4.1. Understanding the JHeadstart Application Generator Architecture This section describes the high level architecture of the JHeadstart Application Generator (JAG). The JHeadstart Application Generator provides a simple, highly productive means for creating a transaction-based J2EE application using ADF. The high-level development process shown in this diagram follows: 1. Create the business service using ADF Business Components wizards in JDeveloper. This step is independent of JHeadstart. 2. Use the JHeadstart New Application Definition Wizard to create a first-cut of the application definition, the metadata file in XML format required to generate the application. Then, although it is not shown on the diagram, you would refine the metadata using the Application Definition Editor, and customize the generator templates using the JDeveloper code editor. 3. Generate the Model (data bindings), View, and Controller layer code using the JHeadstart Application Generator. This is a highly iterative process, where you refine the metadata and templates based on previous generation results. For an example of a generated page see Figure 2. 4. If the results from the JHeadstart generator do not fully match your functional requirements, you can enhance the generated pages using the JDeveloper ADF tools (visual editors, property inspectors, and drag-and-drop facilities). There are several ways to preserve post-generation changes, as we will discuss later. The Application Definition drives the JHeadstart Application Generator. This is an XML file that defines the overall structure of the application, including: 4 - 2 Using the JHeadstart Addins JHeadstart Developer’s Guide
4.1.1. Input Output • The type of view layer that should be generated (ADF Faces with JSP version 2.0 or 1.2). • The Data Collections that should be displayed and modified. • The layout styles that should be used to display and manipulate the Data Collections. • Relationships between the Data Collections: parent-child or lookup. JHeadstart includes the JHeadstart Application Definition Editor, which is a userfriendly mechanism to edit the Application Definition without having to edit the XML file directly. In addition to the Application Definition, the JAG uses the following inputs: • JHeadstart Generator Templates The JAG parses the Application Definition and generates a Model-View-Controller (MVC) application using the following technologies: • Model: ADF Business Components and ADF Model (data bindings). • View: JSF JSP and ADF Faces. • Controller: JSF. The JAG is capable of generating the following types of output: • Faces Config files for the JSF Controller. • JSF JSP files for each displayed page. • Page Definitons (data bindings) for generated pages. • Resource bundles for internationalization. • SQL scripts for populating the JHeadstart database tables when table-driven features are enabled (dynamic menu, flex items, security, internationalization) The output of the JAG, together with the ADF Business Components, forms the complete web application. Whenever it is required, you can switch on and switch off generation of individual file types. JHeadstart Developer’s Guide Using the JHeadstart Addins 4 - 3
