Java meets AI: Build LLM-Powered Apps with LangChain4j
Speaker(s): Georgios Andrianakis & Lize Raes
Day/Time: TBD
Abstract: Join us for a guided tour through the possibilities of the LangChain4j framework! Chat with virtually any LLM provider (OpenAI, Gemini, HuggingFace, Azure, AWS, ...)? Generate AI images straight from your Java application with Dall-E and Gemini? Have LLMs return POJOs? Interact with local models on your machine? LangChain4j makes it a piece of cake! We will explain the fundamental building blocks of LLM-powered applications, show you how to chain them together into AI Services, and how to interact with your knowledge base using advanced RAG.
Then, we take a deeper dive into the Quarkus LangChain4j integration. We'll show how little code is needed when using Quarkus, how live reload makes experimenting with prompts a breeze and finally we'll look at its native image generation capabilities, aiming to get your AI-powered app deployment-ready in no time. By the end of this session, you will have all the technical knowledge to get your hands dirty, along with plenty of inspiration for designing the apps of the future.

Why You Should Use Quarkus For Your Next Project
Speaker(s): Sebastian Daschner
Day/Time: TBD
Abstract: In this session, we'll have a look why you want to try out "supersonic, subatomic Java" with Quarkus. If you're familiar with enterprise development with Spring or Java/Jakarta EE, you'll be delighted to see the effective way of working that Quarkus provides. We'll why coding with Quarkus not only makes our work more effective but is also fun. We will have a look at the coding experience, turnaround times, Quarkus' dev mode, container & Kubernetes support, persistence, and templating. Join us for this live-coding-only session!

Is Loom really the future of enterprise Java?
Speaker(s): Martin Štefanko
Day/Time: TBD
Abstract: Project Loom, or virtual threads, promised fast, lightweight user-space threads that are very cheap to block. While this is true, everything in life comes at a price. Virtual threads allow users to not care about it. It is the job of the underlying libraries that all our applications use. Issues that can still occur with virtual threads, such as pinning, monopolization, or large thread-local objects, still present real-world problems many libraries still need to account for. Especially in enterprises, these issues might only be noticed once the system reaches the peak loads, which is usually too late. In this session, we explain the virtual thread model execution and compare it to the event loop/reactive model utilized in Quarkus. We will also dive into individual problems that virtual threads might encounter and demonstrate how you can verify that your code doesn’t run into them. By the end of the talk, you’ll understand these (from the user point of view invisible) potential issues with Project Loom.
