Sealed classes are a powerful feature introduced in Java 15 that allows developers to control the inheritance hierarchy of a class. In this blog, we will explore the concept of sealed classes in the context of Jakarta EE, a set of specifications for building enterprise applications in Java.

JSON (JavaScript Object Notation) has become the de facto standard for data interchange in modern web applications. Its simplicity, readability, and compatibility have made it a popular choice for representing structured data. The JSON-P (JSON Processing) API provides a powerful and convenient way to parse, generate, transform, and query JSON data on the Jakarta EE Platform.  In this blog post, we will explore the fundamentals of the JSON-P API, its core functionalities, and how it empowers you to work with JSON effortlessly in your Jakarta EE applications. 

Apache Camel is an open source enterprise integration framework that helps you connect different systems and applications together with as little effort as possible. It provides a simple and powerful way to define and implement message-based routing and mediation rules. It is an implementation of the patterns described in the book Enterprise Integration Patterns by Gregor Hohpe and Bobby Woolf.

In simple terms, Apache Camel acts as a "translator" or "bridge" between different systems. It allows you to easily route, transform, and process messages as they move from one system to another. It supports a wide range of communication protocols and data formats (JSON, XML, YAML, etc.), making it easier to integrate different technologies and applications.

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.
