Comparing JSF Beans, CDI Beans and EJBs

Andy Gibson Articles

There’s still a lot of confusion over the difference types of managed beans provided in Java EE 6 with EJBs, CDI beans and JSF managed beans all being available. This article aims to clear up some of the differences between the them and define when to use them.

Implementing Spring MVC with CDI and Java EE 6 part 2

Andy Gibson Articles

In this second article on implementing Spring MVC in Java EE 6 we’ll take the metadata we extracted in part one and use it to invoke request mapped controller methods in response to web requests and then direct the user to a web page based on the result of the method.

Implementing Spring MVC with CDI and Java EE 6 part 1

Andy Gibson Articles

One of the opinions I’ve had over the last couple of years is that Spring makes things look really easy, and CDI is a great dependency injection framework. Throw in this article suggesting you can build your own Java EE 7 and it sounds like a challenge, so for fun, I thought I might have […]

Announcing CDISource

Andy Gibson Articles

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 […]

Simple RESTful services in Glassfish Pt 2

Andy Gibson Tutorials

In part 2 of this article, we are going to create a data driven web service that will return JSON and XML to the client, and then use jQuery to add a new item to the database and display it in our page.

JBoss Java EE 6 spec dependency in Maven

Andy Gibson QuickBytes

Adam Bien wrote about the Troubled with the crippled Java EE 6 APIs in Maven and a solution for them. Another solution has presented itself now that JBoss has finalized the Java EE 6 spec pom and added it to their public repositories as of early January 2011. You can include the spec in your […]

A Little Less Conversation…

Andy Gibson Articles

One thing that I wrote that I haven’t really gotten around to examining and verifying in closer detail and validating my position on is the production of the conversational entity manager in the Knappsack archetypes. This article looks at this and re-evaluates my thinking on the use of conversational contexts in CDI.

Handling missing resources with CDI Events

Andy Gibson Articles

In part 1, we created a simple application that made use of string resource bundles in JSF and in part 2 we extended it by using CDI to inject the resource provider into beans so we can re-use our code for accessing locale specific string based resources.

Injecting String Resource Services with CDI

Andy Gibson Articles

In this post we looked at adding String resource bundles to our JSF applications to move our string constants into external resources that we can define for different locales. Now I want to extend that example to show how you can expand on that by using injection to access those resources.

CDI @Alternative Info

Andy Gibson QuickBytes

The @Alternative CDI annotation allows you to have multiple matching dependencies for a given injection point. This means you can define beans that provide implementations for the same interface without worrying about ambigious dependency errors. When you mark a class with the @Alternative annotation, it is effectively disabled and cannot be considered for injection. The […]
