Setup Application

The AWA.Setup package implements a simple setup application that allows to configure the database, the Google and Facebook application identifiers and some other configuration parameters. It is intended to help in the installation process of any AWA-based application.

It defines a specific web application that is installed in the web container for the duration of the setup. The setup application takes control over all the web requests during the lifetime of the installation. As soon as the installation is finished, the normal application is configured and installed in the web container and the user is automatically redirected to it.


To be able to use the setup application, you will need to add the following line in your GNAT project file:

with "awa_setup";

The setup application can be integrated as an AWA command by instantiating the AWA.Commands.Setup generic package. To integrate the setup command, you will do:

with AWA.Commands.Start;
with AWA.Commands.Setup;
package Start_Command is new AWA.Commands.Start (Server_Commands);
package Setup_Command is new AWA.Commands.Setup (Start_Command);

Setup Procedure Instantiation

The setup process is managed by the Configure generic procedure. The procedure must be instantiated with the application class type and the application initialize procedure.

 procedure Setup is
    new AWA.Setup.Applications.Configure (MyApp.Application'Class,

Setup Operation

The Setup instantiated operation must then be called with the web container. The web container is started first and the Setup procedure gets as parameter the web container, the application instance to configure, the application name and the application context path.

Setup (WS, App, "atlas", MyApp.CONTEXT_PATH)

The operation will install the setup application to handle the setup actions. Through the setup actions, the installer will be able to:

  • Configure the database (MySQL or SQLite),
  • Configure the Google+ and Facebook OAuth authentication keys,
  • Configure the application name,
  • Configure the mail parameters to be able to send email.

After the setup and configure is finished, the file .initialized is created in the application directory to indicate the application is configured. The next time the Setup operation is called, the installation process will be skipped.

To run again the installation, remove manually the .initialized file.
