Synopsis

The Java 2 Platform, Enterprise Edition (J2EE) defines a new standard in enterprise solutions through a simplified, component-based development model. By extending the "write-once, run-anywhere(TM)" benefits of the Java programming language to enterprise servers, J2EE adds the scalability, robustness, and security required for today's vital e-commerce and enterprise solutions. The Java 2 Platform, Enterprise Edition: Platform and Components Specifications defines the architecture for developing applications with J2EE. This volume includes:

Java 2 Platform, Enterprise Edition Specification, version 1.2 This specification defines the initial release of the J2EE platform. It discusses application architecture using Java Servlets, JavaServer Pages(TM), Enterprise JavaBeans, and other technologies. It specifies application access to services such as JDBC(TM), Java Transaction API, JavaMail(TM), CORBA connectivity, and others. It also discusses J2EE policies regarding application deployment and security. Enterprise JavaBeans Specification, version 1.1 Enterprise JavaBeans technology provides the standard middle-tier components in the J2EE model. This technology provides simplified support for transaction management and remote object access, and it frees enterprise developers to focus on the business logic of their applications. Version 1.1 of the specification includes a number of enhancements, including mandatory entity beans and XML deployment descriptors. Java Servlet Specification, version 2.2 Java Servlets technology defines a standard for developing server-side behaviors in web applications based on the Java programming language. As part of the J2EE specifications, servlets technology supports development of dynamic web content for e-commerce and other enterprise applications.

JavaServer Pages Specification, version 1.2 The JavaServer Pages (JSP) technology simplifies the development and deployment of interactive web applications. Using an extensible markup language based on HTML and the Java programming language, JSP defines a server-side mechanism to allow content experts greater freedom in creating and displaying dynamic web content.

Developed with the input of a wide range of industry experts, these specifications define a new standard for resolving many complex issues related to developing, deploying, and managing multi-tier enterprise applications.

About this title

Review

Most Java developers rely on application servers and other tools to simplify working with Enterprise JavaBeans (EJBs) and servlets. But how do you build a Java 2 Enterprise Edition (J2EE) EJB server from scratch? Based on the latest standards from Sun, Java 2 Platform, Enterprise Edition: Platform and Component Specifications provides a valuable roadmap for understanding the design philosophy and required features that go into J2EE. This book will also be of interest to the Java expert who wants to see how today's application servers work under the hood.

This title concentrates on the "Enterprise Edition" of Java 2, meaning that "core" features are left out. Instead, the team authors focus on two major areas of Java on the enterprise: servlets (including JavaServer Pages, or JSPs) and Enterprise JavaBeans (EJBs). This text is really two books in one, as both topics get full treatment, from basic features to design goals, required APIs, and the evolution of relevant J2EE standards.

XML is used extensively in J2EE for deployment and configuration, and this book provides XML DTDs (for understanding the tags used to defined particular options) and sample XML files for various aspects of deployment. A highlight here is a DTD for defining JSPs using XML--clearly a promising idea that will add great flexibility to JSP-based Web applications.

Excellent diagrams explain the architecture behind servlets and EJBs. One standout section provides "object interaction" diagrams for EJBs--diagrams that show the life cycle and operation of these components. This material will be useful to anyone who really wants to understand how EJBs work, and it will help readers solve problems running JavaBeans in the real world. Like being an expert on CORBA or COM+, knowing the inner workings of servlets and EJBs will pay off--even if you don't need to write your own application server.

Aimed at the more advanced Java developer, Java 2 Platform, Enterprise Edition delivers an authoritative and detailed guide to what it takes to build an EJB or servlet platform. Read it if you are planning to design such software, or if you want to understand the inner workings of today's powerful J2EE platform. --Richard Dragan
