EXECUTIVE OVERVIEW Changing markets, increasing competitive pressures, and evolving customer needs are placing pressure on IT to deliver greater flexibility and speed. In response to these challenges, leading companies are adopting service-oriented architecture (SOA) as a means of delivering on these requirements by overcoming the complexity of their application and IT environments. SOA represents a fundamental shift in the way new applications are designed, developed, and integrated with legacy business applications, and facilitates the development of enterprise applications as modular business services that can be easily integrated and reused. In order to rapidly build portable applications to SOA, you need an integrated services environment (ISE) and a service-oriented application framework. Oracle JDeveloper, Oracle Application Development Framework (Oracle ADF), and Oracle TopLink are development components of Oracle SOA Suite that together form a comprehensive ISE to develop, compose, and orchestrate services into business processes that can be deployed, registered, and consumed from several types of user interfaces, including desktop clients, browsers, and mobile and telnet devices. Oracle SOA Suite is a standards-based best-of-breed suite that enables you to build service- oriented applications and deploy them to your choice of middleware platform. It consists of (i) an integrated service environment (ISE) to develop services; (ii) a multi-protocol Enterprise Service Bus (ESB) to integrate applications; (iii) a services registry for discovering and managing the lifecycle of services; (iv) a BPEL-based orchestration engine to tie services into business processes; (v) a business rules engine to enable business policies to be captured and automated; (vi) a Web Services management and security solution to enforce authentication and authorization policies on services and to monitor services and processes for compliance to SLAs; (vii) a Business Activity Monitoring (BAM) solution to gain real- time visibility into business entities and their interactions, and a means to enable automated actions to be performed; and (viii) an enterprise portal for employees, customers, and partners to access content, access relevance performance metrics, collaborate and take actions via interaction with business processes. Oracle SOA Suite can help you achieve greater organizational flexibility better than any other solution in the market. It can reduce your costs and middleware complexity better than any other solution. Finally, it can help you achieve the best total value of opportunity.

INTRODUCTION Today, every organization is faced with the need to predict changes in the global business environment, to rapidly respond to competitors, and to best exploit organizational assets to prepare for growth. Your enterprise application infrastructure can either help you meet these business imperatives or it can impede your ability to change. To help you, your infrastructure must: • Improve your ability to predict and respond to change • Enhance organizational productivity • Simplify your information technology environment • Leverage existing investments In order to deliver on these requirements and overcome the complexity of their IT environments, leading companies are adopting service-oriented architecture (SOA). SOA represents a fundamental shift in the way new applications are designed, developed, and integrated with legacy business applications, and facilitates the development of enterprise applications as modular business services that can be easily integrated and reused. As SOA is evolving from being a best practice for the few to being the common practice for the mainstream, new ISEs are emerging. An ISE is a suite of integrated development tools and technologies for building SOA and composite applications. ISEs are producer platforms for creating services. Oracle JDeveloper is an ISE that enables developers to model, create, discover, assemble, orchestrate, test, deploy, and maintain composite applications based on services. JDeveloper supports SOA principles and XML Web Services standards, as well as traditional Java, J2EE, and PL/SQL component and modular code mechanisms. Oracle ADF is an SOA framework that automates and manages business and data services and provides a standard data- and service-binding layer based on JSR 227 that can be used with process flows, page flows, and service invocations. Oracle ADF also implements SOA design practices, and makes user interfaces as loosely coupled as services themselves. Oracle TopLink is a data services framework that allows access to relational and XML data. Oracle TopLink and Oracle ADF frameworks simplify creation of business and data services that can be invoked from rich Web interfaces of service-oriented applications. Oracle JDeveloper, Oracle ADF, and Oracle TopLink together provide a comprehensive integrated services environment and framework that allows developers to use the Oracle Fusion Architecture to build model-driven applications, services, and business processes, which can then be deployed and registered into Oracle Fusion Middleware or other middleware platforms. Oracle SOA Suite is a standards-based best –of--breed suite that enables you to build service- oriented application and deploy them to your choice of middleware platform. It consists of: 1. An integrated service environment (ISE) to develop services 2.

A Business Activity Monitoring (BAM) solution to gain real-time visibility into business entities and their interactions, and a means to enable automated actions to be performed 8. An enterprise portal for employees, customers and partners to access content, access relevance performance metrics, collaborate and take actions via interaction with business processes. This paper outlines how Oracle JDeveloper, Oracle ADF, and Oracle TopLink provide an ISE for building service-oriented applications.

BUSINESS NEEDS SOA isn’t just hype: it is quickly becoming the de facto software architecture for many IT organizations. Industry pundits say that by 2008, SOA will be the prevailing software engineering practice in the enterprise—ending the 40-year reign of the monolithic software architecture. Organizations plan to adopt (or have already adopted) SOA as a preferred architecture to meet the following needs:

Leader Associated Wholesales Inc Simplify your information technology environment Sept - 2005. Developing SOA applications typically involves a wide variety of tools that cater to different aspects of service-oriented development. The use of multiple tools results in fragmentation of standard development approaches, continuous steep learning curve for getting started with different tools, and increased total cost of ownership for the development environment. You can simplify the development environment by having a single cohesive ISE. Oracle JDeveloper with its standards-based and comprehensive feature set provides complete lifecycle development facilities for service-oriented applications including modeling, generation, develop, compile, debug, run, deploy, and register from a single unified ISE.

Leverage existing investments Organizations can leverage existing investments by being modular, open, and extensible to allow you to adopt them in a heterogeneous environment without needing to remove or replace your existing systems. Organizations use a wide variety of technologies (EJB, TopLink, Java classes, Web Services, XML, Struts, Java Server Faces (JSF), and other open source frameworks) to build applications and services. Organizations also frequently employ a diverse set of developers: application architects, business developers, core developers, and so on. Organizations want both to protect their investment in earlier and current technologies and to reuse wide range of developer skills at their disposal. Oracle JDeveloper, Oracle ADF and Oracle TopLink support the latest Java, XML and Web Services standards to provide a single cohesive development environment that is extensible and supports heterogeneous environment.

ORACLE JDEVELOPER OVERVIEW Oracle JDeveloper is the industry’s most comprehensive and cohesive integrated services environment for developing services, business process, and applications using the latest industry standards for Java, J2EE, SQL, XML, and Web Services. Oracle JDeveloper supports the complete development life cycle for service-oriented applications, with integrated features for modeling, coding, debugging, testing, profiling, tuning, deploying, and registering services, applications, and business processes. Enterprise Java Beans (EJB) 3.0 and Java Server Faces (JSF) are two of the cornerstone technologies for the next generation of enterprise Java. EJB 3.0 provides simple code Oracle SOA Suite œ JDeveloper, Develop Flexible, Adaptable Service 5 ADF, and TopLink Oriented Applications

annotations and standard persistence model to build backend business logic. JSF provides a loosely coupled and reusable component model where the same components can be rendered on multiple types of devices (browser, telnet, mobile). JSF also provides rich eventing model, and navigation model that results in building sophisticated user interfaces. These two technologies simplify the complexity of J2EE development, and serve as the building blocks both for business services and rich SOA Web interfaces. Oracle JDeveloper facilitates development of backend applications and services using Enterprise Java Beans (EJB) 3.0, and it facilitates development of highly sophisticated user interfaces using the JSF reusable component model that can be rendered on different types of devices. Oracle ADF provides a 100% industry standards–based SOA development framework built —[Oracle ADF] makes JDeveloper more on the Model-View-Controller design pattern to dramatically improve developer productivity. attractive to people who are mainstream It combines visual and declarative development capabilities with prebuilt runtime libraries developers.

USE CASES Service-oriented application development essentially consists of following tasks: • Creating services • Orchestrating services • Binding user interfaces to services Oracle JDeveloper, Oracle ADF, and Oracle TopLink are built and designed to optimize these development tasks and to facilitate service-oriented application development.

Creating Services Oracle JDeveloper provides a comprehensive design time to create Web Services either in top-down or bottom-up fashion. Developers can expose and publish a wide variety of existing Java applications, J2EE components such as EJB, Java Message Service (JMS) destinations (Queues or Topics), and PL/SQL packages as Web Services from the bottomup. Developers can also generate a service from an existing WSDL that models a business process and use the XML schema editor (Figure 1) and the WSDL editor (Figure 2) to 6

productively develop top-down assembly style of Web Services. JDeveloper also provides adapters based on Java Connector Architecture (JCA) that facilitate access to messages in the file system using file transfer protocol, that send and receive messages from Oracle Advance Queuing or standard JMS based message systems, and expose that business functionality in Oracle E-Business Suite as standard Web Services.

Oracle JDeveloper doesn’t just stop at modeling business processes — it also provides the design time that facilitates orchestrating legacy systems, business applications, and messaging systems using Web Services Invocation Framework (WSIF) to maximize business applications connectivity. 8

Binding User Interfaces to Services SOA requires not only a standard way to create and expose loosely coupled services, but also a means to bind the data from these services into several types of user interfaces, including desktop clients, browsers, and mobile and telnet devices. Oracle is working with the Java community to deliver a new specification (JSR- 227) within the Java Community Process (JCP) that defines a standard dynamic framework optimized for an SOA. Oracle ADF is an implementation of JSR-227 that specifies a declarative framework which greatly improves developer productivity when binding a user interface to services. It defines a way to abstract bindings between business tier and view/controller layers. Abstraction to backend services such as BPEL processes, EJB applications, Web Services, the Java object model, standard Java Classes is done using two artifacts: data controls and data bindings. Data bindings serve as lightweight objects that can be used to bind the data coming from backend systems and services onto the UI components of the view layer. Data controls serve as a service-oriented interface with information about data collections and service methods. Data controls and Data bindings together provide a loosely coupled and reusable architecture where different types of user interfaces can talk to heterogeneous backend services (See Figure 4).

Figure 4: Oracle ADF

Oracle JDeveloper comes nicely integrated with the Oracle ADF design time and runtime to simplify application and services development. Developers can simply drag and drop a component or service into the Data Control Palette of JDeveloper (Figure 5) to abstract it out as a loosely coupled service that can be used from any type of user interface.

Figure 5: Data Control Palette

Developers are also able to create JSF page flow diagrams, which allows visualizing the navigation between Web pages and individual JSF pages with the rich set of ADF Faces components that come with JDeveloper using simple operations. These JSF pages can be easily wired to backend business logic or services using data and methods exposed via the Data Control Palette with simple drag and drop operations and property editors.

Oracle SOA Suite œ JDeveloper, Develop Flexible, Adaptable Service 13 ADF, and TopLink Oriented Applications

Over the last two years or so AWI have moved from an essentially mainframe-based IT model to embrace a more service-oriented approach using a combination of web- and Swing- based applications that are underpinned by a central order processing system built using EJB 2.1 against a backend database.

The web-based systems have all been developed using JSP and Struts, with the Oracle ADF framework supplying the model and business service layer. The Swing-based applications also utilize Oracle ADF and have been developed for offline applications that support the large number of retail and distribution tradeshows that AWI are involved in each year.

AWI evaluated a number of possible solutions for these projects and selected Oracle ADF because of its completeness and use of recognized and proven design patterns. Les Morton, Project Director, comments "AWI was a mainframe-based shop. We decided to go down the track of adopting a service oriented architecture and chose the Oracle ADF framework because it implemented the best practices and design patterns for this type of development, so I didn’t have to worry about determining whether we were doing it the right way. "

CONCLUSION Changing markets, increasing competitive pressures, and evolving customer needs are placing greater pressure on IT to deliver greater flexibility and speed. Organizations are looking at enterprise application infrastructure to (i) improve their ability to predict and respond to change(ii) enhance organizational productivity iii) simplify your information technology environment and(iv) leverage existing investments. In order to deliver on these requirements and overcome the complexity of their IT environments, leading companies are adopting service-oriented architecture (SOA). SOA represents a fundamental shift in the way new applications are designed, developed, and integrated with legacy business applications, and facilitates the development of enterprise applications as modular business services that can be easily integrated and reused.
