What to do when JAX-RS cannot find it’s Providers aka My message body writer is not used

One of the reasons why I wrote this article is my, rather unusual, encounter with a missing message body writer in a Jersey 1 test application. This problem of mine occurred during collecting of data to get a Jersey 1 performance baseline in order to see where Jersey 2 stands when compared to its predecessor. The problem is described at the end of this article because I think it’s pretty rare, but still not impossible :-), and not many of you will (hopefully) face it. But first I’d like to take a look at more common issues regarding missing providers and what you can do to solve them.

Jersey CDI Integration – Few Notes and EAR Support

During our last sprint I was porting support for CDI injections for EARs that contain multiple JAX-RS web applications (WARs). This worked fine in Jersey 1 and it works on WebLogic but we didn’t have support for these kind of deployments directly in Jersey (which means that Glassfish was affected as well) until this very moment. I’d like to share some findings I’ve made while working on this task.

Checkstyle matters to Jersey too …

Last week Pavel wrote and published an interesting blog post about Why Checkstyle matters … I remember how he was describing his encounter with JeroMQ to me. Especially the part where he wasn’t able to build the project for a few times because of the Checkstyle issues that pop-up right after he executed the build. I found the whole idea behind running code style checks during build appealing as well and decided to do something similar for Jersey.
