线程“main”java.net.ConnectException中的exception：连接被拒绝：连接

我正在尝试使用套接字连接并使用netbeans在我的Windows 7中发送文件，但是我收到此错误：

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.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:337) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:198) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:180) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:157) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:391) at java.net.Socket.connect(Socket.java:579) at java.net.Socket.connect(Socket.java:528) at java.net.Socket.(Socket.java:425) at java.net.Socket.(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(); } } } 

这是我的客户端类：

 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(); } } 

我该如何解决这个问题，谢谢？
