Session Abstracts

19:00 Get Ready for Jakarta EE 10! Jakarta EE 9 lowered the barriers of entry and established a foundation for future innovation paving the way for Jakarta EE 10.

With Jakarta EE 10, we introduced Jakarta EE Core Profile which targets smaller runtimes suitable for microservices. The Jakarta EE Core Profile also aims to be an even better fit for compiling to native images. But it does not stop there. Both Jakarta EE Web Profile and Jakarta EE Platform is moving forward as well with updates to almost all the individual specifications.

Join this session for the latest updates on the progress with Jakarta EE 10. I will go through what Jakarta EE 10 brings to the table, and what to expect when the specifications are moving forward. The session will also give you a clear understanding of how to migrate from previous versions of Jakarta EE and Java EE as well as show how to leverage Java SE 17 and newer features with Jakarta EE.

20:15 Jakarta MVC 2.0 - The Good Parts! Server Side Rendering seems to be getting a revival this year, so maybe it is time to take a look at Jakarta MVC again?

Jakarta MVC 2.0 was released in December 2020 and supports the jakarta.* namespace introduced in Jakarta EE 9. In this demo-driven session, we will explore the features of Jakarta MVC in practice. You will learn how to implement the models, views, and controllers of a Jakarta MVC application. We will also see in practice how Jakarta MVC supports data binding, security, internationalization and observability. To spice it up, we will play around with the wide range of view engines supported by Eclipse Krazo.

About Ivar Ivar is the Jakarta EE Developer Advocate at Eclipse Foundation. He is a Java Champion and JUG Leader based in Sweden.

Besides advocating the Jakarta EE technologies, Ivar is contributing to the Jakarta EE specifications as well as being the PMC Lead for Eclipse Enterprise for Java (EE4J). He is also one of the specification leads for Jakarta MVC and represents Eclipse Foundation in the JCP Executive Committee.

Ivar is also involved in MicroProfile, Apache NetBeans, and a wide range of other open-source projects and communities. He is a frequent speaker at International developer conferences.
