Description

# Jakarta EE on Virtual Threads: How Helidon MP 4.3 Delivers Reactive Performance with Blocking Code. 

For years, enterprise Java developers faced a difficult trade-off: stick to the familiar, simple blocking style of Jakarta EE (JAX-RS, CDI) or switch to complex reactive paradigms to achieve high-throughput concurrency.
Helidon MP 4.3 shatters this dilemma.
Built on the revolutionary Helidon WebServer, Helidon 4 is the world’s first microservices framework designed from the ground up for Java 21 Virtual Threads. This architecture allows you to write standard, imperative MicroProfile code that automatically benefits from massive scalability—no CompletableFutures or reactive chains required.

In this session, we will explore how Helidon MP 4.3 combines the stability of Jakarta standards with the cutting edge of Java development. We will dive into a live coding demonstration showcasing:

• The Virtual Thread Advantage: How Helidon achieves "reactive" performance with blocking APIs, and why this matters for your architecture.
• Helidon AI Integration: A look at the new LangChain4j support, enabling you to inject LLM capabilities directly into your microservices using declarative annotations.
• Productivity Boosters: A walkthrough of the Helidon Data Repository pattern, significantly reducing boilerplate code for JPA/persistence operations.

Join us to see how Helidon MP 4.3 allows you to build the fastest, most modern microservices using the Jakarta EE skills you already possess.
