ONJava.com -- Introducing [fleXive] - A Complementary Approach to Java EE 5 Web Development
@ May 01, 2008 10:12 PM 0 comments
At its heart [fleXive] is a pure Java EE 5 application, the core is made up of EJB3 beans, sharing common states and configuration using a clustered cache, while the web layer is based on JSF using Facelets, Richfaces/Ajax4JSF, and the Dojo toolkit. As a persistence alternative to JPA/Hibernate (which can be used as well of course) [fleXive] comes with its own persistence implementation offering some advantages like integrated ACL based security, versioning, support for multilingual data types, inheritance, and reuse.

Java theory and practice: Stick a fork in it, Part 2 [developerWorks]
@ Mar 17, 2008 03:42 AM 0 comments
One of the additions to the java.util.concurrent packages coming in Java 7 is a library for fork-join-style parallel decomposition. In part one of this series, author Brian Goetz shows how fork-join provides a natural mechanism for decomposing many algorithms to effectively exploit hardware parallelism. In this article, he'll cover the ParallelArray classes, which simplify parallel sorting and searching operations on in-memory data structures.
RESTful SOA using XML [developerWorks]
@ Mar 01, 2008 01:37 PM 0 comments
Service Oriented Architecture usually implies heavyweight technology for large enterprises. The advantages of the SOA architectural pattern also apply to smaller environments. To follow SOA principles, you don't necessarily need all the overhead that is useful in larger environments. You can use lightweight principles like REST to do so. This article describes how.
Getting started with JavaServer Faces 1.2, Part 2: JSF life cycle, conversion, validation, and phase list
@ Feb 07, 2008 06:47 AM 0 comments
This tutorial series covers how to get started with Java™ Server Faces (JSF) technology, a server-side framework that offers a component-based approach to Web user-interface development. Part 1 gets you started with a JSF 1.2 overview and a basic application. This sequel gives you a firm grasp of JSF's more-advanced features: custom validators, converters, and phase listeners. Along the way you'll gain an understanding of the JSF application life cycle. [deveoperWorks]
Understanding JPA, Part 1: The object-oriented paradigm of data persistence
@ Jan 22, 2008 01:59 AM 0 comments
Java Persistence API, or JPA, is a standard persistence API introduced as part of the Java EE 5 platform.
In this article, you will see how elegantly data persistence can be handled in an object-oriented manner just with the help of JPA annotations. The article is intended for readers new to JPA who understand the basic concepts of relational database management systems and are familiar with Java 5 annotations. [JavaWorld]
