Socket中服务器向客服端发送信息的问题

Question

先上代码：
public class ServerThread implements Runnable{
//定义当前线程所处理的Socket
Socket s=null;
BufferedReader bReader=null;
OutputStream os=null;
public ServerThread(Socket s) throws IOException{
this.s=s;
bReader=new BufferedReader(new InputStreamReader(s.getInputStream(),"utf-8"));
}

public void run() {
    // TODO Auto-generated method stub
    String contentString=null;
    System.out.println("进入了");
    try {
        while((contentString=readFromClient())!=null){
            for(Socket s:MyServer.socketList){
                System.out.println(contentString);
                os=s.getOutputStream();
                os.write((contentString+"\n").getBytes("utf-8"));
                os.flush();                                     
            }
        }
        os.close();
        bReader.close();
        s.close();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        System.out.println(e.toString());
    }

}


public String readFromClient(){
    try {
        return bReader.readLine();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        System.out.println("没有接受到任何数据");
        MyServer.socketList.remove(s);
    }
    return null;
}

}

在readLine()执行后已经接受到了客户端的信息，但是在os.write((contentString+"\n").getBytes("utf-8"));这一行直接报错了

报错信息如下：
java.net.SocketException: Software caused connection abort: socket write error
at java.net.SocketOutputStream.socketWrite0(Native Method)
at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:92)
at java.net.SocketOutputStream.write(SocketOutputStream.java:124)
at ServerThread.run(ServerThread.java:29)
at java.lang.Thread.run(Thread.java:619)

什么问题导致的呢，百度了好多都没解决

结贴吧，os=s.getOutputStream();写在while循环里面去了
