Modernizing Java EE Monoliths: A Roadmap to Scalable Microservices

Ondro Mihalyi

Abstract:
Legacy Java EE monoliths still power many critical systems, but scaling and evolving them for the cloud can be a major challenge. In this session, I’ll share a practical, step-by-step approach to modernizing monolithic applications into scalable microservices using Jakarta EE, MicroProfile, and cloud-native tools—based on real-life experience from a recent client project undergoing this exact transformation.

We’ll cover how to identify service boundaries, isolate functionality using the strangler pattern, and incrementally transition to microservices without disrupting business operations. You'll see how to improve communication using REST and messaging platforms like Kafka, while applying MicroProfile APIs for configuration, health checks, metrics, and resilience.

We’ll also explore cloud deployment strategies and maintenance in production, including monitoring and troubleshooting.

Whether you’re starting your modernization journey or refining your approach, this talk provides a proven, experience-backed roadmap you can apply in your own projects.

Teaching AI Agents to Write Better Tech Docs

Dmytro Patserkovskyi

AI agents are evolving rapidly and have become part of our day-to-day work. They write code, run builds, and, since they generate human-like text, are particularly well-suited for writing technical documentation... right?
In this presentation, we'll take a step back and revisit what makes technical documentation truly effective. We'll explore how to leverage skills to guide AI agents toward producing higher-quality documentation.

Engineering a Simpler Java Build Tool

Haoyi Li

Ort: Hotel Eden-Wolff, Arnulfstraße 4, 80335 München

The Java language is known to be performant, easy to use, and with great IDE support, but build tools like Maven or Gradle do not always live up to that reputation. This talk will explore why build tooling is fundamentally such a difficult domain to work in, but also how there is a lot of low-hanging fruit to improve upon the tools available in the Java ecosystem. We will end with a demonstration of a new Java build tool "Mill" that makes use of these ideas, proving out the idea that Java build tooling has the potential to be much faster, safer, and easier to use than it is today.
