THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Ready, Set, Go - Getting started with Tuscany
This article will show you how to download a Tuscany distribution, add the distribution as a user library in Eclipse, create the Store sample as a Java project, and then run the Store and use it from a web browser.
| Info |
|---|
Although this guide show some images based on the Java SCA 1.3.1 2 release, you should be able to use latest Java SCA release while going to the necessary steps for this guide. |
...
The first thing you do is to create a file system folder on you disk into which you will download the TUSCANY distribution.

And then you can Checkout to complete your order.
Explore the Samples from the Tuscany Distribution
The sample folder of the Tuscany distribution provides a rich set of samples ready for you to explore.
In Eclipse create a New Java Project, specify the project name, select Create project from
existing source, and specify the folder that contains the sample source.
Use Next to get to the next page in the New Java Project dialog. There go to the Libraries tab, use
the Add Library... pushbutton to add the JUnit library and the user library TUSCANY.
Finish the New Java Project dialog. You now have the sample project available in the Eclipse workbench.
For the calculator sample that we've chosen go to its CalculatorClient class and select Run As ->
Java Application. You will see the following output in the console.
Congratulations, you have created an accessible, flexible, reusable Store application using Tuscany SCA technolog.
