The Past, Present, and Future of Enterprise Java

Over the last 30 years, Java has been the preferred technology for developing enterprise applications. Frameworks and approaches such as J2EE, Spring Framework, Java EE, Spring Boot, and Jakarta EE all contribute to this success story.

This session will give you a history lesson of Enterprise Java and an overview of Jakarta EE 11 with lots of code demos. We will also look forward and check out what's in the pipeline for Jakarta EE 12.
