Java inputstream never leaves

I'm coding a server app in Java.

I wrote data receive part in server like this:
String s;
in = new DataInputStream(client.getInputStream());

And below this code after some other processings...
while ((i = in.read()) != -1) {
s = s + (char) i;
}
System.out.println("OK! We received data part");

This code never prints out "OK! We received data part" till I close connection from client!
Why?

So how can I read data from inputStream?

Thanks from now!

read is blocking call, will wait untill it receives data from client

You should define boundry of the request and read till that point.

b. you close the OutputStream of client
How? My client is coded in VB6.

And is there another call or reading method which can leave in inputstream?

Not sure how you can close output fd in VB. If you are expecting data from the client in terms of line, you can use readLine() function

Assuming that from VB program, you are trying to send the commands line by line,
i would suggest to use the following:

String command = in.readLine();
// Work on the command

Do NOT read char by char
