MicroProfile is not about annotations.
It’s about contracts.

In this hands-on guide, I build a book-catalog microservice with:
• MicroProfile Config
• Health (live + ready)
• Fault Tolerance (timeout, retry, circuit breaker)
• JWT security

All on Open Liberty.
No vendor APIs in business code.

Production behavior included. Not just “it works locally.”

AI in enterprise Java is powerful — but what about resilience & observability? #LangChain4J-CDI integrates with #MicroProfile Fault Tolerance & Telemetry out of the box. @EliteGentleman shows how to build #AI services ready for production: https://javapro.io/2026/02/25/bring-ai-into-your-jakarta-ee-apps-with-langchain4j-cdi-formerly-smallrye-llm/

Just published a new hands-on tutorial:
Reactive Messaging with Quarkus — from REST to real-time.

I walk through building a full event-driven pipeline:
➡️ open a “tap”
➡️ emit orders via REST
➡️ stream through a kitchen processor
➡️ aggregate results on completion
➡️ send final notifications

All with MicroProfile Reactive Messaging and zero external brokers.
