Problem with echo server and client.

HAllo.

I am staring and staring at my code below but can not work out what i have don wrong.
A client connects successfully to the server and gets the message "Echoserver running" from the server but when writing to the server nothing happens. A hint to make me locate the logical flaw would be nice!

Client:



Server:

1) Change the == on line 50 of EchoClient to !=

2) Don't println to a socket. Instead of using println(), use print, explicitly print out the line separator you want, and manually flush:


After these changes your echo server and client are working just fine with me.

Thank you for the reply.
The changes does not make it work for me. I changed to use print and adding "\r\n" and flushing instead of println when to socket streams.

Did you also change the == into != ?

Yes. But of course I should also remember to move the System.out.println inside the while loop when changing == to !=. And now it works )
Thank you very much for the help. Should have asked a few days ago ! Especially the problem with println was tricky I think. I am nos sure that I understand why the == does not work. I will think a little more about it.

readLine() will return null when you've already read all there is to read. So the loop was executing exactly zero times, because the condition was false from the start.
