Abstracts

Building Intelligent Java Apps: Agent Patterns, MCP, and the Future of AI Native Design - Daniel Oh (IBM)

As AI rapidly evolves from model experimentation to production-grade applications, Java developers are increasingly faced with a new paradigm: designing intelligent systems that can reason, interact, and adapt.

This talk explores the emerging Java AI application development journey through the lens of agent-based architecture, with a focus on how the Model Context Protocol (MCP) and Agent2Agent (A2A) communication patterns are transforming the way we build intelligent, context-aware services.

We’ll walk through the foundational shifts in building AI-native Java applications—moving beyond single-shot prompt-response interactions to multi-agent coordination, persistent memory, and tool-augmented reasoning. We’ll also address the critical architectural trade-offs: performance versus flexibility, open source versus vendor-managed inference, local versus remote model deployment, and how to maintain security and observability in agent-based systems.

The Mainframe, Java, and the Database - Jeroen Dijkmeijer (SVB) and Danny Calame (SVB)

Details coming soon.

Crafting the Ultimate Docker Image for Spring Applications - Pasha Finkelsteyn (BellSoft)

Docker is the cornerstone of today's development! Let's overview quickly how we use it in JVM development and then transition to practical examples.

We will start with a simple Docker image containing a popular "one fat JAR" and look into its downsides (deployment speed, traffic volume). To address them, we will discuss the strategy of splitting the JAR into multiple layers and using multistage Dockerfiles, gradually improving our image.

Join me to learn how to build the ultimate Docker image for Spring applications.

MCP Apps with Spring AI - Alexey Lihovodov (Indurex)

MCP is already the de facto standard for connecting LLMs to tools and data, and earlier this year MCP Apps shipped as an official extension. Tools can now return interactive UI components that the host renders
directly in the conversation, and a single MCP server can light these up across multiple hosts without per-client
code.

This talk unpacks how MCP Apps fit into the wider MCP picture, and walks through building one with Spring AI. We'll also cover the rough edges, since first-class MCP Apps helpers aren't in the framework yet.
