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
This new edition of
Professional Java Server Programming J2EE is remarkably similar to the previous edition. Differences include dropping the chapter on Internationalisation and adding chapters on Java Connector Architecture, Web Services, which J2EE implementation to use and J2EE Packaging--along with minor chapter changes reflecting changes to v1.3.
You'll need a good grounding in Java programming and database work at a corporate level, and it helps if you're familiar with RMI, JNDI, JDBC, SOAP, SwA, UDDI and WSDL, though these are introduced in the text. You'll find excellent coverage of the complete servlet lifecycle, deployment, security and other business-oriented aspects of J2EE with emphasis on scalability, robustness and maintainability.
The authors assume familiarity (if not extensive experience) with objects, classes, data exchange protocols and other aspects of server programming--including a grasp of business logic and UML. However, treating business procedures as programming exercises often results in confusion between the business and programming logic. This reflects the problems encountered when trying to treat two activities as if they're aspects of the same exercise, when in practice they're better treated separately--a problem exacerbated by the lack of support in UML for Enterprise Javabeans.
If you persevere, though, Professional Java Server Programming J2EE 1.3 Edition will get you to the finish line, even if it does sometimes feel like you're running an obstacle course. --Steve Patient
