hi marc,

the server code is fine - you may test it by connecting to your server with a telnet client and then typing a line.

however, the client expects the server to send a welcome string once they are connected. it hangs at:


because the server also waits for the client to send something, which doesn't happen!

check this out.
like this, there is no loop or so, but you can see what you type in at the client will be received by the server. Now just do whatever you wanted to do with the data coming in at the server.
One caveat. When you run the client from an IDE, you might get problems because sometimes, STDIN (java.lang.System.in) is not readable (BufferedReader.readLine() in the client then returns immediately). I have this problem when I use my Netbeans IDE. Netbeans uses Ant for running a project, and by default you don't have a console (there is some kind of switch you can set in the "java" ant task, it's attribute "fork" which you probably have to set to "true" if you wanna use the Netbeans console as STDIN; see manual: http://ant.apache.org/manual/index.html). I recommend testing from the command line.

Both of you, welcome to JavaRanch!

And I do have to let you know that you're both in violation of the JavaRanch policy on display names. It requires that you use a full, real (sounding) first and last name for your display name. Joke names and "handles" aren't acceptable at the Ranch. You can change your display names here; please do so right away. Thanks for your cooperation.
