发送一个TCP / IP消息AKKA演员

Question

Is it possible to send a message over TCP / IP to an AKKA actor?

For example, write a client like:

mySocket = new Socket("theactor", 75);
os = new DataOutputStream(smtpSocket.getOutputStream());
os.writeBytes("HELLO");    

That could send messages to AKKA actor?

Thanks

Elaborating a little more on Viktor's response, the minimal example would be

import akka.actor._
import ActorDSL._
import java.net.InetSocketAddress

object Server extends App {
  implicit val sys = ActorSystem("telnet")

  actor(new Act with ActorLogging {
    IOManager(context.system) listen new InetSocketAddress(1234)
    become {
      case IO.NewClient(server) ⇒
        server.accept()
      case IO.Read(handle, bytes) ⇒
        log.info("got {} from {}", bytes.decodeString("utf-8"), handle)
    }
  })
}

Then in a different shell start telnet localhost 1234 and start typing, you'll see one actor log message per line.

Yes, and no. You'll have to use Akka IO module or Akka Camel module (with netty or mina component):

If you are trying to send a message across a remote actor using IP, Why don't you try the Akka Remote Actor system? "Read it here"
