In Relation To

The question of backward compatibility is something that all framework developers wrestle with. The term means different things to different people:

It's been a while since the last blog entry and any MC DZone article. So, this entry is what will change this fact. :-)

Today, Red Hat submitted the final draft of JSR-299[1], which now goes under the moniker CDI (Contexts and Dependency Injection), along with the Reference Implementation and TCK. Check out the spec[1] and Javadoc.

That's now official, the Bean Validation specification has been voted YES by the JCP expert committee. That's the culmination of two and a half years of work. (I know the vote has ended nov 2nd but nobody told me ;) )

Steve mentioned in his Hibernate 3.5.0 Beta2 blog entry briefly the Hibernate Static Metamodel Generator Annotation Processor. Time to have a closer look what this annotation processor actually does.

I just noticed that CDI makes it possible to write properties files in Java, instead of plain text. I'm not sure if this is useful, but it is cute.

I put a whole bunch of work into the Javadoc for CDI recently. You can see it here. There's a good overview of the spec in the package doc for javax.enterprise.inject.

Nick Belaevski is the RichFaces dev lead in Minsk and has officially joined the JSF 2.0 Expert Group (JSR-314) along with Alex Smirnov to represent RichFaces and Exadel. As many of you know Dan Allen and Pete Muir are also on the JSF 2.0 Expert Group representing Red Hat & JBoss. Together these 4 people along with the rest of the EG will continue to help advance JSF as a standard and a technology.

Hibernate Validator 4.0.2 is now available for download. This release was necessary for the JCP integration efforts for JSR-303 and addresses a potential NullPointerException (HV-263). Refer to the 4.0.2 release notes for a full list of changes.

Suppose we have an external resource, a database, let's say, that we want to be able to change depending upon the deployment environment. In CDI, we declare resources using a producer field declaration.
