You can test the SCA Composite Designer and see some possibilities of SCA through the following samples.
This section provides a step-by-step description for creating and testing a sample project.

How to use samples
Register Tuscany for SCA samples
First, you have to install Apache Tuscany to be able to test the sample applications. See the first section on Installing Tuscany to test your SCA applications. You can download it on: (http://incubator.apache.org/tuscany/sca-java-releases.html)
Then, you have to register Tuscany for SCA samples:
- Select Window > Preferences....
- Select SOA Tools > SCA Tools.
- Set the Tuscany directory
- Click on the Ok button.
Creating samples
Different samples are available to test the SCA Composite Designer, they are described in the following sections. The samples projects are automatically created :
- Select File > New > Sample....
- Select SCA > SCA Examples and click Next.
- Select one of the examples and click Next.
- Set the Project name.
- Click Finish. The project is created with the following structure (for the first sample):
Restaurant sample
This sample provides a simple SCA composite named Restaurant. This composite is a composition of five components:
- RestaurantServiceComponent shows the list of proposed menus and computes the bill for the chosen menu.
- MenuServiceComponent provides the menus (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.
The test.Client exercises this interface by calling getMenus and getBill operations. This results in messages passing to the appropriate components in the composite across the local wires (java binding).
