Book Description

Spring Web Services is a product of the Spring community focused on creating document-driven Web services.

Spring Web Services aims to facilitate contract-first SOAP service development, allowing for the creation of flexible web services using one of the many ways to manipulate XML payloads.

This comprehensive guide — which provides professional expertise on a variety of technical topics right from setting-up a contract-first Web-Service, creating client of a Web-Service to serialization, monitoring, testing and security using Spring-WS — helps you enhance your skills in Spring Web Services.

Spring Web Services 2 Cookbook includes a wide variety of recipes that covers most important topics used in real-world applications. It is a well-rounded guide covering a lot of ground in the Spring Web Services domain using systematic arranged chapters and focused recipes.

The book begins with setting up a contract first Web Service over various protocols such as JMS, XMPP, and Email. The next chapter targets creating clients for SOAP Web Services. We then learn how to test and monitor the Web Service using tools like soapUI and TCPMon. Building on, logging, tracing and exception handling are detailed in the subsequent chapter. The book then covers marshalling and unmarshalling using different technologies like JAXB2, XMLBeans, JibX, XStream, MooseXML etc. Securing WebServices through authentication, authorization, encryption and decryption and digital signature using Spring-WS features based on XWSS and WSS4J Libraries is outlined in the next chapter two chapters.
