The Jakarta EE Working Group surveyed over 170 developers between July and August 2024, revealing that Jakarta EE 8/Java EE 8 remain dominant, Java SE 17 is the most used version, Spring Boot and Tomcat lead runtime adoption, and MicroProfile adoption is split between newer and legacy versions.
This article explains the MicroProfile OpenAPI 3.0 specification, covering its architecture, configuration options, core properties, annotation usage, server definitions, programming model, model readers, filters, processing rules, endpoint behavior, and release notes for both 3.0 and earlier versions.
This article explains why cloud‑native microservices are beneficial, defines their key characteristics, and provides a detailed, side‑by‑side comparison of MicroProfile and Spring frameworks—including REST APIs, dependency injection, configuration, fault tolerance, security, health checks, metrics, and tracing—along with concrete code examples and starter resources.
This article explains why cloud‑native microservices are beneficial, defines their key characteristics, compares the MicroProfile and Spring frameworks, and provides detailed code examples for REST APIs, configuration, fault tolerance, security, health checks, metrics, and distributed tracing to help developers select the most suitable technology stack.
The whitepaper outlines Jakarta EE's strategic importance, citing adoption surveys, open‑source benefits, deep ecosystem integration, stability, flexibility for cloud‑native and monolithic architectures, and a vibrant community that together make it a compelling platform for today’s and future Java development.
Jakarta EE, the rebranded successor to Java EE, has renamed each specification to clarify its future role, switched from the javax to jakarta namespace, and introduced consistent naming, affecting developers who must adjust dependencies and consider compatibility with servers and frameworks like MicroProfile and Quarkus.
This tutorial walks through creating a lightweight RESTful web API for managing people using Java EE standards such as JAX‑RS, CDI, JPA, Bean Validation, OpenAPI, and the Eclipse MicroProfile stack, showing the full code, Maven setup, and integration testing.
Since its transfer to the Eclipse Foundation, Java EE is undergoing major shifts—including an open‑source compatibility kit, a push for cloud and microservice features, the EE4J charter for more flexible governance, and Oracle’s contribution of GlassFish—signaling a new era for enterprise Java development.
