In the last few weeks I have been rather busy working on a new project with Rick Hightower, who is fairly well known for his training and writings on Spring and JSF, and Rob WIlliams who is a blogger known as much for meddling in new technologies (and getting mad at them) as he is for intertwining various historical and literary references in his posts. The result of this is the CDISource project which aims to advocate and facilitate the use of the JSR 299 – Java Contexts and Dependency Injection framework across the Java landscape.

If you’ve seen my posts or my site before, you’ll no doubt be aware that I have written at great length about Java EE 6, JSF, CDI , EJB and so on. What I haven’t written about is the many frustrations I’ve come up against in dealing with these frameworks on their own and especially when combined, or how their usefulness is often constrained to the application server container.

Java EE in some ways is an archipelago of frameworks that lacks the cohesiveness and all in one wide screen vision that software developers need. Java EE is about the enterprise, in reality its about the web, or even more specifically about Java EE containers. There’s a whole slew of uses for a good type safe and flexible dependency injection and AOP framework and such as CDI outside of Java EE containers but there is very little information and code to make it actually work.

Our goal is to make CDI useful and usable on its own without Java EE 6, and to give developers the tools and information to do so. To let them write vendor neutral and portable code, and apply agile and best practices. Developers know how to write good software and don’t want to sacrifice that for the sake of using a framework to make things easier. To that end we aim to provide code and information that will help facilitate those practices.

There will be some learning for ourselves along the way and we will have to change some of our previously held concepts. I know over the last few weeks having been getting CDI working and useful outside of the web container it has really altered my perspective on how I think about the dependencies and structure in CDI applications. My perspective has changed even more than when I wrote A Little Less Conversation.

As much as I hate to say it, we did come up with a mission statement, although we found it fairly easy and enjoyable to clearly defined the goals and attitudes of the project.

Our mission is to :

• Promote and facilitate the use of the Java Context and Dependency Injection (CDI) framework in relation to as many aspects of application development as possible.
• Enable developers to take advantage of CDI independently of Java EE.
• Provide lightweight, lean and agile access to the underlying CDI container as a core principle in our efforts.
• Make testing easy without requiring a complex set of tools or complex deployment scenarios.
• Enhance both Java EE development as well as the use of CDI in non Java EE application where possible.
• Promote and enable the use of CDI in a vendor neutral environment and maximize the portability of application code across CDI implementations.
• Not reject the ideas of Java EE but expand the usability of CDI outside the borders of Java EE application servers with frameworks that are not a part of the specification.
• Not reject other CDI efforts but to provide another venue to promote those efforts. This is an addition. This is another voice in support of CDI.

We are pretty excited that so far we have been able to live up to the intent of our mission statement with everything we’ve done so far. Over the next few days and weeks you will see articles and tutorials come out of Rick, Rob and I as we write about the CDISource project and we start to showcase some of the code we have written and start giving you an idea of where we are heading.

Right now we have vendor neutral support for starting up CDI outside of the web container and also for testing CDI beans with minimal configuration and intrusion on your test cases. We also have a few other pieces that are nearly ready, as well as dozens of ideas to get started on.
