Business Process Execution Language (BPEL, also known as WS-BPEL) has become the de facto standard for orchestrating services in SOA composite applications. It enables automation of business processes, reduces the gap between business requirements and applications, and allows better alignment between business processes and underlying IT architecture. BPEL is an open specification and one of the most important pieces of SOA. Therefore, learning BPEL is essential for successful adoption of SOA and for the development of composite applications.
This book provides a fast-paced practical introduction to WS-BPEL, one of the centerpieces of SOA. It covers the most important features of BPEL 2.0 and provides several real-world examples to underline its concepts. In addition to BPEL specifications, the book provides comprehensive coverage of BPEL support in JDeveloper and Oracle SOA Suite.
This book starts with an introduction to BPEL. It first teaches you how to develop your first BPEL process and understand the basic structure of BPEL processes. It will then move on to explain the core concepts such as invoking services, synchronous and asynchronous processes, partner links, the role of WSDL, variables, flows, and more.
Moving ahead, this book will make you familiar with concepts such as human tasks, fault handling, transaction management and compensation handling, scopes, events and event handlers, concurrent activities and links.
The book takes a fast-paced practical approach to WS-BPEL design and development based on practical examples and clear descriptions of the most important usage scenarios. This book is all you need to get up and running with WS-BPEL development.
A systematic guide for beginners which focuses on getting you up and running with building BPEL processes and learning the BPEL language with clear instructions and examples.
Who this book is for
If you are a software architect, a designer, a software developer, an SOA and BPM architect, a project manager, or a business process analyst who is responsible for the design and development of business processes, composite applications, and BPM/SOA solutions, then this book is for you. You should have a clear grasp of general SOA concepts including business processes and web services, but no prior knowledge of the BPEL language is required.
