Development log of TicToe HTML5

Now it is time to get a basic (empty) server up and running.


Marauroa is configured using a server.ini file. It tells the framework, how it can access its database and contains further information about the game. For now, just copy and paste the following code and save it as server.ini in your project root folder.

# Configure database using the serverless H2 engine

# TCP port for traditional clients

# Web port

# The length of the server game loop in milliseconds

# Name of our game

HTML5 just use https for secure communications and that is handled by the webserver. But for traditional clients, Marauroa has to do the encryption. Therefore we need to generate a key pair with the command: It will ask for the key length and then output 3 lines that we append to the server.ini.

# Encryption key

Important: Do not use these example keys but create your own pair.

Starting the server

Make sure that marauroa.jar, and its dependencies are on the classpath. Then execute the class

If all goes well, you will be greeted by some status message. The last one will be:

INFO  [main      ] marauroad                (123 ) - marauroa is up and running... (startup time: 3.1 s)

Testing client/server communication

To test the setup, we open a web browser at http://localhost:8080/index.html.

This will just result in a green screen, but we can manually connect to the server by using the Firebug console. There is an input field at the bottom, that allows you to call any defined method and to inspect any object.

First of all, we need to connect to the server. Type this command and wait for the message "connected" in the console log:

  • marauroa.clientFramework.connect(null, null);
    • connected

While it is possible to execute more methods here, this is not useful because we have not implemented any server code, yet.
