SCA/SCA Component/SCA First Steps With Composite Designer

The objective of this tutorial is to show how to develop a simple SCA application using the STP/SCA Composite Designer.

You can download a pdf version of this tutorial: "First Steps with the SCA Composite Designer".

The tutorial illustrates how to:

  • Install the STP/SCA plugins and Apache Tuscany
  • Define an SCA assembly with the SCA Composite Designer
  • Refine properties in an SCA assembly
  • Define an SCA assembly with different implementation technologies
  • Define an RMI binding
  • Run and test SCA assemblies with Tuscany


Prerequisities

In order to be able to test the sample SCA application, you need to :

  • install Apache Tuscany on your machine,
  • set up Eclipse for Tuscany.

The SCA Restaurant Application

The following figure shows the SCA assembly of the application that you will create. RestaurantOverview.png

This composite, named restaurant, is a composition of five components:

RestaurantServiceComponent
Allows you to see the Menus proposed by the restaurant.
It allows also to compute the bill for a particular menu.
MenuServiceComponent
Provides different menus. A Menu is defined by a description and the price without taxes.
BillServiceComponent
Computes the price of a menu with the different taxes.
VATServiceComponent
Computes the VAT (Value Added Tax).
TipServiceComponent
Computes the tip.
