How to use JPA

posted by Roberto Cortez on

Today, my third article How to use JPA correctly to avoid complaints of a slow application was published on RebelLabs. In the last few years I have worked a lot with JPA, so it was a perfect opportunity to write down some of the things I have learned and hopefully help other developers.

A special thanks to RebelLabs for letting me publish my work there and of course to Oliver White for all the support on writing and reviewing the article. You rock!

Interview at Devoxx Belgium 2013

posted by Roberto Cortez on

I had the opportunity to attend last Devoxx in Belgium. It was my first time attending a Devoxx conference and it was an awesome conference. During the event, I joined an Hackergarten organised by Arun Gupta and had the chance to contribute tests for a suit of Java EE 7 Samples in Github. Since I’m very interested in Batch processing, I started to write a few tests for the JSR-352 samples and very quickly we found a possible bug in the specification.

So, Arun Gupta told me how could I report the bug and check all the information related with the JSR-352 and told me about the JCP and the Adopt a JSR processes. The bug that we found was already reported and you can check it here.

I later met Heather VanCura that manages the JCP Program Office and she was very interested in the experience I just had at the Hackergarten. For that reason, I was interviewed to tell my own story and hopefully inspire other developers to contribute to the JCP or the Adopt a JSR processes. Here is the interview:

I continue to contribute to the Java EE 7 Samples project and you are also invited to do so if you wish. I’ve found more bugs and this is my first report and contribution to the Java ecosystem.
