Java - buffer hangs.

post #1 of 5
Thread Starter 
Im tring to may a client - server program. the client connects to the server fine,

BufferedReader input = new BufferedReader(new InputStreamReader(socket.getInputStream()));
PrintStream output = new PrintStream(socket.getOutputStream());

try
{
Thread.sleep(100);
}catch(Exception e)
{
}

System.out.println("Reading Buffer");
String buffer = input.readLine();
System.out.println("Read Buffer");

"Read Buffer" does not get displayed, it just hangs there.

What does the server code look like? Make sure it's sending something into its output stream and also make sure to Flush() the stream on the server otherwise it may not send data right away.

thanks for the reply, i havent used flush anywhere. the client sends a string output.print("1234");

With networking code you usually have to call Flush on the output stream, otherwise it just holds the data in an internal buffer until there's a lot and then it'll send it. Flush tells it to send now.

I got it to work, i had a output back from the server to tell the client the message was recieved. so i commented that out and it was ok.

but i cant use the output and input as up and down as i expected.
