1. Introducing IBM Rational Software Architect
Prof. dr Angelina Njeguš
Associate Professor

2. Intro to RSA
IBM® Rational® Software Architect - part of the IBM Software Development Platform - is the first major release of Rational products since IBM's acquisition of Rational in February 2003. 
IBM release of the Rational products is built on Eclipse open-source software framework, which provides a unified interface for all the technicals (architects, designers, and developers).
Because Rational Software Architect is built on Eclipse, you can use Rational Software Architect for Java 2 Platform, Enterprise Edition (J2EE Platform) technology.
In addition, using the code-generation features that are a part of Rational Software Architect, you can convert designs and UML diagrams drawn in the Modeling perspective into code.
Finally, the underlying Eclipse platform also provides a robust and feature-rich IDE for developers.

3. What is RSA?
Comprehensive Modeling and Development environment that leverages the Unified Modeling Language (UML) for designing architecture for C++ and Java 2 Enterprise Edition (J2EE) applications and web services

4. Model
A model is a complete description of the system from a particular perspective.

5. Lab 1: Create and run Java application in RSA
Open IBM Rational Software Architect Standard Edition

6. Choose the path
Choose the workspace (folder) where you want your projects to be stored  and click OK.

7. Open desired perspective
Go to Window, click Open Perspective, and then select  Other
Check Show all, select Java, and click OK

8. Create new project
Click File, click New, and then select Project

9. Create Java project
Select Java Project, and click Next

10. Name a project
Choose a name for your project and click Finish. You have now successfully created a java project. 

11. Create Java class
In the Package Explorer, right click on your SampleProject and click on New > Class.
The next Window will appear, and fill with data:
Package: com.sampleproject.common
Name: HelloWorld
Check: public static void main...
Click Finish.

12. Add some code The code of HelloWorld class will appear on the screen
In main method add the next line code:
System.out.println ("Hello World! This is my Java project in RSA");
Click File > Save All

13. Run the code Go to Window > Show View > Console
In the Package Explorer, right click on HelloWorld.java
Click on Run as > Java Application

14. Result
In the Console View, the result of the code will be shown:

15. Lab 2: Create UML project and model
File > New > Project
Check Show all wizards
Expand Modelling folder, select UML Project, and click Next
Choose a name for your project and click Next.
Project name: Bank

16. Create a package Select General > Blank Package
Choose a name for your package  and click Finish.
File name: BankAccount
What is package?
A package is a general purpose mechanism for organising elements into groups.
Packages may be nested within other packages.

17. Create UML package within package
In the Palette view, click on Class > Package
Click on Main editor, and expand the current package element
Choose the name for this package: Customer Account Management

18. Lab 3: Class modelling
Double click on Main in the Customer Account Management package
In the Palette view, click on Class, and name it Account
Right click on Account, and select Add UML > Attribute
Name the attribute: -balance : double, and click Enter.

19. Add operations Right click on class Account, and select Operation
Name the operation: deposit(amount:double):double, and click Enter
Add another operation: withdrawal(amount:double):double

20. Add new classes Add new class: CheckingAccount
Attribute: insufficientFundsFee:double
Operation: withdrawal(amount:double)
Add new class SavingsAccount
Attribute: annualInterestRate:integer
Operations: depositMonthlyInterest(), and withdrawal(amount:double)

21. Add relationships
In the Pallete, under Class, select Generalization

22. Lab 4: UML-to-Java transformation
Create a class diagram:

23. Configure the transformation
To create a new UML-to-Java transformation configuration, select Modeling >Transform > New Configuration in the Main menu.

24. Configure the transformation
In the Name field of the opened New Transformation Configuration wizard, enter the name of the transformation configuration:
Name: MyUMLtoJavaTransform
Click the ellipses (...) button to browse to the UML project Bank
In the list of deployed transformations, open the Java Transformations folder and select the UML-to-Java transformation.
Select the Conceptual protocol type, and click Next.
Note: Choose Conceptual protocol if the intention is to use the source model as a primary engineering artifact in future iterative development. Any changes made to the source model will be propagated to the target project when someone runs the transformation.

25. Specify the source and target elements for the transformation
Select the model BankAccount from the created UML project as a source
Select Create a Target Container

26. Create a new Java project
Create a new Java project named myBankCode, and click Finish 
Select it as a target in the Transformation Configuration wizard, and click Finish

27. Run the transformation configuration
The Java project and transformation configuration files created are visible in the Project Explorer view
The Transformation configuration is opened in the Editor view
Click Run to run the configuration

28. Generated transformation output
The Java code will be generated in the target project 

29. Lab 5: Export the project
File > Export
Expand General, and click on Archive File

30. Export the projects Check the projects that you want to export
Click on Browse to select the path, and name of the archived file
Click Finish

31. Lab 6: Closing the project
File > Save All
File > Close All
Right click on the project in Project Explorer, and click on Close Project.
