EJB 3.0 and Spring 2.5

For those of you who are interested in using EJB 3.0 components in Spring, I have written a detailed How-to article at Javalobby. This article shows you how easily you can call EJB 3.0 session beans from within your Spring beans.

Also, some interesting comments from readers and a few from Reza Rehman co-author of the "EJB3 in Action" book.

UML Diagrams from NetBeans

Based on the article I wrote at Javalobby: Reverse-engineer Source Code into UML Diagrams, my DZone colleague Geertjan Wielenga has written another article on how to generate these UML Diagrams from within the NetBeans IDE, called Generate UML Diagrams into Javadoc in NetBeans Projects.

I especially liked the way Geertjan starts off his article by saying:

One incredibly useful article recently on Javalobby is called Reverse-engineer Source Code into UML Diagrams, by Meera Subbarao.

Take a look at your leisure.

Reverse-engineer Source Code into UML Diagrams

I wrote an article at Javalobby and testearly about how to use UMLGraph to generate UML diagrams from existing source code, how to integrate these within your build file, and also use the Ant targets within Hudson CI job, and keep your code base and the UML diagrams in sync. I also show how to include these ant targets in your commit builds or nightly builds of your CI jobs, and also publish these artifacts as part of the post build process.

The article shows how easy and simple it is to include UML diagrams within your Javadoc and also keep them updated with every change in the source code repository. We can do these in less than a few minutes, and in a few simple steps.

Getting started with UmlGraph takes five steps:

1. Download the source code for UMlGraph.
2. Download and install Graphviz.
3. Make changes to your Ant build file.
4. Run the Ant target.
5. Add this target to your CI job.

The above 5 steps are covered in detail in the article.

Take a look at the article, and share your thoughts. The response has been amazingly good for this article.

Spring's so Groovy

Just yesterday, I wrote an article at testearly.com about how easy it was to use Groovy within Spring. I was reading the book "Spring Recipes - A Problem-Solution Approach", and the last chapter is about "Scripting in Spring".

I wrote a simple "HelloWorldService" in Eclipse IDE following the samples provided by this book. Trust me, it was so easy.

In this tutorial written at testearly, you will learn how to use Groovy with Spring, using an external script source file, how to refresh changes when a script source file is changed, and finally see an inline script which was embedded within the Spring configuration file.

Have you used Spring and Groovy? If so, do you mind sharing your thoughts?

P.S: Stay tuned for a detailed review of the book "Spring Recipes - A Problem-Solution Approach" at Javalobby.
