Riassunto

This book for architects and senior developers responsible for setting up Service-Oriented Architecture (SOA) for intra-enterprise application integration (EAI) and inter-enterprise (B2B) integration focuses on process-centric SOA to integrate existing (legacy) applications and modern solutions, using new technologies: web services, XML, Enterprise Services Busses (ESBs), and Business Process Execution Language (BPEL). Application integration within and between businesses to make up-to-date information accessible almost anywhere is a difficult task that is growing in importance. This book shows how to best integrate applications developed in different architectures and programming languages on different platforms with modern e-business solutions, develop web services, and process and manage XML documents from the JEE and .NET platforms. It demonstrates how to use ESBs for service integration and BPEL executable business processes for service composition into business processes.

Contenuti

In Chapter 1 you will get an overview of the challenges in integration and learn why integration is one of the most difficult problems in application development. We also identify the best strategies for SOA-based integration and discuss top-down, bottom-up, and inside-out approaches. You will learn about different types of integration, such as data-level integration, application integration, business process integration, presentation integration, and also B2B integration.

Chapter 2 will help you understand what SOA is. You will see that SOA is a very comprehensive enterprise integration paradigm that builds on many existing concepts. Web services standards provide a strong foundation for SOA infrastructure. You will also learn about the Enterprise Services Bus which is presently one of the leading integration infrastructure options.

Chapter 3 discusses various design anomalies that may arise while designing XML schemas. Some of the broad categories covered in this chapter are design recommendations for architecting domain-specific XML Schemas, tips for designing XML schemas with examples, using XSL effectively for translating Infosets from one form to another, securing XML documents with encryption and digital signature, and XML serialization and the differences between SAX, DOM, and StAX.

Chapter 4 discusses the architecture of web services and its benefits. The chapter provides an in-depth coverage of the various patterns that can be applied while creating SOA using web services. You will learn the essential differences between EAI and B2B and how to apply SOA integration techniques in this space. The chapter also discusses several guidelines for creating interoperable web services. Finally, a complete, albeit trivial, example of creating web services on the .NET and Java EE platforms is discussed.

In Chapter 5, you will become familiar with the BPEL language and a process-oriented approach to integration. The characteristics of process-oriented integration architectures are discussed. You will learn how to identify business services and service lifecycles. Then the role of executable business processes, which reduce the semantic gap between business and IT, is explained. The chapter introduces the most important technology—BPEL. You will learn about characteristics of BPEL and identify the differences between executable and abstract processes. The basic BPEL concepts and the role of WSDL will be discussed.

In Chapter 6, you will see how ESB provides a concrete infrastructure for SOA, extending the simple services model to include a robust services bus with extensive mediation functionality.
