Integrating SOA and the Application Development FrameworkShaun O’BrienPrincipal 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• 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
ADF 11g Built-in Data Controls
• ADF Business Components• Java Class• EJB• URL (XML or CSV)• Place Holder• Web Service• BAM• 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 WSDL2. Get Data Control3. 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.
