About us
This is the Java User Group for everyone interested in Java, JVM, Web Development, Free and Open Source Software who are located in Amsterdam or Netherlands.
The "official language" is English, so that non-Dutch speakers can also participate easily.
Looking forward to meeting you all and exchange of knowledge and ideas.

Amsterdam JUG Workshop: Spec-Driven Development with AI Agents
Gj IT, Rapenburg 58/2, Amsterdam, NLAI coding agents can write code fast, but speed without structure is just chaos at scale. This hands on workshop (bring your own laptop) gives you a framework that makes AI a reliable, auditable partner: Spec-Driven Development (SDD).
Anton Arhipov, Java Champion and much more (see bio below) is available at short notice for this free 2 1/2 hour workshop in a friendly informal environment (with free lunch and drinks). Join in and learn to lead an AI agent from high-level requirements through a detailed plan, a task list, and all the way to working software, step by step, with you in control at every stage.
The session is built around a single evolving application:
- We'll start with a batch application that imports CSV data into a database - simple enough to understand end-to-end, complex enough to feel real.
- Next, we will add more functionality by turning the batch application into a Spring Boot web service.
- To have more fun, we'll build a web UI to visualize the data.
While the agent does most of the work for writing code, we will review and discuss the results.
What you'll take away:
- A practical SDD workflow you can apply on your next project — with or without the exact tools shown.
- Hands-on experience directing an AI agent in IntelliJ IDEA through structured artifacts.
- The confidence to add AI to your process without losing ownership of your codebase.
Limited seats available (super exclusive to 40, maximum).
About Anton Arhipov. Anton is a Developer Advocate at JetBrains, where he focuses on IntelliJ IDEA and the intersection of AI agents and developer tooling. A Java Champion since 2014 with a background in server-side development, he has spent over a decade building tools and content for developers. These days, you'll find him speaking at conferences, exploring agentic workflows, and looking for ways to make the development experience smarter and more enjoyable.

Amsterdam JUG Meetup at Backbase
Backbase, Oosterdoksstraat 114, Amsterdam, NLJoin in with the latest Amsterdam JUG Meetup at Backbase, Oosterdoksstraat 114, 1011 DK Amsterdam.
In this unique Amsterdam JUG meetup, hosted at Backbase, and run by the Amsterdam JUG together with Steve Poole, Java Champion and Developer Relations Lead at HeroDevs, we'll be discussing the theme of the moment with a panel of technology leaders (such as Daniel Gebler, Picnic CTO): "Did AI Just Break Software Security Forever?"
Agenda
17:30 - Doors Open (And Food!)
18:00 - 19:00 Panel Discussion 1
19:00 - 19:30 Break

If you’ve kept your eye on AI in the news this year, and who hasn’t, you’ll have heard all about Mythos, the short lived ban on Anthropic’s Fable frontier model and maybe even the recent US Whitehouse Gold Eagle initiative.
If you missed any of this, and even if you didn’t you may have missed the frighteningly real emerging situation: we’ve crossed a threshold into a new world where software vulnerability detection and exploitation are beginning to outstrip human abilities to respond.
In this panel discussion, we’ll explore what’s been happening, where it might all be going, and most importantly what does it mean for Java developers.
We’ll look at tools you can use, the rise of open-source clearing houses, the consequences of legislation, organizations to follow and ways to get ahead of what might just be the world of tomorrow.
