Service oriented architecture with Java : using SOA and web services to build powerful Java applications

In Detail Service Oriented Architecture provides a way for applications to work together over the Internet. Usually, SOA applications are exposed through web services. Web services have been around for a while, but complex adoption processes and poor standardization hampered their use at first. However, with the adoption of new, simpler protocols such as REST, and major companies supporting SOA, the time is now right to adopt these standards. This book will show you how to build SOA, web services-based applications using Java. You will find out when SOA is the best choice for your application, how to design a sound architecture, and then implement your design using Java. The book covers the important web services protocols: XML-over-HTTP, REST, and SOAP. You will learn how to develop web services at all levels of complexity and for all kinds of business situations. This book shows how to use SOA and web services to build powerful applications in Java. It teaches the concepts and the implementation with best-practice real-world examples. You will learn to design a sound architecture for successful implementation of any business solution, the different types of architecture, and various tenets of SOA. The book explains the fundamentals and the advantages of using the Service Oriented Architecture in designing your business solution. Approach This book is an overview of how to implement SOA using Java with the help of real-world examples. It briefly introduces the theory behind SOA and all the case studies are described from scratch. Who this book is for This book is for Java programmers or architects who are interested in implementing SOA concepts in their applications. Readers should be familiar with Java Enterprise concepts.

In Detail

Service Oriented Architecture provides a way for applications to work together over the Internet. Usually, SOA applications are exposed through web services.

Web services have been around for a while, but complex adoption processes and poor standardization hampered their use at first. However, with the adoption of new, simpler protocols such as REST, and major companies supporting SOA, the time is now right to adopt these standards.

This book will show you how to build SOA, web services-based applications using Java. You will find out when SOA is the best choice for your application, how to design a sound architecture, and then implement your design using Java.

The book covers the important web services protocols: XML-over-HTTP, REST, and SOAP. You will learn how to develop web services at all levels of complexity and for all kinds of business situations.

This book shows how to use SOA and web services to build powerful applications in Java. It teaches the concepts and the implementation with best-practice real-world examples. You will learn to design a sound architecture for successful implementation of any business solution, the different types of architecture, and various tenets of SOA.
