This is a project demonstrating the principles of socket programming in Kotlin.

Communication Networks, 5th semester of Computer Science Dept. @ Aristotle University of Thessaloniki

This repository essentially contains two programs, one for the mail server and one for the mail client (application).

The first one can be found in email-server/, which is a basic threaded Socket Server waiting for incoming requests. The other one can be found in email-client/, which is a TornadoFX application for the client. TornadoFX is a JavaFX framework for Kotlin which supports the Model-View-Controller (MVC) pattern.

The package that's connecting the two programs can be found in email-common/, which contains all the common entities and the request/response types that are available to both the client and the server so that they can communicate efficiently.

The JDK version that was used for development is 11.0.1+13-LTS so in case any issues with TornadoFX show up, you can try downloading that specific version to see if there's been a breaking change. The app should run on both Windows and Linux.

You can compile this multi-project with gradle shadowJar, which will build the executable jars in email-client/build/libs/ and email-server/build/libs/ for the client and the server respectively. (This makes everything so much easier, doesn't it?!)
