The release of the 1.3 version of the Java 2 Platform, Enterprise Edition (J2EE) represents the evolution of Sun Microsystems' server-side development platform into a more mature and sophisticated specification. Servlets 2.3 gain events and filtering; JavaServer Pages (JSP) 1.2 gain a new XML syntax and enhancements to the custom tag mechanisms; and Enterprise JavaBeans (EJB) 2.0 has some significant changes to its container-managed persistence model, as well as support for asynchronous processing with the new message-driven beans.
This book demonstrates how to design and construct secure and scalable n-tier J2EE applications, using JSP and servlets for the web tier and EJBs for the business logic. It also covers J2EE Connector Architecture that allows you to easily integrate your J2EE applications to enterprise information systems.
This book covers:
The J2EE container architecture and runtime services
Web component development with Servlets 2.3 and JavaServer Pages 1.2
Business logic components with EJB 2.0, including container-managed persistence, EJB QL, and message-driven beans
Underlying J2EE technologies for distributed development - RMI, JDBC and JNDI
Introduction to Web Services covering SOAP, SwA, WSDL, and UDDI
Aimed at the working developer or IT manager tackling server-side and Web-based enterprise Java applications, Professional Java Server Programming J2EE 1.3 Edition offers a truly excellent guide to the fast-changing world of today's Java 2 Enterprise Edition (J2EE) APIs and programming techniques. Filled with the practical details and advice for using real Java tools in actual projects, this book offers one of the best available resources to the current state of the Java used on the enterprise.
If anything, the new edition of this title (without the massive hard-cover format of its predecessor) gains in being streamlined. Although some readers might quibble with the ordering of topics here (it's hard to see why JNDI and RMI begin the tour of J2EE), the range of topics and coverage offers a superior mix of APIs without getting bogged down in excessive detail. Better yet, the authors are careful to distinguish between different flavors of specific APIs on such topics as JDBC (they cover features of versions 1.0 through 3.0 separately), new servlet and custom tag library standards, and EJB 2.0 standards. J2EE is several years old and its APIs have grown by leaps and bounds. The authors are careful to cover the older material while highlighting what's new and improved. At each juncture, they do a fine job of listing relevant APIs, making this book an excellent reference for everyday programming.
It's an old saw that the genius is in the details, but perhaps never more so than with J2EE, where finicky application servers can waste countless hours of your time. This volume will increase your productivity with its exacting presentation of Web and EJB deployment (using freeware Java deployment tools) and the league-leading BEA WebLogic Server 6.x, which is used here for deploying components. Working Java developers will also appreciate the full tour of deployment descriptor options for servlets and EJBs.
Other excellent material looks at the ways of designing truly scalable and maintainable enterprise systems with Java mixing JSPs, servlets, and EJBs. This guide to "best practices" includes a useful discussion of software patterns (like the front controller pattern) illustrated with real code. Coverage of custom tag libraries, plus the evolving JSP Standard Tag Library (JSPTL) from Sun and Apache, will help you master this very important emerging technology.
With its extensive coverage of today's rich and complex J2EE platform, and practical focus on real-world design and deployment, the new edition of this book succeeds as an almost indispensable resource for any enterprise Java developer. It will serve as both a reference and tutorial to the latest in high-end Java for your next large-scale project. --Richard Dragan
