Using a simple, stand-alone program as a point of departure, Java expert Michael Yawn brings you through all the steps and decisions needed to transform this program into a rich, Web-enabled application. Along the way you'll gain a working knowledge of Java 2 Enterprise Edition (J2EE) and the Java APIs for XML (JAX) emerging technologies for writing Web applications and working with XML documents and procedures. Yawn's technique of reworking the example application gives you hands-on experience at adapting software for different purposes and environments, as well as a deep understanding of how to build flexibility into your projects from the outset.
• Web services and Web applications - and underlying technologies - by example
• Layering applications to simplify reworking; using design patterns
• Integrating JavaServer Pages, JavaBeans, Servlets, and custom tag libraries
• XML on the Web and with wireless devices
• Java Message Service, MOM, and XML messaging with SOAP and JAXM
• JAX RPC services and their clients
• Enterprise Java Beans-Session, Message-Driven, and Entity beans
The enclosed CD-ROM includes example code and tools for developing and deploying Web services, including the Xerces and Xalan XML processors, the Struts application framework, and the Tomcat server. In his engaging style, Yawn doesn't simply describe Web applications and services-you'll come away understanding how they all fit together. With the whys well in hand, you'll be a much more effective coder. This book requires only a basic knowledge of Java programming, and its content is applicable to all servers.
