Foreword
Businesses do not care about microservices, twelve-factor apps, or cloud native Java. They care about delivering business value to their customers, open and community-driven APIs, and runtime portability.
With a great developer experience comes increased productivity with “to the point” code—meaning high maintainability. The less code you have to write, the easier it is to spot bugs and implement new functionality. J2EE was designed as a “micro cloud” to host multiple, isolated applications. The EJB programming restrictions discouraged you from accessing the local filesystem, loading classes dynamically, or changing your isolated environment in any way. These formally unpopular, but now obligatory, programming restrictions are older than J2EE (EJBs came first) and are still a good idea today.
Java EE 5 greatly simplified the programming model, servers became leaner, and the transition from shared application servers to single microservice runtimes began. Between Java EE 5 and Java EE 8 the platform was extended with internet-related APIs for REST support, JSON, WebSockets, and asynchronous behavior out of the box. The build is as simple as the programming model is. All the Java EE APIs are bundled as a single, “provided” dependency in Maven’s pom.xml. Java EE/Jakarta EE is mature, stable, and therefore a genuinely boring runtime. Most Java EE APIs are iteratively refined for years, so expect no revolution. This is great news for businesses and pragmatic developers: demand ...
