From Spring Boot 2 to Spring Boot 3 with Java 21 and Jakarta EE

We are thrilled to announce our next Ottawa Java User Group event, and it promises to be an absolute treat for all Java aficionados. Our distinguished guest speaker for this event is none other than Java Champion Ivar Grimstad, renowned Jakarta EE Developer Advocate at the Eclipse Foundation.

Mark your calendars and join us for an engaging session where Ivar will share his deep insights into the world of Spring Boot and Jakarta EE. This is an opportunity you won't want to miss!

Abstract: 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 raised 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 smooth 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 planned for Jakarta EE 11 that will prepare you for what to expect in future versions of Spring.
