- Banish Your Resistance to Persistence with the EJB 3.0 Persistence API by Rod Coffin - [Clicks: 200]
With the 3.0 version of EJB, Java's guardians have endeavored to make persistence a gentler beast that borrows the best from other ORM frameworks that have long curried favor with the community. Now, learn how to use the new spec, along with JBoss and Maven, to persist Java objects to a relational database.

http://www.devx.com/Java/Article/30045 - Nov, 2005 - Converting a POJO to a Persistent Entity by Sriramulu Lakkaraju, Abhijit Kumar - [Clicks: 125]
One of the goals of Java EE 5 is ease of development, and the new Java Persistence API that is defined as part of the Enterprise JavaBeans (EJB) 3.0 specification, JSR-220, is a key component designed to meet that goal. The popular Java Servlet API 2.5 also includes some minor changes that support ease of development. In this Tech Tip, you'll see an example of the Java Persistence API in use from a Java Servlet. The example shows you how to convert a POJO (Plain Old Java Object) to a persistent entity, and how to use that entity from a Java Servlet. You'll also have the opportunity to run a sample application that uses these features.

We've all heard about the simplicity and power of the EJB 3.0 specification. And because this has proven to be true, we can't help but think that performance must be rather poor. After all, all that simplicity must come at a price.

This Tech Tip describes how Enterprise JavaBeans 3.0 (EJB 3.0) session beans declare dependencies on external resources, and how dependencies can be injected into EJB 3.0 session beans. The tip also describes how EJB3.0 session beans can refer to the home or business interfaces of enterprise beans using logical names called EJB references. The examples in this tip are based on an open source reference implementation of Java EE 5 called GlassFish.

In this series of two articles, you learn how to develop simpler and more robust enterprise Java applications using the POJO (plain-old Java object) programming model in EJB 3.0. Runnable sample code illustrates the key elements in an EJB 3.0 application. In Part 1, Michael Juntao Yuan covers EJB 3.0 annotations to develop loosely coupled POJO applications and deliver container services to managed POJOs.

In this article, I will examine some key differences behind the Spring and EJB 3.0 frameworks, and discuss their pros and cons. The topics covered in this article also apply to other lesser-known enterprise middleware frameworks, as they all converge on the "loosely coupled POJO" design. I hope this article will help you choose the best framework for your needs.
