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.
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.
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.
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.
We have released Jersey 1.19, the open source, production quality, reference implementation of JAX-RS 1.1. The JAX-RS 1.1 specification is available at the JCP web site and also available in non-normative HTML here.
For an overview of JAX-RS features read the Jersey user guide. To get started with Jersey read the getting started section of that guide. To understand more about what Jersey depends on read the dependencies section of that guide. See change log here.
There were many performance improvements since Jersey 2 first came out almost 2 years ago. Jakub and I decided to present some of the latest ones in our recent articles. Jakub took a look at general performance gains in Jersey in his Jersey 2 Performance. I’ll try to cover the change we introduced in Jersey 2.16 and that affected processing and performance of sub-resource locators in Jersey applications.
Support for Entity Filtering in Jersey introduces a convenient facility for reducing the amount of data exchanged over the wire between client and server without a need to create specialized data view components. The main idea behind this feature is to give you means that will let you selectively filter out any non-relevant data from the model before sending the data to the other party.
Entity Data Filtering is not a new feature but so far the support was limited to MOXy JSON provider. Since Jersey 2.16, we support also Jackson (2.x) JSON processor and in this article we’re going to take a look into it in more detail.
Yesterday I was given the opportunity to speak at our local Java User Group meeting (CZJUG). I was covering two topics – JAX-RS.next and Reactive Jersey Client. In this post I’d like to share the used slide-decks and some additional resources.
In this article I’d like to introduce some of the new features, important bug fixes and other noteworthy changes.
Reactive Jersey Client API is a generic API allowing end users to utilize the popular reactive programming model when using Jersey Client. This part of the series describes SPI and implementation of support for custom reactive libraries.
