Steven Davelaar

Oracle, Technical Director

Agenda

• What is JHeadstart

• Seeing is believing: demo!

• Generated ADF design patterns

• JHeadstart reusable components

• JHeadstart generator templates

• (JHeadstart Forms2ADF Generator)

4

What is JHeadstart?

• JDeveloper extension for template-based automation of

ADF development tasks

– Development Toolkit on top of ADF

– Builds on ADF Runtime architecture

– Fully integrates with ADF Design Time

• Takes declarative development to the next level

– Generates complete ADF applications

– Like the Designer Forms Generator generates Forms apps,

JHeadstart generates ADF apps

• Transforms Oracle Forms into ADF applications

5

JHeadstart – Main Components

• JHeadstart Application Generator (JAG)

– Generates best-practice web application

• JHeadstart Utilities

– Automate other ADF development tasks

– Perform quality checks

• JHeadstart Runtime

– Reusable components to implement complex functionality

– Auto-implements host of best practices

• JHeadstart Forms2ADF Generator

– Create fully-functional ADF app based on forms definitions

• JHeadstart Developer’s Guide

6

JHeadstart Application Generator (JAG)

• Generates ADF Faces pages and fragments

• Generates (un)bounded task flows

• Generates page definitions (data bindings)

• Does NOT generate any Java code, only XML!

• JAG is driven by

– XML-based Application Definition file, created and edited

through GUI Wizard (JDeveloper add-in)

– Velocity Generator Templates

• Generated output is 100% customizable

Enhanced UI Shell with Dynamic Tabs

22

JHeadstart Uses Best Practice ADF Design Patterns

• “One-page” application (UIShell)

– Generated bounded task flows use page fragments and can be

embedded as ADF region in page

– One page with dynamic region driven by application menu

• Generated task flows are highly reusable

– Use with traditional menu structure

– Use with dynamic tabs

– Use in handbuilt drag-and-drop pages

– Use as child within another region

– Use with human workflow task list

– Use as popup / list of values

– Use as WebCenter portlet

– Add at runtime using WebCenter Composer

23

JHeadstart Uses Best Practice ADF Design Patterns

• Generated task flows are highly configurable

– Configure to start in create mode (new row)

– Configure to show one specific row (deeplinking)

– Configure to go to summary or detail page

– Configure to hide action buttons (Save, Cancel, Nav. Buttons)

– Configure to hide search region

– Configure to show in read-only mode

• Generates layout best practices

– Easy switching between stretching and non-stretching layouts

• Region interaction design patterns are auto-

implemented

Reusable Application

Components

27

Reusable Application Components

• Fine-grained permission-based authorization,

seamlessly integrated with ADF Security

• Dynamic menu structure

• Flex Items: Adding new items at runtime

• Runtime customization of standard items

– Show/hide

– Make mandatory

• Runtime translation/modification of page text

28

Reusable Application Components - Packaging

• DDL script to Create Table Structure

• Predefined Business Components with application

module that is nested within own app module

• JHeadstart Application Definitions generated, that can

be used to generate admin screens

• SQL scripts are generated and executed to populate

the database tables

– Roles, Permissions (Group Access/Action), Grants

– Module and menu items

– Translations

– Flex Region Definitions

Recommended Approach to Customizing Generated

Output

• Use the visual design time tools in JDeveloper to

make any modifications you like

– Drag and drop from control palette

– Structure pane

– Property inspector

– ..

• Run the modified page and verify it works as

expected

• Move the custom page code to a custom template to

preserve the modifications upon regeneration

• (or switch off page generation flag and skip last step)

37

JHeadstart Generator Templates

– The content of generated pages is completely

driven by Velocity generator templates

– The templates are categorized in groups

• Page, pageComponent, button, item

(table/form/search), search, misc, etc.

– Which template is used for which page “snippet” is

handled by defaultTemplateBindings.jtp file.

– You can customize anything that is generated

onto a page by creating a custom template

What about PL/SQL Logic?

• Custom PL/SQL Logic not automatically migrated to Java

• JHeadstart prefers sound multi-tier target architecture(ADF MVC) above automated PL/SQL migration– Analyze the logic

– Determine in which tier(s) it should be implemented

– Determine how to implement it

• Application Definition Editor shows all form, block and item triggers and all program units– Good overview of all custom PL/SQL logic

– Ability to move logic to database, to ADF BC or to JSF managed beans

JHeadstart Superior Productivity – In Many Ways

• Saves you months to figure out ADF best practices

• Saves you months with ready-to-use reusable

components

• Maximizes reuse

– JAG is actually RTG: Reusable Taskflows Generator

• Facilitates agile development

– Start with generating functional prototypes that evolve into

working system

• Eases upgrade to new JDeveloper releases

– Technology-agnostic metadata layer!
