What is Rose Java Edition?

• Automatic generation of Java Source code
• JDK 1.0.2 and 1.1x
• Reverse engineering of Java source and byte code
• Round trip engineering capability that
  synchronizes models and generated Java source
  across multiple iterations
• changes made to a model are carried through to
  code during code generation
• changes made to code are carried back to the
  model during reverse engineering

About Java Base Classes

• Rose automatically places a set of Java Base
  Classes

Forward Engineering Process

• Loading Java base classes into a Rose model
• Defining classes, components, and other model
  elements
• Assigning classes to components
• Checking syntax
• View and complete the generated Java source

9
Create a Logical Package and Classes

• 1. In the logical view of your new model, create
  a logical package called Myapps.
• 2. Create a logical class in the package and call
  the class WelcomeApp.

Create a Component Package and Component(1)

• 1. In the component view, create a component
  package called MyApps.
• 2. Create a component in the package and call the
  component WelcomeApp.

13
Create a Component Package and Component(2)

• 3. Double-click on the component in the Browser
  or in the diagram to open its specification and
  verify that the Language field is set to Java.

14
Assign the Class to the Component

• 1. In the Browser window, drag the WelcomeApp
  class to the WelcomeApp component to assign the
  class to the component.

2. Double-click on the WelcomeApp class in the
Browser or in the class diagram. 3. Select the
Components tab in the WelcomApp class
specification. Note that the WelcomeApp component
is checked, denoting that the class is assigned
to it.
15
View the Component Specification

• 1. Double-click on the WelcomeApp component in
  the Browser or in the component diagram.
• 2. Select the Realizes tab in the component
  specification. Note that the WelcomeApp class is
  checked, denoting the components class
  assignment.(the Realizes relationship in Rose
  corresponds to the Implements relationship in
  Java)

16
Add a New Method

• 1. Select the WelcomeApp class in the Browser or
  in the class diagram.
• 2. Right-click on the WelcomeApp class and select
  New Operation from the Menu

3. Double-click on the WelcomeApp class to
display its Class Specification 4. Select the
Operations tab to view the operation you added
17
Edit the New Method(1)

• 1. Double-click on the operation to edit its
  Operation Specification
• On the General tab, change the operation Name to
  main and the Return class to Void

18
Edit the New Method(2)

• On the Java tab, double-click on the Static
  property and set it to True.

19
Edit the New Method(3)

• On the Detail tab, specify a parameter as an
  array of string.
• Click OK to save your changes to the operation
  specification.

20
Edit the New Method(4)

• 2. Notice that the main operation now appears
  both in the Operation Specification and in the
  Browser.
• 3. Close the specification and save your model so
  you dont lose any of your work to this point

21
Set the Project Directory Property(1)

• 1. Point to Model Properties on the Tools menu
  and select Edit.

22
Set the Project Directory Property(2)

• 2. When the WelcomeApp class specification is
  displayed, go to the Java tab and click Edit Set
  to access the property editor.

23
Set the Project Directory Property(3)

• 3. Use the Type drop-down box to find and select
  the Project type.(Remember, Directory is a
  Project property, so we want to go the property
  set that applies to project.)

24
Set the Project Directory Property(4)
4. Double-click on the Directory property to
allow editing of its current value, which is, as
you can see, AUTO GENERATE.

• 5. Replace AUTOGENERATE with a directory of your
  choice. This example uses C\MyWork\MyJava\.

25
Generate Java(1)

• 1. Select the WelcomeApp component or class in
  the Browser or in a diagram.
• 2. On the Tools menu, point to Java and click
  Generate Java.

26
Generate Java(2)

• 3. Click the Rose Log window for information on
  errors or successful Java generation.
• 4. Close the Log window.

27
View Java Source(1)

• 1. With the WelcomeApp component or class still
  selected, point to Java on the Tools menu and
  click Browse Java Source.

28
View Java Source(2)

• You generated .java file is automatically opened
  and looks like this
• 2. Optionally, check Window Explore to find the
  new directory you created and the generated .java
  file it contains.

29
Edit Java Source

• 1. Add the command to print the Welcome to
  Rational Software! Message(or any message you
  prefer).

Compile and Run 1. Use the Javac compiler to
compile your completed .java file. 2. Run the
application and see what you get.
