Communicating with Servers prob (Java)

seamus

Right, I'm just fiddling around with some code, Sockets and whatnot, and basic debugging has shown me that everything works, except that the Server doesn't know when I've finished transmitting.

So for example, say I was communicating with a POP server, I send it the String "USER seamus". Then nothing. I get no response from the server at all. And the server is coconnected with me because I get the "+OK server.blah.blah POP3 ready". I know when I do this myself at a terminal, the server does nothing until I hit Carriage Return.

But appending a "\n" to the String does nothing. And the BufferedWriter.newLine() method does nothing either.

I'm sure this is very simple. Do I just have to append some byte to the String?

I dont know anything about socket functions in Java... but try a "\r\n".

Have you tried "\r\n" ? ie carriage return - linefeed

Its been a long time, but I seem to recall needing to do a buffer flush after each string was sent to ensure it is acutally sent rather than cached...

i bet i'm totally off the mark here but would the unicode for return work?

Last time I was doing socket stuff like this was in perl. I did something like:

print $socket "$username".chr(250).chr(4);

Dunno if that's helpful to you seamus.

Cheers all, marauder was right. You have to send the line (with the newline char) and then flush the Stream.
