Question

I wish to use the Akka actor modules.
I am using Eclipse in Kubuntu.
I downloaded the .zip archive from the akka website, went to:

Project->Properties->Java Build Path->Libraries->Add External Jar

and added all jars that came with the zip.

In my code, I do:

import akka.actor.Actor;
import akka.event.EventHandler;

class MyActor extends Actor{




}

and I get a straight error in line:

class myActor extends Actor{

Error is:

The type Actor cannot be the superclass of MyActor; a superclass must be a class

But isn’t Actor supposed to be a class? At least that is what all the tutorials say.

Answer 1

Try with akka.actor.UntypedActor. From the reference documentation:

Actor in Java are implemented by extending the UntypedActor class and
implementing the onReceive method. This method takes the message as a
parameter.

Here’s an example: https://github.com/alexaverbuch/akka_chat_java/blob/master/src/main/java/chat/actors/Session.java
