Java Records, one of the major highlights of the Java 16 release, provides a concise and immutable way to define classes for modelling data. This conciseness lends itself useful in a typical Jakarta EE application that can have a number of layers that need to share data. For example the data layer might want to return a subset of a given data set to a calling client through a data projection object. The REST layer might want to have separate entities for server and client side among others. This blog post explores the adoption of Java Records in a Jakarta EE application as a data transfer and projection object.

The Lombok project is a Java library that aims at “spicing up your java.” Started back in 2009, it consists mostly of annotations that can be used on Java classes to generate helpful constructs like getters and setters. It aims at freeing you from writing quite a number of the ceremonial boilerplate code that you sometimes need to write as part of your everyday use of Java. 

YAML is a simple, human-friendly data serialization language for all programming languages. It is the main format for working with Docker. As a language agnostic format, there are many bindings for all the major programming languages. You can easily consume and return data in the YAML format in your Jakarta REST application using message body readers and writers.

Oftentimes in a Jakarta REST application, you may need to access some metadata about a given resource method matched by the Jakarta REST runtime, outside of a resource class. This could be so as to dynamically alter the client's request based on some custom business requirement, or for informative purposes. For example, in a Jakarta REST component like an exception mapper, you might want to get the currently matched resource method and get its HTTP method. 

Are you an Enterprise Java Developer? Or even a Java developer? If yes, then here is your chance to make your voice heard in the2023 Jakarta EE Developer Surveythat is currently on-going. The survey is organized by the Jakarta EE Working Group, the body responsible for steering the development and advancement of cloud native Java development at the Eclipse Foundation.

As an independent online Jakarta EE instructor, I often get questions like...

Jakarta EE 10, the first major release of the platform since it was transferred to the Eclipse Foundation, did come with a slew of changes and updates to many of its constituent specifications. One such specification that received updates is the Jakarta Contexts and Dependency Injection specification. The specification release version for Jakarta EE 10 is Jakarta CDI 4.0, which came with major changes.

Two of such major changes are the split of the specification into a Lite and Full profiles and the change in default behaviour for an empty beans.xml file. In this blog post, we take a quick look at getting started with Jakarta CDI, in my view, the single most influential specification on the Jakarta EE Platform.
