Blog postI first wrote this article for the Java Advent calendar 2020. I then copied it to my own blog.
Christmas is coming! Like every year, Santa needs to schedule its presents delivery. Can you imagine? Millions of (good) children will receive a present on the night of the 24th of December. To achieve this prowess, Santa needs a bit of technical help to schedule the deliveries. What about a microservice architecture with MicroProfile and Quarkus?
Resilient Microservice Architecture -
Blog postIt’s been a while since I haven’t blogged… but that’s because I was busy writing two books on Quarkus!
When Quarkus was announced in November 2018 I was very enthusiastic with what I saw. It was the beginning of Quarkus, but it was already promoting developer’s joy (hot reload, easy configuration, etc.), Cloud-Native, speed, small… but what I liked the most was the fact that it was supporting MicroProfile and the well-known Java Enterprise ecosystem (JAX-RS, CDI, Hibernate, Bean Valid -
Blog postThis blog post follows the first one I wrote about Configuring A Quarkus Application. So, if you want to know how to configure a Quarkus application using a Unified Configuration (application.properties file), Microprofile Config or system properties, please refer to this previous post. In this blog post I will show you how to use Profiles in Quarkus.
Use Case I’ll use the same example as the previous post: we have one REST Endpoint that uses a repository to persist and retrieve books -

Blog postIn this blog post I’ll show you how to configure a Quarkus application using the specific application.properties file as well as the Microprofile Config API (check my other post for configuring with profiles). To break it into more details you will learn:
How to configure a Quarkus application and have separate values for development and test How to use Microprofile Config to inject values How to configure logging How to pass system properties Use Case In this example we have one REST -
Blog postLast year I’ve published a fascicle on Bean Validation. It was time to publish the one on JPA.
In a previous blog post I explained the entire writing process and why I had this idea of writing small fascicles. Make sure to read it if you want more details. But basically, the idea behind these fascicles comes from my previous Java EE 7 book. People were asking me to update my Java EE 7 book to Java EE 8, but I couldn’t find the motivation of updating 550 pages that were own by my edito -
Blog postJHipster is a great way to bootstrap your application. Your app can be a monolith or be split into several microservices, use JWT or OAuth2, packaged with Docker, deployed on a cloud provider… JHipster is there to handle the heavy technical complexity. Great ! But… when it comes to choosing an item from a combobox, JHipster is not that great.
In this post I will show you how to improve the generated JHipster Angular code so you can have an (optimized) auto-completion instead of just a -
Blog postWe live in a Microservices world, and this world is there to stay. Back-end developers need to dive into Domain Driven Design, write stateless, resilient, highly available services, keep data synchronized through Change Data Capture, handle network failure, deal with authentication, authorization, JWT… and expose a beautiful Hypermedia API so the front-end developers can add a great user interface to it.
Good ! But what about the front-end ?
Let’s say we have se -
Blog postFor those who follow me, you know that I wrote a few books on Java EE.
For those who follow Java EE, you know that there is a version 8 out there.
For those wondering when I’ll be updating my book to Java EE 8, I’ll say “I’ll never write again!”…. But never say never.
I’ll never write again Involved in J2EE since 1998, I followed its evolution and joined the Java EE expert group from version 6 to version 8. During that time, I wrote a book in French called “Java E -
Blog postI’ve recently posted a Tweet about my day to day life. This Tweet said “I’ve reached a point where I can test Spring code in a couple of minutes, and Java EE code in a couple of hours :o(“
I was a bit surprised to read some reactions. In fact, some people asked me to explain this Tweet a bit more… so here I am.
Who Am I? What Am I Doing? First of all, it’s important to recap who I am and where I come from. Basically, I’ve started working for BEA Systems in 1998, that’s when I -
Blog postAsciiDoc is a great way to write technical documentation. It is text based, can be committed and versionned in your VSC with your project, has a rich syntax, has a huge ecosystem, integrates with several tools (such as PlantUML that I love) and, if there is still something missing, you can use extensions or create your own. And if you use the asciidoctor-maven-plugin to automatically generate all your documentation, you end up customizing it.
In this post I explain a few configur
