So now I am a NightHacker ;o)

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, […]

I need you for Logging API Spec Lead !

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 […]

Yet Another Petstore !

Do you remember the good old Java Petstore ? It was a sample application created by Sun for its Java BluePrints program. The Java Petstore was designed to illustrate how J2EE (and then Java EE) could be used to develop an eCommerce web application. Yes, the point of the Petstore is to sell pets online. The Petstore had a huge […]

WYTIWYR : What You Test Is What You Run

I'm fed up with unit testing !

It's 2012 and my first resolution of the year is to finally tell the truth about testing : unit testing is pretty much useless when your code runs inside a container. How do you unit test an EJB which relies on the container services (i.e transaction, injection, security...) ? Well, you mock the database access, you mock your security layer, you mock your dependencies, you mock your validation layer... to test what ? A bit of business logic. Yes. Unit test is interesting when you have complex business logic to test so you can have quick feedback. Otherwise, it's a waste of time which doesn't test your container services. So I'm not saying unit testing is completely useless, I'm saying that integration testing is also to be considered when you run your code inside a Java EE container.

O Java EE 6 Application Servers, Where Art Thou?

Nearly two years ago (time flies), when Java EE 6 came out, I wrote a post about application servers where I did some micro benchmarking (basically, startup time). I had plenty of comments and recently I had many people asking for some updates. Witht Java EE 6 booming, with some cloud vendors moving to Java EE 6, it was time to update this microbenchmark and focus on Java EE 6 application servers. BTW, if you want to know what Java EE 6 is, you can check the slides of a presentationI gave a few times.

The benchmark

Same disclaimer as last time : This is not a real benchmark ! so I'll copy paste the paragraph I wrote last time :

In this test I’m just concerned about the usability of an application server for a developer. The idea is to download it, install it, start it and take some measurements : size of download, ease of installation, size of disk, startup time, size of RAM.
