[Newbies] simple server?

[Don McLane]

I'm trying to learn to write network objects in squeak.  I read the
chapter "Networking Squeak" by Parsia, Kerimbaev, and Spoon, from Mark
Guzdials book.  But I wanted to start at a more basic level.

My first attempt is to write the simplest possible server.  This server
should wait for a connection, then print the first line sent to it,
finally close.  Unfortunately, it gets a "primitive failed" error.  I
got the same result on XP and Vista.  Here's my code:

| serverSocket connectionSocket |
Socket initializeNetwork.
serverSocket := Socket newTCP.
serverSocket listenOn: 8080.
connectionSocket := serverSocket accept.
Transcript show: (connectionSocket upToAll: String crlf).
connectionSocket close.
serverSocket close.

I found some old code for the PWS and looked around.  It makes a
ServerSocket object, but I can't find that class in my image (3.9-7067).

If I do get a server socket to return a connection socket, is there a
way to convert that socket into a SocketStream?

Can anyone get me un-stuck?  I've been trying to get past this for a
couple evenings now.

Thanks much,
Don
