Firefox tcp socket.send () data transfer cannot be retrieved until socket is closed

Question

I am trying to send some data from Firefox to a java desktop application. So my java class works as a server, and the Firefox script works as a client. When I test it using another java class that is client.javadata successfully sent to server.java, when ever, when I use this firefox script to send data, it actually connects to the .but server does send("text");not work in real time. I mean sever shows the received data when I close the socket socket.close();. but I know server.javathere is no problem with the code .

this does not work

setTimeout(function(){socket.send("i'm firefox");},5000); // because socket isn't closed yet

this job

setTimeout(function(){socket.send("i'm firefox");},5000);
setTimeout(function(){socket.close();},6000); 

but I really don't want to close the socket because I want to send a lot of data one by one.

here is the full code tested on notepad [-browser]

var tcpSocket = Cc["@mozilla.org/tcp-socket;1"].createInstance(Ci.nsIDOMTCPSocket);
var socket = tcpSocket.open("127.0.0.1", 5000);

setTimeout(function(){socket.send("i'm firefox");},5000);
//setTimeout(function(){socket.close();},8000);// i'm firefox text retrieve by server when run this line / when close the socket.

I think java code doesn't matter. but here it is.

I ask, why do I need to close the socket to send data? and how can I send data without closing the socket?

update

I made a Gif to show my problem here, you can see data not sending in real time, but when the socket is closed, all data is reset.

It really works. Your data will be received, but you expect a new line to print your received messages:

while ((inputLine = in.readLine()) != null) {
    System.out.println("Server: " + inputLine);
    out.println(inputLine);

    if (inputLine.equals("Bye.")) {
        break;
    }
}

. , :

var tcpSocket = Cc["@mozilla.org/tcp-socket;1"].createInstance(Ci.nsIDOMTCPSocket);
var socket    = tcpSocket.open("127.0.0.1", 5000);

function sendMessage(msg){
    socket.send(msg + "\n");
}

setTimeout(function(){
    sendMessage("hi mark");
},3000);

setTimeout(function(){
    sendMessage("hi johnny");
},5000);
