  • Monitoring Java Virtual Threads

    Introduction In my previous article, we’ve seen what Virtual Threads (VTs) are, how they differ from Platform Threads (PTs), and how to use them with Helidon 4. In simple terms, VTs bring in a new concurrency model. Instead of using many PTs that can get blocked, we use a few of them that hardly ever…

  • Secure your JAX-RS APIs with MicroProfile JWT

    In this article, I want to illustrate in a practical way how to secure your JAX-RS APIs with MicroProfile JWT (JSON Web Token). It is illustrated by a GitHub project using Quarkus, Wildfly, Open Liberty and JWTenizr. A basic knowledge of MP JWT is needed and, if you don’t feel comfortable with that, I invite…

  • Optimize your code for Quarkus

    My previous article, was about running a JakartaEE/MicroProfile application with minimum changes. My purpose was to keep the Java code as standard as possible so that it can keep running on other implementations such as OpenLiberty, Payara, KumuluzEE, TomEE. This article proposes an alternative: how to optimize your code for Quarkus? It turns out that…

This is a preliminary work for the MicroProfile GraphQL initiative that has just…

It defines a set of APIs to interact with NoSQL databases and provides a standard implementation for most NoSQL databases.” The ambition of JNoSQL is to provide a consistent developer experience…

  • When GraphQL meets MicroProfile

    After a year of actively observing the transition from Java EE to Jakarta EE (including several conferences I have given on the subject), I’ve decided to get more concretely involved in 2019. I’ve taken the opportunity to participate to the MicroProfile GraphQL initiative. In this blog post I’m going to explain how the group started, what…

  • About “Java EE 8 High Performance” by Romain Manni-Bucau

      First off, I must say that my opinion on this book might be a little biased. Indeed, the author Romain Manni -Bucau had worked for several years in my team at Atos Worldline. I’ve known him first as an intern and have been impressed by his capacity to deep dive and quickly into technical…

Motivations According to David Delabassee, Oracle Java EE evangelist, the motivations leading to this decision are to make Java EE more…
