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.
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.

I feel like writing some posts about CDI (Contexts and Dependency Injection). So this is the first one of a series of x posts (0<x<10). I will not go through the entire history of CDI (formerly called Web Beans, splitted in two JSRs… and so on), but will try to give you information on how to use it in different environments, explain you injection, context management, scoping, decorators and so on. So you can think of this series of posts as a humble step by step CDI tutorial. You can also read the very good documentation on the JBoss website (where I got some help and inspiration).

With Java EE 6 and GlassFish v3 out, it is time to take a little break and look at the application server world. J2EE 1.2 was created in 1999, that’s 10 years ago. The application server market at the time was completely different of the one today. There was Weblogic and Websphere, other proprietary application servers (not following J2EE) and no open source application server. … Continue reading O Application Servers, Where Art Thou?
