How to leverage the power of Jakarta EE 10 How to migrate from previous versions What to expect from Jakarta EE in the future Jakarta EE 10 is here with lots of new features and improvements. In this session, I will go through most of these features one by one with live coding examples of how to use them. As an example, you will learn how to adjust your applications to take advantage of the new CDI Lite specification in order to allow for native compilation. And how to use the brand new Java SE Bootstrapping API for Jakarta RESTful Web Services. By attending this session, you will get the full overview of what Jakarta EE 10 brings to the table, including the brand new Jakarta EE Core Profile that targets smaller runtimes. You will also get a sneak peek into what to expect beyond Jakarta EE 10.
