Jakarta EE for Spring Developers

Jakarta EE 9 changed its package namespace from javax.* to jakarta.*. This may sound like a trivial change that mostly affects Jakarta EE. So, why should Spring developers care?

As it turns out, the namespace changes ripple throughout the entire Java ecosystem. And Spring is no exception. Spring Framework 6 and Spring Boot 3 raise their baseline to Jakarta EE 9 API level which is supported by Tomcat 10 and Jetty 11 for example.

Why Jakarta EE Developers are First-Class Citizens on Azure

Reza Rahman (Microsoft Corp.)

Java/Jakarta EE is an important technology to support on Azure. Enterprise Java is a heterogenous ecosystem with as much as a third of workloads still running on Java/Jakarta EE application servers such as WebLogic, WebSphere/Open Liberty, and JBoss EAP. This is particularly true for large enterprises that need to migrate their existing mission-critical, largely monolithic applications to Azure. Traditionally, Azure has not focused on strong support for such workloads but that is changing now and going forward.

Otavio Santana (Self-employed)

As software engineers, our only goal is to solve the problem in the most effective way possible. Being pragmatic and understanding the business is crucial for ensuring effectiveness in our field. DDD presents us with a potential path and strategy to follow in this sense. Although, despite its popularity, we can agree that the "blue" book is quite hard to understand and quite unclear regarding ways to put its ideas into action.

Luckily, you came to the right place!
