Sessions

Session: Practical MCP Security in Action
Speaker(s): Willem Jan Glerum
Date/Time: Wednesday, June 3rd at 10:00 - 10:50
Abstract: AI Assistants need to securely authorize and access Model Context Protocol (MCP) servers to safely use imported tools, prompts and resources. In this session, we will discuss what it takes to create a secure MCP server, explain how MCP Authorization works, and cover important security considerations. We'll demonstrate how an MCP client running as a Single Page Application can seamlessly use OAuth2 authorization code flow and dynamic client registration to import and access MCP servers securely. We will also look at how MCP Clients can run in scope of a larger enterprise AI application and propagate user authentication tokens to secured MCP servers. Throughout the session, we will work with popular MCP clients as well as the Quarkus MCP Server and Client. No prior experience of Quarkus is required.

Session: Agentic AI Patterns for Enterprise Software
Speaker(s): Kevin Dubois
Date/Time: Wednesday, June 3rd at 11:05 - 11:55
Abstract: Developing AI applications today isn’t just about experimental single-model interactions. Organizations are rapidly adopting AI and to do that, the requirements for enterprise software become increasingly more complex. Advanced Agentic AI systems address this need, where multiple specialized agents work together, each capable of independent reasoning. The real challenge for architects lies in orchestrating these agents to collaborate effectively towards a common goal. Unfortunately though, "one-size-fits-all" or “off-the-shelf” approaches to coordination just don't work due to the complex nature of software. In this session we'll explore the spectrum of agentic patterns, from reliable and predictable, but rigid workflows to highly flexible, autonomous agent orchestration using LLMs, and everything in between. This talk will cover: * The pros and cons of various agentic patterns. * Practical demonstrations of how to combine these patterns in an enterprise software environment with Java, LangChain4j and its Quarkus extension. * How to leverage the provided infrastructure for agent collaboration. * The flexibility to implement and seamlessly integrate your own custom agentic patterns.

Session: Concurrency Crossroads: Choosing between Reactive Programming and Virtual Threads in Quarkus
Speaker(s): Willem Jan Glerum
Date/Time: Wednesday, June 3rd at 15:20 - 17:15
Abstract: Reactive programming has been the way to go for extra performance and concurrent programming, now we also have Virtual Threads (Project Loom). Which one should we choose? Can we leverage both? What's the best approach to write high-performance non-blocking code in our application? In this talk we'll explain the background behind both paradigms and go over the details together. We will cover the advantages and disadvantages of both paradigms using real-world examples in Quarkus. Furthermore, we will tell you the gotchas so you don't have to discover them yourself and we will also look ahead at what's coming next in future Java versions. We will aim to make this talk as simple as possible and show real code combined with live coding. After this talk you will understand both paradigms and be able to choose the right approach for your next project.
