I cant get my head around this one here I am a beginner to Scala just few weeks old and have tried but failed I have read and tried about Actors, Futures,...etc didnt work for me
Could you supply a code of a server client example (or at least the server side) Suppose to open connection using a socket that receives a string (i.e. file path) from several clients and process each one in a thread
import java.net.{Socket, ServerSocket}
import java.util.concurrent.{Executors, ExecutorService}
import java.util.Date
import java.io._
import scala.io._
import java.nio._
import java.util._
import scala.util.control.Breaks
import java.security.MessageDigest
import java.security.DigestInputStream
import scala.util.Sorting
class NetworkService(port: Int, poolSize: Int) extends Runnable {
val serverSocket = new ServerSocket(port)
val pool: ExecutorService = Executors.newFixedThreadPool(poolSize)
def run() {
try {
var i = 0
while (true) {
// This will block until a connection comes in.
val socket = serverSocket.accept()
val in = new BufferedReader(new InputStreamReader(socket.getInputStream)).readLine
/*var f = new FileSplit(in) //FileSplit is another class that i would like each
// client's sent string to be passed as an instance of
f.move*/
pool.execute(new Handler(socket))
}
} finally {
pool.shutdown()
}
}
}
class Handler(socket: Socket) extends Runnable {
def message = (Thread.currentThread.getName() + "\n").getBytes
def run() {
socket.getOutputStream.write(message)
socket.getOutputStream.close()
}
}
object MyServer {
def main(args: Array[String]) {
(new NetworkService(2030, 2)).run
}
}
