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
Background: Oracle Fusion – What Is It?
• Oracle Fusion Applications
• Oracle’s next generation of enterprise applications
• Oracle Fusion Middleware
• Integrated standards-based middleware platform
• Oracle Fusion Architecture
• Recommended architecture for your custom applications
Background: What We Wanted – Business Drivers
•

•
•
•
Cutting Edge UI
Agility
System Integration
Standards
Scalability, Security, Portability
Time to market
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 don’t know these technologies
Most come from 4GL background
Expecting a visual and declarative approach
Don’t have time to learn all these new technologies
Need to focus on their specific application needs
• How do you make it easy and approachable?
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…
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
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
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

Add your own
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
BAM Data Control
• Expose BAM data
• Drag to the JSF page
• Push to the client with
Oracle ADF Active
Data Services
Exposing ADF BC to SCA/SDO
• Expose your DB access
layer as services
• Simple wizard based
definition
• SOA Adaptor

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