Up to Derby 10.4.2.0, the in-memory database mode wasn’t a real one because data was stored into files onto your disk. The new 10.5.1.1 supports a real in-memory mode were data is only stored in memory, with no files being created. As stated in the new features page : Initial implementation of a storage engine for Derby where all data is kept in memory. There … Continue reading Derby 10.5.1.1 is really an in-memory database
As you might know with JPA, the META-INF/persistence.xml file defines a persistence unit with some provider’s properties. For example, if you are using JPA in a Java SE environment, you will have to define the JDBC driver, database connexion (user and password), database URL and so forth. In JPA 1.0 these properties were not standard, so for each persistence provider you would have to use … Continue reading JPA 2.0 : standard properties in persistence.xml
On my previous post I explained how painful it was to copy resources (files, librairies…) with Maven and the maven-resources-plugin. And guess what ? I received 2 emails from Maven lovers telling me that for this kind of task, Antrun would be more appropriate. So I thought I should give it a try to be fully honest with me, Maven, and God (you need a … Continue reading Copying resources to JBoss with Maven (and Antrun)
In my project, we use Maven to compile, build, package and deploy our application to JBoss 4.3. Every works fine. But each time a new developer comes along, or when we need to install a new server, we always have to remember to deploy the datasource and copy the MySQL JDBC Driver to JBoss. Nothing too complicated, but we tend to forget it. The file … Continue reading Copying resources to JBoss with Maven

For those of you who have followed the entire debate between JCDI (Java Context & Dependency Injection, aka Web Beans) and @Inject, you will be pleased (or not) to know that there is a brand new JSR : JSR 330 Dependency Injection for Java. I hope we are not starting a new battle like the one between Java Module (JSR 277), … Continue reading JSR 330

Last year I have been approached by Apress who proposed me to write a book about Java EE 6 in the From Novice to Professional collection. At first I … Continue reading A book about Java EE 6

Then at Java One (with the same folks) and in May Patrick Curran came to the Paris JUG … and now a BOF at Devoxx with Corina Ulescu about this sensible topic. The … Continue reading Everybody should be able to easily observe JSRs
I have two passions : Java and Music. And recently, I faced a common problem while trying to explain Why I love EJBs and Why I love Genesis When I say I love Genesis, I’m talking about the version 1.0 of the band. The one from 1967 to 1975 (even 1977) when it was a progressive rock formation. Then Peter Gabriel left, Phil Collins stopped … Continue reading Genesis, EJBs… it depends which version

If you are around, do come. It‘s free and full of interesting speakers talking about open source. Continue reading Speaking at the Open Source conference in Paris
Unit testing is an important topic in projects. J2EE has suffered from a lack of testability and, clearly, got overtaken by light open source containers. Java EE 6 is taking that into account and unit testing an EBJ, for example, will be simple and standardised (through a embeddable container API). As Roberto Chinnici mentioned on his blog, Java EE 6 is scheduled for Q1 2009… … Continue reading Tutorials on Java EE 6 testability
The other day I was at a bar talking to a friend about Entity Beans CMP. We both agreed that, today, this ORM model is crap. But he said, at the time it was created, it was the best we could do In general I would agree with that. We can’t say that the plane of the Wright brothers was crap. Compare with today, it … Continue reading A brief history of Object Relational Mapping

The first edition of my Java EE 5 book has been sold out ! In fact it’s 2500 copies that have been sold in 14 months.

So, it’s a best seller (JK Rolling , if you read … Continue reading Java EE 5, second edition

It was about installing GlassFish, deploying an application, monitor and configure resources as well … Continue reading Back from the TSS Symposium in Prague
It‘s the third time I‘ve been asked if in JPA you can persist the attributes of your entity in several tables. The answer is yes. It has a performance impact (each simple query will use joins) but it can be very helpful when you need to map your objects into an existing database. Here is an example of an Address entity that persist its data … Continue reading Primary and secondary table with JPA
