Java / JSP发送TCP数据包并等待响应

Question

我正在尝试发送TCP数据包。 它正确地发送到服务器，但是发送者没有得到响应（服务器正确地发送了响应）。 客户端甚至不处理发送数据包后的代码...

 Socket socket = new Socket (ip, port);

 PrintWriter mOut = new PrintWriter(socket.getOutputStream(), true);  
 mOut.print("DSPSYSSTS");

 //Everything works fine until here

 BufferedReader mIn = new BufferedReader (new InputStreamReader (socket.getInputStream ()));
 String fromClient = mIn.readLine();
 out.println ("Client Message: " + fromClient);

 mOut.close();
 mIn.close ();      
 socket.close ();

JSP不会打印输入，并且会永远加载。 怎么了？

在下面的代码中返回systemRequest.request字符串

ReadSpoolFile readSplf = new ReadSpoolFile(splfArray.get(0));
String splfContent = readSplf.read();

GetSystemStatus getSysSts = new GetSystemStatus();
String systemStatus = getSysSts.get(splfContent);
return systemStatus + "\r\n";

服务器端响应：

String response = systemRequests.request(message, SystemRequests.SILENT_OFF);

ChannelBuffer mCbResponse;

if(response != null){
mCbResponse = ChannelBuffers.copiedBuffer(response.getBytes());
mChannel.write(mCbResponse);    //<------Write response

尝试这个：

mOut.print("DSPSYSSTS");
mOut.flush();
