Jakarta Tech Talks

Join Igor as he demonstrates how to install lightweight servlet containers such as WildFly, TomEE, GlassFish, Payara, Open Liberty, or Tomcat on a Raspberry Pi. This session will provide practical insights for Java developers and hobbyists looking to experiment with microservices and small-scale Java applications on low-cost hardware.

## Jakarta Tech Talk - Jakarta EE 12: Entering the Data Age of Enterprise Java

Jakarta EE 12 marks a fundamental shift in how enterprise Java treats data, lifecycle, and configuration at the platform level. This release introduces the Data Age of Jakarta EE, where querying, data access, initialization, and consistency are treated as first-class concerns across the entire ecosystem.

In this session, we explore what’s new in Jakarta EE 12, focusing on Jakarta Query as a unifying query language across Jakarta Persistence, Jakarta Data, and Jakarta NoSQL, and how this foundation reshapes higher-level specifications. We examine how CDI evolves beyond lazy dependency injection to support eager initialization and predictable startup behavior—an essential requirement for data-driven systems, cloud-native runtimes, and agent-based architectures.

We also discuss the impact of Java 21 as the new platform baseline, the growing role of polyglot persistence, and emerging initiatives such as Jakarta Agentic AI. Rather than viewing specifications in isolation, this talk connects them into a coherent platform story, showing how Jakarta EE 12 reduces fragmentation, improves developer productivity, and enables architects to design adaptive, long-lived enterprise systems without breaking existing applications.

# Jakarta Tech Talk: A JUG-gle is Real - Growing Java Communities: Challenges, Shifts & Opportunities

Building and sustaining vibrant Java communities is both rewarding and challenging. Based on insights gathered from various JUG leaders and long-time community members, this talk explores the real-world challenges many Java communities face: from geographical limitations and localization challenges, to engaging younger audiences and collaborating with universities.

We’ll reflect on how the global pandemic reshaped the Java community event formats - forcing to adapt to virtual and hybrid models - and the lasting impact these shifts have had.

We’ll discuss why continuity and consistency are critical to long-term success, and how strong, people-driven leadership - often from passionate Java experts and enthusiasts - keeps these communities alive and thriving. At the heart of every successful JUG is a team of committed individuals who create meaningful connections, foster technical growth, and build spaces where others want to contribute.

This talk shares practical strategies, stories, and inspiration for anyone working to grow or support a Java community.
