Book Description

We are moving towards a standards-based Service-Oriented Architecture (SOA), where IT infrastructure is continuously adapted to keep up with the pace of business change. Oracle is at the forefront of this vision, with the Oracle SOA Suite providing the most comprehensive, proven, and integrated tool kit for building SOA based applications.

Developers and Architects using the Oracle SOA Suite, whether working on integration projects, building composite applications, or specializing in implementations of Oracle Applications, need a hands-on guide on how best to harness and apply this technology.

This book will guide you on using and applying the Oracle SOA Suite to solve real-world problems, enabling you to quickly learn and master the technology and its applications.

The initial section of the book is aimed at providing you with a detailed hands-on tutorial to each of the core components that make up the Oracle SOA Suite; namely the Oracle Service Bus, BPEL Process Manager, Human Workflow, Business Rules, and Business Activity Monitoring. Once you are familiar with the various pieces of the SOA Suite and what they do, the next question will typically be: "What is the best way to combine / use all of these different components to implement a real-world SOA solution?"

Answering this question is the goal of the next section. Using a working example of an online auction site (oBay), it leads you through key SOA design considerations in implementing a robust solution that is designed for change. Though the examples in the book are based on Oracle SOA Suite 10.1.3.4 the book will still be extremely useful for anyone using 11g.

The final section addresses non-functional considerations and covers the packaging, deployment, and testing of SOA applications; it then details how to use Web Service Manager to secure and administer SOA applications.

Chapter 5: Using BPEL to Build Composite Services and Business Processes

What You Will Learn

 

  • Learn to use key technology adapters to service-enable existing systems
  • Build implementation-agnostic services using the Oracle Service Bus
  • Assemble services to build composite services and long-running business process using BPEL
  • Initiate and discover how business rules can be used to externalize "decision points" in a BPEL process
  • Incorporate Human Workflow into your processes and use Business Rules to provide greater agility
  • Design XML schemas and service contracts for improved agility, reuse, and interoperability
  • Examine different approaches either from scratch or by re-using existing logic for building new business services
  • Observe the protocols available in addition to SOAP over HTTP for invoking Web Services and the advantages they provide
  • Create, deploy, and run test cases that automate the testing of composite applications
  • Secure and administer SOA applications using Web Service Manager
  • Architect, design, and implement your overall SOA Solution
  • Design your Web Service contracts for interoperability and maintainability

Section 1 – Getting Started

Chapter 1: Introduction to Oracle SOA Suite: An initial introduction to the Oracle SOA Suite and its various components.

Chapter 2: Writing your first service: A hands-on introduction to the core components of the Oracle SOA Suite, namely the Oracle BPEL Process Manager and the Oracle Service Bus.

Chapter 3: Service-enabling existing systems: Looks at a number of key technology adapters and how we can use them to service-enable existing systems.

Chapter 4: Loosely coupling services: Describes how we can use the Oracle Service Bus to build services that are implementation-agnostic.

Chapter 5: Building composite services and business processes: Covers how to use BPEL to assemble services to build composite services and long-running business process.

Chapter 6: Adding in human workflow: This chapter looks at how human tasks can be managed through workflow activities embedded within a BPEL process.

Chapter 7: Using business rules to define decision points: This chapter introduces business rules and how we can use them to externalize "decision points" in a BPEL process.

Chapter 8: Building real-time dashboards: This chapter looks at how Business Activity Monitoring (BAM) can be used to give business users a real-time view into how business processes are performing.

Section 2 – Putting it all together

Chapter 9: oBay introduction: Provides a blueprint for our SOA architecture, highlighting some of the key design considerations and describing how they fit our architecture for oBay.

Chapter 10: Designing the service contract: Gives guidance on how to design XML schemas and service contracts for improved agility, reuse, and interoperability.

Chapter 11: Building business services: Examines different approaches for building new business services either from scratch or by re-using existing logic.

Chapter 12: Building validation into services: Examines how we can implement validation within a service using XSD validation, Schematron, and Business Rules.

Chapter 13: Error handling: This chapter examines strategies for handling system and business errors, with detailed coverage of the BPEL Fault Management Framework.

Chapter 14: Message interaction patterns: Covers complex messaging interactions, including multiple requests and responses, timeouts, and message correlation (both system and business).

Chapter 15: Workflow patterns: Looks at how to implement workflows involving complex chains of approval and how to use the Workflow Service API.

Chapter 16: Using business rules to implement services: Here we look at the Rules engine’s inferencing capabilities, and how we can use them to implement types of business services.

Chapter 17: The importance of bindings: Looks at the protocols available in addition to SOAP over HTTP for invoking web services and the advantages they provide.

Section 3 – Other considerations

Chapter 18: Packaging and deployment: Examines how to package up a SOA application for deployment into environments such as test and production.

Chapter 19: Testing composite applications: Looks at how to create, deploy, and run test cases that automate the testing of composite applications.

Chapter 20: Defining security and management policies: Details how to use Web Service Manager to secure and administer SOA applications.
