As you might know by now, Java EE 7 will be released in a few days. There are many new features and I will not cover these novelties now. I just want to mention that most of the XML deployment descriptor namespaces have been updated. Nothing that will change your life as a developer, but as I mentioned on the […]
Update : the book has been published end of June 2013 I have been quiet on my blog lately but there was a reason: I was writing a Beginning Java EE 7 book for APress. I am using the past tense because I’ve finished writing it. I’ve gently started in November 2012 and accelerated the writing pace as I was following the updates of the […]
Stephen Chin had this crazy idea of touring Europe on its way to Devoxx, and interview people. He called it the “Hacking Tour – The Road to Devoxx“. On his way from Italy he crossed France, stopped over to interview several people and then he arrived in Paris to interview me as well as the Parisian Java community (Paris JUG, […]
If you are interested by Java EE development and roadmap you might have read recently that the Cloud feature in Java EE 7 has been delayed. As I’ve already expressed in the Java EE 7 expert group mailing list, I’m happy about this news because I feel standardizing cloud in EE 7 was way too early. But I’m also sad. Sad because […]
How do you configure your enterprise application ? Or to be more precise "what is configuration, what can you configure in Java EE and how can you configure it ?"
What is configuration ?
Sometimes your application needs to change parts of its behavior at deployment time. You then need to provide some external configuration for some components. For example, in your development environment you don't want to use a datasource and instead hit the database with a user & password, in your test environment you lookup for the datasource and use it. If you deploy your application in Europe you need to use the Euro as the current currency and if you deploy it in the US you need dollars...
If you haven't used your RSS feed reader lately, you might have missed that Java EE 7 is starting to kick off : JPA 2.1 (JSR 338) and JAX-RS 2.0 (JSR 339) have been voted, Robert Chinnici has talked about it, some conferences have mentioned it... Java EE 7 will happen and quite quickly (Q4 2012). The main focus is the cloud. I will not talk here about the cloud, I'll talk about everything else (well, not everything ;o)
Java EE 7 is an umbrella specification, meaning it's made of several specifications. Its goal is to give the other JSRs a common target (here, the cloud) and to make sure these specifications interact well with each other. The Java EE 7 expert group is not responsible for all the JSRs, just the umbrella. That means if the Java EE 7 expert group wants to add something new to the platform (eg. it would be nice to have batch processing into the platform) it will not do it : it will rely on some other spec (i.e. someone else) to specify it and to interact well with the other specs.
