电子书免费下载 Java 2 Platform, Enterprise Edition: Platform and Component Specifications

The Java 2(TM) 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(TM) 2 Platform, Enterprise Edition: Platform and Components Specifications defines the architecture for developing applications with J2EE. This volume includes:

Java(TM) 2 Platform, Enterprise Edition Specification, version 1.2

This specification defines the initial release of the J2EE platform. It discusses application architecture using Java(TM) Servlets, JavaServer Pages(TM), Enterprise JavaBeans(TM), 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(TM) 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(TM) 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(TM) 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.
