Integrating SOA and the Application Development
Framework

• Shaun OBrien
• Principal Product Manager Oracle JDeveloper /
  ADF

Overview

• Oracle Fusion Architecture
• Where do ADF and SOA live?
• How does ADF 11g improve on standard SOA
  integration models?
• Expose ADF Business Components as SDO Web
  Services
• Customizing Human Task Flow activities
• Consuming Web Services utilizing the Web Service
  Datacontrol
• Business Component Eventing

4
Background Oracle Fusion What Is It?

• Oracle Fusion Applications
• Oracles next generation of enterprise
  applications
• Oracle Fusion Middleware
• Integrated standards-based middleware platform
• Oracle Fusion Architecture
• Recommended architecture for your custom
  applications

5
Background What We Wanted Business Drivers

• Cutting Edge UI
• Agility
• System Integration
• Standards
• Scalability, Security, Portability
• Time to market

6
Problem The Development Challenge

• On one side
• JPA, EJB, Ajax, JavaScript, BPEL, SOAP, WSDL,
  RMI, JNDI, JDBC, O/R, HTML, DOM.
• On the other side
• Thousands of developers
• Most dont know these technologies
• Most come from 4GL background
• Expecting a visual and declarative approach
• Dont have time to learn all these new
  technologies
• Need to focus on their specific application needs
• How do you make it easy and approachable?

7
The Solution - Oracle ADF Framework

• Development framework that simplifies development
  of Java EE-based SOA applications
• Abstract developers from technology complexities
• Example - UI Components abstract from Ajax,
  Flash, Javascript, DOM
• Provides end-to-end infrastructure solutions
• O/R Mapping, persistence, caching, controller,
  binding, UI framework, security
• and an easy way to use them
• JDeveloper - Visual editors, Property editors,
  dialogs etc

8
ADF Business Components

• A framework that simplifies developing Java EE
  business services for developers familiar with
  4GL tools, declarative development, and
  relational databases
• Simplify data access
• Uses SQL based data views
• Implement best practices
• Easy customization

9
Business Component Features

• Query by example any field
• Master/Detail coordination
• List of values
• Calculated fields
• Various validations
• Exposing services
• Range fetching
• Transaction control
• Locking mechanism
• State management
• All done declaratively without coding!

Building Business Components
11
ADF Model - Data Binding

• ADF Model
• JSR-227 Data Controls
• Service Oriented Interface
• Abstract implementation from clients
• Loose coupling between services and application
• More Productivity
• Drag and drop data binding
• More Reusability for Services
• Discover and share services

Binding JSF UI to SOA

• The Java EE way
• Write manage bean
• Write JSF page code
• Write EL to connect JSF components to manage bean
• Write more manage bean logic to invoke actions
• The Oracle way
• ADF Binding drag and drop

16
ADF 11g Built-in Data Controls

• ADF Business Components
• Java Class
• EJB
• URL (XML or CSV)
• Place Holder
• Web Service
• BAM
• Add your own

17
ADF and SOA Integration Points

• Expose ADF BC into SCA
• ADF BC Service interface wizard
• Show/Interact human workflow tasks in ADF UI
• Automatically generate ADF forms
• Customize workflow task details through ADF UI
• Invoke a composite from ADF UI
• Use Web service data control based on the
  composite WSDL

18
BAM Data Control

• Expose BAM data
• Drag to the JSF page
• Push to the client with Oracle ADF Active Data
  Services

19
Exposing ADF BC to SCA/SDO

• Expose your DB access layer as services
• Simple wizard based definition
• SOA Adaptor

Create Custom Human Task Page
23
Web Service Data Control

1. Give WSDL
2. Get Data Control
3. Drag and drop to page

24
Business Component Eventing

• Allows publishing of events to the SCA fabric
  from the Business Components tier.
• Can be conditional or not
• Any number of elements can be listeners for the
  event on the ESB.
