A Developer's Guide to JakartaEE 11 with Michael Redlich
In his Devnexus presentation, Michael Redlich provides a comprehensive look at Jakarta EE 11, the latest evolution of the platform formerly known as Java EE. He begins with a brief history, tracing Jakarta EE from its origins in the late 1990s through its donation to the Eclipse Foundation and subsequent rebranding. Redlich emphasizes the platform’s flexibility, offering multiple profiles for different development needs: the full Platform Profile, the Web Profile for web-focused applications, and the Core Profile, a streamlined subset designed specifically for microservices and cloud-native runtimes.
The talk dives into the key updates and features that make Jakarta EE 11 a modern choice for developers. Notable additions include the Jakarta Data specification, which simplifies database access, and support for Java records integrated across specifications like Expression Language and Jakarta Persistence. Performance enhancements include the use of virtual threads from JDK 21 within Jakarta Concurrency, enabling scalable, concurrent applications with minimal code changes. Security is also improved with the new JWT Bridge, while deprecated features such as the security manager are removed to streamline development.
Redlich rounds out the presentation with a practical demonstration of a “beer database” application, showing how Jakarta Data works seamlessly with MongoDB to simplify data access without complex configuration. He also highlights other updates, such as replacing legacy java.util.Date with the modern Java Time API and validating records with Jakarta Validation. The talk makes it clear that Jakarta EE 11 is actively modernizing, providing developers with a simplified, powerful foundation for building scalable, cloud-native Java applications.
