Sams Teach Yourself J2EE in 21 Days, 2nd Ed

J2EE has become required knowledge for any serious Java developer, but learning this large and complex specification requires a substantial investment of time and energy. Sams Teach Yourself J2EE in 21 Days, 2/E presents the enterprise Java architecture in accessible, easy-to-comprehend lessons, describing how each J2EE tool solves the challenges of n-Tier development. Using the architecture as a roadmap, chapters describe Enterprise JavaBeans (EJB), JavaServer Pages (JSP), Java Servlets, and more, giving readers a full understanding of J2EE development.

Further chapters cover the role of XML, custom JSP tags, creating J2EE Web Services, and how Java Connectors allow J2EE applications to interact with legacy and non-Java systems. The book finishes with sample applications which put all the pieces together, including an example using J2EE to create Web Services. Along the way, every concept is illustrated with practical, real-world examples to ensure understanding by Java students as well as experts.

Martin Bond, B.Sc. M.Sc. C.Eng, M.B.C.S., was born in Blackburn, England and went to University at Aberystwyth, Wales to study Pure Maths and Physics.

After graduating Martin did research into large scale software systems until the thought of earning money lured him into the commercial world. Martin was soon managing an R&D team developing parallel processing compilers for the occam language, but preferred to retain his hands-on technical skills and moved in open systems software design and consultancy. Since 1995 Martin has worked primarily as an independent trainer, course writer and technical author specializing in Unix, C, C++, Java and software design. Martin has written training courses on Unix, XML, Java and Solaris Security and co-authored Tomcat Kick Start (Sams Publishing, 2002). Martin currently lives on a smallholding in Cornwall, England.

Andy Longshaw is a consultant, writer, and educator specializing in enterprise platforms, Web-based systems and Web services, particularly the design and architecture decisions required to use these technologies successfully. Andy has been explaining technology for most of the last decade as a consultant, mentor, trainer and conference speaker. A wild rumor suggests that some people have managed to stay awake in these sessions. Despite being well educated and otherwise fairly normal, Andy still subjects himself and his family to "trial by unpredictability" by watching Manchester City FC far more often than is healthy.
