
import java.io.;
class TrataCliente extends Thread
{
private Socket client;
public TrataCliente(Socket s){
client = s;
}
public void run(){
try{
// aqui vai a sua comunicacao com o cliente
ObjectInputStream oi = new ObjectInputStream(client.getInputStream());
System.out.println("Chegou isso:" + oi.readObject());
client.close();
}catch(Exception e){
e.printStackTrace();
System.exit(1);
}
}
}
Também tem esse, ele até abre um frame:
