Ever since the first version of Java Technology hit the streets, performance has been an important issue for Java developers. Java has improved dramatically and continually but, performance tuning is very essential to get the best results, especially when we think of J2EE applications.

J2EE is a technology that aims to simplify the design and implementation of enterprise applications. In this tutorial you will learn what J2EE is, its benefits, J2EE main components, Evolution of Enterprise Application Frameworks, Why use J2EE, J2EE Platform Architecture, J2EE APIs and Technologies and J2EE Reference Implementation. Before continuing our J2EE discussion lets define what an enterprise application is.

This article goes into details of how Java as a development technology can help developers to keep their applications simple and secure. Simple mean all way – it should be simple to code, modify, maintain, fix and deliver. Also we are going to cover security aspects of Java technology.

JDK 5.0 added major new support for developing concurrent applications, including JVM changes, new low-level synchronization utilities, and higher-level, thread-safe, high-performance concurrency classes such as thread pools, concurrent collections, semaphores, latches, and barriers. Learn how these new classes can help make your code faster, more scalable, more reliable, and easier to maintain.

Annotations, a new feature in J2SE 5.0 (Tiger), brings a much-needed metadata facility to the core Java language. In this first of a two-part series, author Brett McLaughlin explains why metadata is so useful, introduces you to annotations in the Java language, and delves into Tiger's built-in annotations. Part 2 covers custom annotations.

Tuning isn't always about speed, sometimes other aspects of the application need fixing. When your application needs tuning, your first course of action is normally to monitor the application with a profiler. But profiling is not always practical -- sometimes for ironic reasons. In this installment of Eye on performance, Jack Shirazi and Kirk Pepperdine, Director and CTO of Java Performance Tuning relate their recent experiences with profiling a fat client -- so fat, in fact, that it left no room for a profiler.

The IBM Reflexive User Interface Builder (RIB), a new technology available from alphaWorks, is an application and toolkit for building and rendering Java AWT/Swing and Eclipse SWT GUIs. RIB specifies a flexible and easy-to-use XML markup language for describing Java GUIs and provides an engine for creating them. You can use RIB to test and evaluate basic GUI layout and functionality, or to create and render GUIs for an application.

This article examines two data management strategies available on the Java platform: Java object serialization and Java Database Connectivity (JDBC). While neither data management strategy is inherently superior or inferior to the other, when it comes to managing enterprise information systems, JDBC wins hands down.

In server-side control architectures a majority of the control events must be handled on the server side to update the state of the control. For every user event, the entire page data is sent back to the server as part of the form submission, even data that has not changed or is not affected by the user event. This article shows you how to use containers to overcome data-processing redundancy, which can otherwise drain the life out of your handheld or Web server.

Most Java programmers use some kind of tracing system to keep track of potential errors and problems in code under development. However, multithreaded and multiplatform systems can generate a large and baffling amount of tracing data. This article offers tips that will help you make sense of trace data from complex applications.

In an enterprise environment, you can easily end up in a tangle of modules with a number of third-party libraries and frameworks. While a number of tools are available to aid you in comprehending complex programs, most are expensive and time-consuming to learn. Aspect-oriented programming can be applied to a wide range of programming scenarios, including the comprehension and maintenance of legacy applications.

People who aren't familiar with XP are bothered by the concept of just-in-time (JIT) design -- designing and implementing what you know you need right now and not worrying about future design issues until absolutely necessary. While this approach might seem unwise or even reckless, XP advocate Roy Miller wraps up his series by showing you how safe and easy JIT design is -- and how it just might revolutionize the way you write code.
