MERRY CHISTMAS AND HAPPY FALLBACK WITH MICROPROFILE

I 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 … Continue reading Merry Chistmas

TWO QUARKUS BOOKS FOR CHRISTMAS

It’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 …

WELCOME MY FASCICLE ON JPA

Last 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

JHIPSTER, ANGULAR, PRIMENG AND AUTOCOMPLETE

JHipster 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 … Continue reading

ANGULAR LIBRARIES AND MICROSERVICES

We 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 … Continue reading Angular

JAVA EE VS SPRING TESTING

CONFIGURING THE ASCIIDOCTOR MAVEN PLUGIN

AsciiDoc 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

AUTOMATING ADMINISTRATIVE TASKS WITH ITEXT AND DOCUSIGN

The one thing I hate the most is wasting time in administrative tasks. When you
have a company, deal with customers, invoice, pay taxes, sign contracts, etc.
you end up spending a lot of time doing admin instead of your real work. What do
you do? Well, you don’t have the choice. At the beginning it’s so scary, that
you print paper, sign it with … Continue reading Automating Administrative Tasks

SECURING JAX-RS ENDPOINTS WITH JWT

In this blog post I’ll show you how to use the JJWT library to issue and verify
JSon Web Tokens with JAX-RS endpoints. The idea is to allow an invocation when
no token is needed, but also, be able to reject an invocation when a JWT token
is explicitly needed. Let’s say we have a REST Endpoint with several methods:
methods that can be invoked directly, and methods that … Continue reading

The developers’ world is a mixture of evolutions and reinventing the wheel. When
I was doing EJBs 1.0 back in 1998, I was doing Micro Services. But I had to wait

O JAVA EE 7 APPLICATION SERVERS, WHERE ART THOU?

Updated Thanks for your comments. I’ve added Undertow to the test
( “Servlet-Only Distribution” on the WildFly download page), corrected some
mistakes, but more important, I’ve changed the memory benchmark: I now take a
memory usage measure at startup, I then perform GC and wait a bit for memory to
stabilize. This gives a nice min and max memory usage. Damn, I’ve been waiting
so long to … Continue reading O Java EE 7 Application Servers, Where Art Thou?

WHO CARES ABOUT TOSTRING PERFORMANCE?

Who cares about toString performance? Nobody! Except when you have huge amount
of data being processed in a batch that does plenty of logging using toString .
Then, you investigate why it’s slow, realize that the toString method is mostly
implemented using introspection and can be optimized. But first, let’s have a
look at the Javadoc to remember what a Object.toString should do: “returns a
textually representation … Continue reading Who Cares About toString
