-------------------------------------------------------------------------------- 1 | Akka Remote Example in Java 2 | ========================= 3 | 4 | ## Introduction 5 | This project was made while testing the Akka Remoting features. 6 | It contains three modules; a Client, a Server and a LoggerEnvironment. The two types of Akka Remoting are tested; Creation and Lookup. 7 | 8 | ##### Client 9 | The client uses remote lookup to get an `ActorSelection` of a Remote Actor (running on the Server.) and sends a message to it. 10 | 11 | ##### Server 12 | The server creates a `CalculatorActor` and handles incoming messages. 13 | The server also creates a `LoggingActor` which is (remotely) deployed on the `LoggerEnvironment`. 14 | 15 | ##### LoggerEnvironment 16 | Essentially nothing more than a container. The server will create an actor on this environment. 17 | 18 | ## How to run 19 | You can run the program like every ordinary Java main program. Make sure you have `mvn clean install`ed the project before to get the Akka dependency. 20 | It's important to run the projects in the following order: 21 | 22 | 1. LoggerEnvironment 23 | 2. Server 24 | 3.
