Jakarta EE Core Profile and Helidon - Speed, Simplicity, and AI Integration

Jakarta EE Core Profile was introduced in Jakarta EE 10 and developed further in Jakarta EE 11. This profile enables smaller runtimes that are suitable for microservices to be certified as Jakarta EE compatible. It is also a great fit for those that want to compile their applications to native images.

Helidon from Oracle is a certified compatible implementation of Jakarta EE Core Profile. Written from scratch based on virtual threads, Helidon is simple to use, extremely fast, and well-suited for integrating AI into your applications.

In this session, I will give an introduction to Jakarta EE Core Profile with live code demos and examples using Helidon on Oracle Cloud.
