Sessions

Building Intelligent Java Apps: Agent Patterns, MCP, and the Future of AI Native Design [LRN1011]
Speaker(s): Daniel Oh
Date/Time: TBD
Abstract: 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 multiagent 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.

Java at Nation Scale: Processing 8 Billion Monthly Transactions at CAIXA [LRN1446]
Speaker(s): Nilson Junior
Date/Time:
**Abstract:**Caixa Econômica Federal (CAIXA) is not just a bank; it is the financial backbone of Brazil, serving over 150 million citizens. Operating at a staggering volume of 8 billion transactions per month, CAIXA faces engineering challenges that demand extreme resilience and massive concurrency. This session reveals how CAIXA leverages a robust architecture to sustain this hyperscale operation. Attendees will explore the bank's journey from monolithic systems to a modern ecosystem where Java microservices (Spring Boot and Quarkus) orchestrate complex interactions between digital channels and core ledgers. We will discuss the strategic partnership with Oracle, utilizing Exadata Cloud@Customer to ensure the high-performance data persistence required by the instant payment system, which alone processes over 40 million daily operations. Learn the architectural patterns used to handle traffic spikes during national social benefit payouts. We will dissect how the synergy between Java's agility and Oracle's robust infrastructure empowers CAIXA to bridge the gap between legacy reliability and cloud-native innovation.
