Do a quick search and you will find yourself staring down volumes of information on linguistics and language models, on data mining, or on the implication of the breakdown of specific proteins on the decline of debutante culture. Okay, I’m kidding about that last one. But if you ...

Spring Batch – Replacing XML Job Configuration With JavaConfig


I recently assisted a client in getting up and running with a Spring Batch implementation. The team had decided to move forward with a JavaConfig-based configuration for their batch jobs instead of the traditional XML-based configuration. As this is becoming a more common approach to configuring Java applications, I felt it was time to update Keyhole’s Spring Batch series to show you how ...

Short on Time? Switch to Groovy for Unit Testing

I have yet to run into a programmer that has not heard of both, nor one that says Unit Testing isn’t important.

Do Primitives Need To Go?


I am currently working on an enterprise application using JSF as the view technology and JPA for the persistence layer. It may have been something in a backing bean or service method, but it struck me: Is there a good reason to use primitives anymore in enterprise applications?
