Sessions

Session Title: Java meets AI: Build LLM-Powered Apps with LangChain4j
Speaker(s): Eric Deandrea & Jan Martiska
Day/Time: To be determined...
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.

Session Title: Quarkus for Spring Developers
Speaker(s): Eric Deandrea
Day/Time: To be determined...
Abstract: In this session, I will show concepts and conventions familiar to Spring developers and how those same concepts and conventions can be implemented in Quarkus, all while highlighting similarities and differences between them. Additionally, I will show similarities and differences in how testing is done, highlighting Quarkus Dev Services.

This session will be mostly live coding while minimizing the amount of slides. I will introduce an existing Spring application with a full test suite and build a Quarkus equivalent version of it, live.
