Opis: SOA with Java - Andre Tost, Philip Thomas, Satadru Roy

"An outstanding depth-and-breadth resource for IT architects and Java professionals to understand and apply the marriage of SOA and modern Java." --Antonio Bruno, Enterprise Architecture and Strategy, digitalStrom "A great self-contained book on SOA using flexible Java implementations..." --Roger Stoffers, Hewlett Packard "Provides clarity on abstract concepts and is filled with concrete examples of implementing SOA principles in Java environments." --Sanjay Singh, Certified SOA Architect "...provides a holistic, comprehensive view on leveraging SOA principles and architecture for building and deploying performant Java services." --Suzanne D'Souza, KBACE Technologies "Thomas Erl's series of books on services technology have shaped, influenced, and strengthened a whole community of enterprise and solution architects' thinking and solution development, and the much awaited SOA with Java book is an excellent addition to the series. It is a must-read." --Lalatendu Rath, Wipro Technologies The Definitive Guide to Building Service-Oriented Solutions with Lightweight and Mainstream Java Technologies Java has evolved into an exceptional platform for building Web-based enterprise services. In SOA with Java, Thomas Erl and several world-class experts guide you in mastering the principles, best practices, and Java technologies you need to design and deliver high-value services and service-oriented solutions. You'll learn how to implement SOA with lightweight frameworks, mainstream Java services technologies, and contemporary specifications and standards. To demonstrate real-world examples, the authors present multiple case study scenarios. They further demystify complex concepts with a plain-English writing style. This book will be valuable to all developers, analysts, architects, and other IT professionals who want to design and implement Web-based service-oriented architectures and enterprise solutions with Java technologies. Topic Areas * Applying modern service-orientation principles to modern Java technology platforms* Leveraging Java infrastructure extensions relevant to service-oriented solutions* Exploring key concepts associated with SOA and service-orientation within the context of Java* Reviewing relevant Java platforms, technologies, and APIs* Understanding the standards and conventions that REST and SOAP services are built upon in relation to Java implementations* Building Java Web-based services with JAX-WS and JAX-RS* Applying the eight key principles of service-orientation design using Java tools and technologies* Creating Java utility services: architectural, design, and implementation issues* Constructing effective entity services: service contracts, messages, data access, and processing* Constructing task services, including detailed guidance on service composition* Using ESBs to support infrastructure requirements in complex services ecosystemsForeword xix CHAPTER 1: Introduction 1 1.1 About This Book 2 Objectives of This Book 2 Who This Book Is For 2 What This Book Does Not Cover 3 1.2 Prerequisite Reading 3 How This Book Is Organized 4 1.3 How Principles and Patterns Are Used in This Book 7 1.4 Symbols and Figures 7 1.5 Additional Information 7 Updates, Errata, and Resources (www.servicetechbooks.com) 8 Referenced Specifications (www.servicetechspecs.com) 8 The Service Technology Magazine (www.servicetechmag.com) 8 Service-Orientation (www.serviceorientation.com) 8 What Is REST?
