JCON EUROPE 2026: Why the Java Community Still Meets in Person

Mon, 01 Jun 2026 07:00:00 +0000

Every year, when we start planning JCON EUROPE, one question always guides us:

How do we create a conference that developers genuinely enjoy attending?

Not just another event with slides and sponsor booths. Not a place where people passively consume information and leave. We wanted to create an environment where developers actively connect, discuss, challenge ideas, and solve real-world problems together.

Looking back at JCON EUROPE 2026, I believe this spirit was visible everywhere.

Building Production-Ready AI Agents with Java and Spring AI

Thu, 30 Apr 2026 07:00:01 +0000

Java developers have been building enterprise applications for decades, but when it comes to AI, the conversation has been dominated by Python. Spring AI changes this situation. It brings the same patterns we know from Spring - dependency injection, auto-configuration, portable abstractions - to AI development.

In January 2026 we built a sample agent application, and we want to share what we learned. The sample AI agent handles conversations with memory, answers questions from internal knowledge bases, uses external APIs, and integrates with existing microservices - all running on Amazon Bedro ck. If you want to try it yourself, the Building AI Agents with Java and Spring AI workshop [1] walks you through typical challenges of Generative AI models and provides step by step solutions with code available on GitHub [2].

JCON EUROPE 2026 | April 20–23, 2026 | Cinedom Cologne

Anyone talking about modern software development today can hardly avoid Java. Few technologies have shaped the enterprise world as sustainably, and few communities are as vibrant, diverse, and innovation-driven. This is exactly where JCON comes in: as a meeting point, a platform, and an experiential space for developers from all over the world. With participants from more than 70 countries, JCON has long since become an international gathering. Openness, knowledge sharing, and a strong sense of community remain at its core.

Whose day is it on Tuesday?

I mean, Wednesday is Odin’s day, Thursday is Thor’s day, and Friday is Frigg’s day, or Freya’s, depending on who you ask. But what about Tuesday? Who is the god of Tuesday?

Odin = Wednesday Thor = Thursday Frigg = Friday

It’s Týr, the god of war and justice. In Norse mythology, Týr is known for his bravery and sacrifice, as he lost his hand to the monstrous wolf Fenrir.

How to Develop, Run and Optimize Quarkus Web Application on AWS Lambda

Tue, 05 Aug 2025 07:00:03 +0000

What will We explore and learn in this article?

In this article, we will explore some ways to develop, deploy and run applications on AWS Lambda using Quarkus framework. Of course, we will measure performance (the cold and warm start times) of the Lambda function. We will also show how we can optimise performance of Lambda functions using Lambda SnapStart (including various priming techniques) and GraalVM Native Image deployed as AWS Lambda Custom Runtime. You can find code examples for the whole series in my GitHub Account.
