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.”

Dive into the latest advancements in #Java with our latest article on JDK 21's virtual threads: https://bit.ly/4cEppIA

This analysis compares the performance of virtual threads with Open Liberty's thread pool, focusing on key findings such as throughput, ramp-up times, and memory footprint. While virtual threads offer several advantages, they also show unexpected performance issues, especially in CPU-intensive workloads.

This analysis guides Java developers on when and how to use virtual threads in their applications.

Нереальная локализация

Давно хотелось раскрыть интересную тему локализации ПО, но так чтобы не повторяться и не цитировать прописные истины. Поэтому рассказываю как локализовать обычное корпоративное Java-приложение на.. несуществующие фантастические языки : Клингонский и Р’льех . Погрузиться
