Hanno Embregts will talk about ‘From Zero to Secured: Live-Coding a Full-Stack Jakarta EE REST App with MicroProfile and JWT AuthenticationPermalink’.

Join Hanno for a comprehensive session designed to take you through building a secure, full-stack Jakarta EE application from scratch! Over the past year, he has taught a group of junior developers the intricacies of Java and Jakarta EE, and they happened to encounter various challenges in securing a REST application with JWT and connecting it to a frontend. Let’s address these challenges together during this talk by:

Live-coding a RESTful app from scratch using the latest versions of JAX-RS, JPA, and MicroProfile.
Implementing JWT-based authentication.
Documenting REST endpoints with OpenAPI.
Connecting an Angular frontend to the REST app.

Along the way, you’ll hear about key concepts like stateless EJBs, dependency injection, JPA basics, DTOs, password encryption, and JWT structure & verification. Not the biggest fan of theory? Don’t worry – Hanno will include as much live-coding as possible, which makes this talk perfect for developers who want to master practical Jakarta EE application development and security.
