It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decisions.The development, release, and timing of any features or functionality described for Oracle’s products remains at the sole discretion of Oracle.
Agenda
• Oracle Forms future
• Roadmap
• Oracle Forms and SOA
• Integrating Oracle Forms and services
• Case studies
“I’ve heard Forms is going away, is that true?”
“I am using Forms Client/Server today, what is my path forward?”
“I am going to J2EE, what should I do with my Forms?”
“Is Oracle providing a path to J2EE for Forms developers?”
Common Questions…

Oracle Forms and SOA
SOA Defined
Service Oriented Architecture is an architectural style whose goal is to achieve loose coupling
among interacting software agents. A service is a unit of work done by a service provider to
achieve desired end results for a service consumer.
Dr. Hao He, W3C Web Services Architecture Working Group
Service Oriented Architecture
• New development paradigm
• Think in terms of service• Expose existing functionality
as a service
• New applications composed using services
• Communication with external vendors through services
• BPEL• Standard language for service
orchestration
Benefits of SOA
• Why implement a service-oriented architecture?• Reduced integration expense
• Reuse of resources
• Increased agility
• Reduced maintenance and testing costs
• Reduced business risk
SOA and Oracle Forms
• Integration with external services• SMS, email, file systems, web services
• Integration with Oracle Apps/Siebel/PeopleSoft/SAP• CRM, HR etc.
• Adoption of new technologies• Sharing resources across technologies
• J2EE, client/server, Forms, .Net
• Maintain “legacy” investment
• Reduce risk
• Change your “business logic” as the business dictates

Integrating Oracle Forms and Services
Oracle Forms and Services
• Consume services from Forms• Web services
• BPEL processes
• Forms reacting to external services• File change, email delivery, workflow action
• Expose Forms business logic as services• Refactor PL/SQL
• Execute from other applications
• Orchestrate with BPEL

Case Studies
Case Study - Eurotransplant
• Moved client/server application to the web• Needed secure and remotely accessible application
• Required “self-service” front end• Developed using JDeveloper and ADF
• Required “off-line” application to run in operating theatre with no network access
• Developed a Swing application with JDeveloper and ADF
• Eurotransplant also created JDeveloper extensions to JDeveloper to provide designer functionality.
• Leveraged their Forms/Database skills

“We want to deploy an evolutionary model, not a revolutionary one. In the past, adopting a new
technology frequently meant we had to abandon the old technology. With SOA and Oracle BPEL Process Manager, we are proving that we can service-enable
our existing systems and reuse them in the new architecture.”
Wilfred van der DeijlArchitect, Eurotransplant

“By using SOA, [companies] can evolve their applications at their own speed: Think Big, start Small.
This gives you a step by step approach: adopting SOA, discovering new technologies and tools and finally reuse of existing Forms logic. These are the three most important components of what is known
within Atos Origin as the Forms Roadmap.”
Malcolm SmithPortfolio Manager, Atos Origin
