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...

JAX-RS Providers on Client and on Server

In this article I'd like to explain two things. First, what to do when you want to restrict JAX-RS providers to be used on, for example, client-side only. And second, what are the issues (and how to solve them) with injecting providers when you create and register instances of them directly. Constraining JAX-RS providers to particular runtime Some of the JAX-RS providers can be used on the server-side as well as on the client-side. The reusability of providers was among...

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. See my original post on blog.dejavu.sk →

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. See my original post on...

Jersey Monthly Newsletter – February 2015

Jersey team has become more active in writing blog posts so I’ve decided to give it a try and publish a short summary of these posts and maybe something more at the end of each month. This first post focuses heavily on Jersey but I’d like to include interesting articles from more sources about the world of JAX-RS and REST services in the next months. At the beginning I’d like to mention a page where you can always find information about the latest released Jersey 1.x and 2.x....

Micro-Benchmarking JAX-RS Applications

Sometimes you want to examine what impact would a new JAX-RS filter have on performance of your application. Whether your custom message body provider is as fast as you though or you simply want to find out the throughput of your JAX-RS resources or client instances. Recently we were looking into this area and we’ve created few utilities that may make your life easier if you want to write micro-benchmarks for JAX-RS applications. Benchmarks I am going to focus on are based on J...
