Java - GUI crashes [Socket]

12/02/12 7:52

salve a tutti...Vorrei porvi un problema stranissimo.
dopo aver definito la classe Server .....

ServerSocket server=new ServerSocket(port);
public static List<Client> clientlist; 
for(;;){
    Socket s=server.accept();
    ServerIOChannel channel=new ServerIOChannel(s);
    channel.start();
}

....la classe ....

public class ServerIOChannel implements Runnable(){
    private Socket sock;  
    private ObjectOutputStream oos;
    private ObjectIntputStream ois;   
    private boolean running=false;
    public ServerIOChannel(Socket sock) throws Exception{
         this.sock=sock;
         ois=new ObjectInputStream(this.sock.getInputStream());
         oos=new ObjectOutputStream(this.sock.getOutputStream());
         Thread t=new Thread(this);
         t.start();     
    }

     @Override
     public void run(){
          running=true; 
          while(running){
                String receivedline=(String) ois.readObject();
                if(receivedline.equals("sendsSerializedObject"){
                    oos.writeObject(Server.list);
                    oos.flush();
                }
          }
     }
}

e le classi [Client] e [ClientIOChannel implements runnable] ---> allo stesso modo

ho notato che quando il client si logga al server va tutto bene ma dopo pochi secondi entra in crash si blocca tutta l'interfaccia grafica.. ho provato ad usare dopo la classe DataOutputStream e DataInputStream e non si blocca..come mai ? come potrei risolvere questo problema..ho necessità di usare l ObjectOutputStream per trasferire oggetti...
Questo è l'errore che mi visualizza:

	at java.awt.EventQueue.accesssalve a tutti...Vorrei porvi un problema stranissimo.

dopo aver definito la classe Server .....

ServerSocket server=new ServerSocket(port);
public static List<Client> clientlist; 
for(;;){
    Socket s=server.accept();
    ServerIOChannel channel=new ServerIOChannel(s);
    channel.start();
}




....la classe ....

public class ServerIOChannel implements Runnable(){
    private Socket sock;  
    private ObjectOutputStream oos;
    private ObjectIntputStream ois;   
    private boolean running=false;
    public ServerIOChannel(Socket sock) throws Exception{
         this.sock=sock;
         ois=new ObjectInputStream(this.sock.getInputStream());
         oos=new ObjectOutputStream(this.sock.getOutputStream());
         Thread t=new Thread(this);
         t.start();     
    }

     @Override
     public void run(){
          running=true; 
          while(running){
                String receivedline=(String) ois.readObject();
                if(receivedline.equals("sendsSerializedObject"){
                    oos.writeObject(Server.list);
                    oos.flush();
                }
          }
     }
}




e le classi  [Client] e [ClientIOChannel implements runnable] ---> allo stesso modo



ho notato che quando il client si logga al server  va tutto bene ma dopo pochi secondi entra in crash si blocca tutta l'interfaccia grafica.. ho provato ad usare dopo la classe DataOutputStream e DataInputStream e non si blocca..come mai ? come potrei risolvere questo problema..ho necessità di usare l ObjectOutputStream per trasferire oggetti... 

Questo è l'errore che mi visualizza:
