一直有个问题没想到解决办法，代码在eclipse上面运行tcp练习时出现SocketException异常 ，但是在其他在命令行中能够正常运行。不知道为什么在eclipse中就不能运行呢？这和tcp协议有关系吗？练习udp的时候能在eclipse中运行。还是说这段代码有什么问题？
import java.io.*;
import java.net.*;
class TextClient{
public static void main(String[] args)throws Exception{
  Socket s=new Socket("127.0.0.1",10009);
  BufferedReader bufr=
    new BufferedReader(new FileReader("UdpDemo.java"));
  PrintWriter out=new PrintWriter(s.getOutputStream(),true);
  String line=null;
  while((line=bufr.readLine())!=null){
   out.println(line);
  }
  s.shutdownOutput();//关闭客户端输出流，相当于给流中加入一个结束标记
  BufferedReader bufIn=
    new BufferedReader(new InputStreamReader(s.getInputStream()));
  String str=bufIn.readLine();
  System.out.println(str);
  bufr.close();
  s.close();
}
}
class TextServer{
public static void main(String[] args) throws Exception {
  ServerSocket ss=new ServerSocket(10009);
  Socket s=ss.accept();
  String ip=s.getInetAddress().getHostAddress();
  System.out.println(ip+"......is connected");
  BufferedReader bufIn=
    new BufferedReader(new InputStreamReader(s.getInputStream()));
  PrintWriter out=new PrintWriter(new FileWriter("server.txt"),true);
  String line=null;
  while((line=bufIn.readLine())!=null){
   out.println(line);
  }
  PrintWriter pw=new PrintWriter(s.getOutputStream(),true);
  pw.println("上传成功");
  out.close();
  s.close();
  ss.close();
}
}
public class UploadText {
public static void main(String[] args) {
}
}
我先运行TextServer，再运行TextClient，发生下面结果
127.0.0.1......is connected
