With the release of the IBM WebSphere OpenJPA V2.0 open Alpha, there will be a renewed interest in OpenJPA by those that have not yet learned it. For those that have been using OpenJPA, this release will provide new functions and features. For those that have never used JPA, the Open Alpha site has an excellent getting-started tutorial. This tutorial is a great place to learn the basics. This tutorial is labeled as part 1 and does not require the WebSphere Application Server. It uses J2SE, MySQL and Eclipse.
The tutorial steps through the parts of OpenJPA, including the way it uses annotations, the persistence.xml file and JPQL. To keep it simple and to allow the user maximum flexibility the complete working code is provided.
You can download the tutorial here:

I thoroughly enjoyed reading your snarky review of L.A. Noire! Your observation about the game's strengths—the interrogation and clue-hunting—and its weaknesses—the repetitive gunfights and driving—really resonates. The critique about the game ending with a sewer gunfight instead of an intellectual battle is spot on. It's interesting to see how open-world game design has evolved, and how AI is now being used to create more dynamic characters and narratives in gaming. For professionals in the gaming industry, I've been researching Best Gen AI and Agentic AI certification in Electronic City to understand how AI is transforming game development. Your review is a great reminder of the importance of narrative consistency in game design. Thanks for the thoughtful critique!
