Java 2 Enterprise Edition (J2EE) is the specification that all enterprise Java developers need to build multi-tier applications, and also the basis for BEA’s WebLogic Application Server and IBM’s WebSphere. Revised to be current with the significant J2EE 1.4 update that will drive substantial developer interest. Written by a top-selling team of eleven experts who provide unique and substantial business examples in a vendor-neutral format, making the information applicable to various application servers. Covers patterns, J2EE application servers, frameworks, Ant, and continuous availability.

Provides an introduction to J2EE using the WebLogic platform, which claims the largest market share-about forty percent-of the Java application server market. Features the most comprehensive coverage of the component types of WebLogic in the friendly For Dummies style. Covers static resources, JSPs, taglibs and servlets, EJBs, and WebLogic’s Web service development and deployment capabilities and tools. Teaches readers the basic administration and monitoring capabilities built into WebLogic, using a conversational and example-driven approach.

A software system is the realization of a set of concerns. One of the central premises of object-oriented programming is that each concern should be implemented as a separate module. However, there are certain system-wide concerns, such as logging, security, performance, and so forth, that often need to be addressed in many, if not all of the modules. Consequently, the code to handle these system-wide concerns may be mixed in with the core logic of a huge number of modules, resulting in lower productivity, poor quality, and systems that are hard to evolve.

A guide to the topics required for state of the art web development, this book covers wide-ranging topics, including a variety of web development frameworks and best practices. Beginning with coverage of the history of the architecture of web applications, highlighting the uses of the standard web API to create applications with increasingly sophisticated architectures, developers are led through a discussion on the development of industry accepted best practices for architecture.

A few years ago, the hype surrounding applets put Java on the map as a programming language for the Web. Today, Java servlets stand poised to take Java to the next level as a Web development language. The main reason is that servlets offer a fast, powerful, portable replacement for CGI scripts.

No matter what language they’re programming in, developers always wish things would run faster! Especially when writing mission-critical applications, no one wants to be limited by the programming environment.Java Performance Tuning provides all the details you need to know to “performance tune” any type of Java program and make Java code run significantly faster.
