Thread: Problems with Sockets

I'm having some trouble with sockets not communicating properly. I wrote out some example code to try to target the problem but it's only confused me further.

I wrote two example classes, TestServer and TestClient.

My TestServer contains:
BufferedReader in = new BufferedReader(new

InputStreamReader(ns.getInputStream()));
while (true) {
System.out.println((in.readLine()));
}

and my TestClient contains:

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
while (true) {
out.write("ss\n");
}

then it works fine, constantly outputting ss.

But if TestClient is as follows:

BufferedWriter out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
BufferedReader input = new BufferedReader(new InputStreamReader(System.in));
while (true) {
String ss = input.readLine();
out.write(ss+"\n");
}

Then the Server doesn't receive anything.

I have no idea what's going on and would greatly appreciate any help.

I've had limited success using flush(). Messages now get through, but I still lose information, particularly when several messages are queued in a row.

Good news is: I seem to have fixed the problem.
Bad news is: I'm not really sure how.
