Jakarta EE for Spring Developers

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. Attending this session will teach you how to make this migration as smoothly as possible. A live coding demo will take you through the steps involved, and point out where to pay special attention. We will also briefly examine some of the changes introduced in **Jakarta EE 10** that will prepare you for what to expect from Spring 6.x. Some pointers to what we can expect from Jakarta EE 11 will also be given.
