错在哪里呀（简易聊天程序）？？？

[wkcgy]

这是Client端。
import java.awt.*;
import java.io.*;
import java.awt.event.*;
import java.io.IOException;
import java.net.*;

public class Client extends Frame {

TextField tf = new TextField();
TextArea ta = new TextArea();
Socket s = null;

DataOutputStream dos = null;

public void luanchFrame() {
this.setSize(500, 300);
this.setResizable(false);
this.add(ta, BorderLayout.NORTH);
this.add(tf, BorderLayout.SOUTH);
this.setVisible(true);
tf.addActionListener(new TfListener());
this.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
disConnect();
System.exit(0);
}
});
}
public static void main(String[] args) {
Client c = new Client();
c.luanchFrame();
c.connectToServer();
}

public void disConnect() {
try {
dos.close();
s.close();
} catch (IOException e) {
e.printStackTrace();
}
}

public void connectToServer() {
try {
s = new Socket("127.0.0.1", 8888);
dos = new DataOutputStream(s.getOutputStream());
System.out.println("connect");
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}

public class TfListener implements ActionListener {

public void actionPerformed(ActionEvent e) {
String tfString = tf.getText();
ta.setText(ta.getText() + tfString + '\n');
tf.setText("");
try {
dos.writeUTF(tfString);
dos.flush();

} catch (IOException e1) {
e1.printStackTrace();
}
}
}
}



这是Server端。

import java.io.IOException;
import java.io.*;
import java.net.*;

public class Server {

public static void main(String[] args) {
try {
ServerSocket ss = new ServerSocket(8888);
Socket s = ss.accept();
System.out.println("connect to server");
DataInputStream dis = new DataInputStream(s.getInputStream());
String str = dis.readUTF();
System.out.println(str);
dis.close();

} catch (IOException e) {
e.printStackTrace();
}
}
}
在Client端每当输入超过两条语句以后在CLient端就会报错具体内容如下！！！

try
{
while(true)
{
Soceket s= ss.accept();
DataInputStream dis = new DataInputStream(s.getInputStream());
String str = dis.readUTF();
System.out.println(str);
dis.close();
}

}
catch(Exception e){}

你应该及时关掉Socket s.close()
还有ServerSocket ss.close()

[lodachi]

ServerSocket ss = new ServerSocket(8888);
Socket s = ss.accept();
System.out.println("connect to server");
DataInputStream dis = new DataInputStream(s.getInputStream());
String str = null;
while((str = dis.readUTF())!=null){
System.out.println(str);
}
dis.close();

[lodachi]

上面不对

ServerSocket ss = new ServerSocket(8888); 
Socket s = ss.accept(); 
System.out.println("connect to server"); 
DataInputStream dis = new DataInputStream(s.getInputStream()); 
String str = null;
 while(true){ 
if((str = dis.readUTF())!=null)
System.out.println(str);
 } 
dis.close();

Server端每次只收到一条消息就close了，当然不能再收第二条消息。在Server端加个循环就可以了。
