[sam1]

hi,

can a server and client application communicate using strings. for example say server sends ok and error for each request received.......

thanks

depending on what you mean by "send", of course.
That's pretty much how 99% of network protocols work (simplified of course, the actual stuff that's sent is a lot more complex in many cases).

That's how AOL's protocol (TOC) works.

String msg = "this is a message";

//write it out
out.writeBytes(msg);

//recipient reading back in
byte[] bytes = new byte[in.available()];
in.readFully(bytes);

String incoming = new String(bytes);
