Introducing IBM Rational Software Architect Prof. dr Angelina Njeguš Full Professor

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 (J 2 EE 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.

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 (J 2 EE) applications and web services

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

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

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

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

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

Create Java project • Select Java Project, and click Next

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

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

Add some code • The code of Hello. World 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

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

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

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

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

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

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.

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

Add new classes • Add new class: Checking. Account – Attribute: insufficient. Funds. Fee: double – Operation: withdrawal(amount: double) • Add new class Savings. Account – Attribute: annual. Interest. Rate: integer – Operations: deposit. Monthly. Interest(), and withdrawal(amount: double)

Add relationships • In the Pallete, under Class, select Generalization

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

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

Configure the transformation • In the Name field of the opened New Transformation Configuration wizard, enter the name of the transformation configuration: – Name: My. UMLto. Java. Transform • 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.

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

Create a new Java project • Create a new Java project named my. Bank. Code, and click Finish • Select it as a target in the Transformation Configuration wizard, and click Finish

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
