JavaOne 2026 Session

Summary

Artificial intelligence is advancing well beyond simple chat interfaces. Modern Java applications can now incorporate Retrieval-Augmented Generation (RAG) to provide grounded, verifiable responses, and the emerging Model Context Protocol (MCP) to enable secure and controlled access to tools and data.

This session shows how generative AI can be integrated into Java systems using open-source libraries, embeddings, vector databases, and orchestration layers. We'll walk through a practical progression starting with a basic chat, extending it with RAG using domain knowledge, and finally enabling safe external actions through MCP. We'll also explore architectural patterns, integration strategies, and key considerations for performance, deployment, and safety.

Attendees will learn how to incrementally adopt AI within existing Java applications to deliver more helpful, transparent, and capable features.
