Articles, notes and random thoughts on Software Development and Technology
Maven goes beyond the typical build and deploy tasks of build tools like Ant, and also provides facilities to generate and deploy skeleton project website and document for the project, and then publish the documentation to a website.
OnJava.com have a link to a sample chapter from the book ‘Maven: A Developers Notebook’, which explains how to use this feature.
Brandon Werner has an interesting article on JavaLobby.com looking at how typically the ServiceLocator pattern has been implemented prior to EJB3.0, and whether or not it will be needed with EJB3.0.
The ServiceLocator has been called a ‘compensating pattern’, one of a collection of patterns from the J2EE Core Patterns book by Sun that are viewed by many as patterns that attempt to negate some of the disadvantages and complexities of dealing with J2EE. They are know as ‘compensating’, because the general opinion has been if EJBs were designed right in the first place, we wouldn’t need the majority of these patterns in the first place.
Werner shows in his article how the ServiceLocator pattern is used to hide the complexities of looking up JNDI resources, and compares to how this is implemented in EJB3.0 using annotations and Dependency Injection. The EJB3.0 approach is much simpler and cleaner, and yes, in this case, we would no longer to use an approach like the ServiceLocator.
Tim Wagner manages the Web Tools Project (WTP) for Eclipse, whose goal is to add J2EE enabling features to Eclipse to support developers building J2EE applications.
In this interview with Tim, he explains what the platform is about, how the project came about, and who the platform is aimed at.
BEA’s Dev2Dev site have a good article on using Spring AOP to simplify the development of an EJB application.
The article introdcues the concept of delegating responsibility from the EJB Bean impl to Spring managed beans, and the use of annotations to generate Home and Remote interfaces.
