NioServer is a multi-client stateful server written in Scala, using Java NIO and delimited continuations.
This project holds the code used in my "Java NIO" series of blog posts.

The files are in the standard layout, with source files under src/main/scala.
To compile using build.xml and ant, you must set up a
symlink called scala-current that points to the main directory
of your installed copy of scala. Once you have done that, you can use the
following command to compile the application and create a release directory
for it that includes a startup script:
ant build relbin
The following command (with the appropriate
value for the version number N.N.N)
will run EchoServer:
release/nioserver-N.N.N/bin/nioserver
This command will run ThreeQuestionsServer:
release/nioserver-N.N.N/bin/3Qserver
If you get an error about port in use, try changing the port value in
src/main/scala/NioServer.scala and recompiling.
Once the server has started without errors, telnet to it from another window:
telnet localhost 1234
When you type into the telnet window and press enter, your text should be echoed back to you.
To compile without using ant, cd into src/main/scala
and run this command:
scalac -P:continuations:enable *.scala net/jimmc/*/*.scala
You can run the test server from the same directory with this command:
scala EchoServer
Or you can run the ThreeQuestionsServer with this command:
scala ThreeQuestionsServer
From this point on, see the instructions in the previous section starting with what to do about a port-in-use error.
You can delete the old files with this command:
ant clean
The above command will delete the build folder, but not
the releases folder, which is where ant relbin
puts its results. If you want to delete that folder you must do so manually.
From the src/main/scala directory, use this command:
rm *.class net/jimmc/*/*.class
