内容説明

Following in the successful tradition of previous Java Series Tutorials, The JavaaA A TM Web Services Tutorial, Early Access Edition, offers an essential, example-driven resource for every programmer interested in developing and deploying web services and web applications with the Java WSDP. The authors - senior documentation specialists at Sun - offer a concise, all-in-one guide covering the key technologies for building Web services using the Java 2 Platform. They provide practical techniques and examples for working with JavaaA A (tm) Servlets, JSPaA A TM, JSTL and the Java XML Pack to get programmers up to speed. This tutorial is packed with practical examples to reinforce key concepts. Both the tutorial and Sun Microsystems' Web Services Pack are included on the accompanying CD-ROM.
