我正在尝试进行套接字连接并使用 netbeans 在我的 Windows 7 内发送文件，但出现此错误：

Exception in thread "main" java.net.ConnectException: Connection refused: connect
    at java.net.DualStackPlainSocketImpl.connect0(Native Method)
    at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:69)

    at java.net.Socket.<init>(Socket.java:208)
    at socket.TCPclient.main(TCPclient.java:22)
Java Result: 1

这是我的服务器类：

package socket;

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

public class TCPserver {
  public static void main (String [] args ) throws IOException {
    // create socket
    ServerSocket servsock = new ServerSocket(13267);
    while (true) {
      System.out.println("Waiting...");

      Socket sock = servsock.accept();
      System.out.println("Accepted connection : " + sock);

      // sendfile
      File myFile = new File ("source.pdf");
      byte [] mybytearray  = new byte [(int)myFile.length()];
      FileInputStream fis = new FileInputStream(myFile);
      BufferedInputStream bis = new BufferedInputStream(fis);
      bis.read(mybytearray,0,mybytearray.length);
      OutputStream os = sock.getOutputStream();
      System.out.println("Sending...");
      os.write(mybytearray,0,mybytearray.length);
      os.flush();
      sock.close();
      }
    }
}

这是我的客户类：

package socket;
import java.io.BufferedOutputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.Socket;

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

public class TCPclient{
  public static void main (String [] args ) throws IOException {
    int filesize=6022386; // filesize temporary hardcoded

    long start = System.currentTimeMillis();
    int bytesRead;
    int current = 0;
    // localhost for testing
    Socket sock = new Socket("127.0.0.1",13267);
    System.out.println("Connecting...");

    // receive file
    byte [] mybytearray  = new byte [filesize];
    InputStream is = sock.getInputStream();
    FileOutputStream fos = new FileOutputStream("source-copy.pdf");
    BufferedOutputStream bos = new BufferedOutputStream(fos);
    bytesRead = is.read(mybytearray,0,mybytearray.length);
    current = bytesRead;

    // thanks to A. Cádiz for the bug fix
    do {
       bytesRead =
          is.read(mybytearray, current, (mybytearray.length-current));
       if(bytesRead >= 0) current += bytesRead;
    } while(bytesRead > -1);

    bos.write(mybytearray, 0 , current);
    bos.flush();
    long end = System.currentTimeMillis();
    System.out.println(end-start);
    bos.close();
    sock.close();
  }
}

怎么解决这个问题，谢谢
