Socket problem

[socket]

Hi,
der Socket schließt zu früh was kann ich da gegen machen.
Mein code:

package Fehler;

import java.awt.BorderLayout;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTextArea;
import javax.swing.JTextField;


import java.io.ObjectOutputStream;

public class Test extends Thread implements ActionListener{
	JFrame f = new JFrame("Test");
	JTextField ipTF,clientportTF,serverPortTF,messageTF;
	SendData sendData=null;
	public Test(){
		f.setSize(100,50);
		f.setLayout(new GridLayout(2,2));
		ipTF = new JTextField("");
		f.add(ipTF);
		clientportTF = new JTextField();
		f.add(clientportTF);
		serverPortTF = new JTextField();
		serverPortTF.addActionListener(this);
		f.add(serverPortTF);
		messageTF = new JTextField();
		messageTF.addActionListener(this);
		f.add(messageTF);
		f.setVisible(true);
		sendData = new SendData(6889);
		sendData.start();
	}

	public static void main(String args[]){
		new Test();
	}

	public void actionPerformed(ActionEvent e) {
		// TODO Auto-generated method stub
		if(e.getSource()==serverPortTF){
			sendData.stop();
			sendData=new SendData(Integer.parseInt(serverPortTF.getText()));
			sendData.start();
		}else{
			Socket socket;
			try {
				socket = new Socket(ipTF.getText(),Integer.parseInt(clientportTF.getText()));
			ObjectOutputStream oos = new ObjectOutputStream(new BufferedOutputStream(socket.getOutputStream()));
			oos.writeObject(messageTF.getText());
			oos.flush();
			oos.close();
			ObjectInputStream ois = new ObjectInputStream(new BufferedInputStream(socket.getInputStream()));
			Object o=ois.readObject();
			System.out.println(o);
			ois.close();
			socket.close();

		}
	}
}
class SendData extends Thread{
	int port=6889;
	public SendData(int port){
		this.port=port;
	}

	public void run(){
		try {
			ServerSocket s = new ServerSocket(port);
			Socket socket=s.accept();
			ObjectInputStream ois = new ObjectInputStream(new BufferedInputStream(socket.getInputStream()));
			Object o=ois.readObject();
			ois.close();
			System.out.println(o);
			ObjectOutputStream oos = new ObjectOutputStream(new BufferedOutputStream(socket.getOutputStream()));
			oos.writeObject("Bekommene nachricht:"+o);

		} catch (IOException e) {

Fehlermeldung vom Server

cool
java.net.SocketException: Socket is closed
	at java.net.Socket.getOutputStream(Socket.java:799)
	at Fehler.SendData.run(Test.java:104)

das cool ist der text den ich gesendet habe. Er kommt also beim server an nur das request vom server geht nicht. Was mache ich falsch?

       ois.close();

Mach das mal weg. Wenn du Stream schließt, kann es gut sein, dass dann der ganze Socket geschlossen wird.
