Example Java Application with Embedded Jetty and a htmx Website
I was experimenting with a Java application that can act as a web server and includes the user interface HTML-files that get modified with htmx, to replace certain parts of the HTML with other ones created in Java. I found it pretty hard to understand how to configure the embedded Jetty webserver, but as always with Java libraries, it’s pretty easy once you understand how to do it ;-) I decided to share my example, so you don’t need to go through the same search if you want to use the same approach…
Review of the Elecrow Raspberry Pi Pico Advanced Kit
People who follow me, know I’m a big fan of the Elecrow CrowPi, the little suitcase with a Raspberry Pi and a lot of electronic components included. I used it already a lot in my presentations at various conferences to demonstrate #JavaOnRaspberryPi.
Search in Documentation with a JavaFX ChatGPT-like LangChain4j Application
At the Fosdem conference in Brussels on February 3rd, I gave a presentation about using an existing documentation set as the data for a ChatGPT-like application, created with JavaFX and LangChain4J. The video and links of that presentation are available here, and this post is a more detailed explanation of that application.

Interviews at the J-Fall 2023 Conference
I had a lot of interesting talks with Java experts since I started producing the Foojay Podcast. But when I asked the organizers of the J-Fall conference, if I could do some kind of live broadcast at their event, I hadn’t imagined it would be such an amazing experience! During the day I had 29 interviews, which I all broadcasted live on multiple websites (YouTube, LinkedIn, and Twitter) with the amazing restream system.
A JavaFX Game Application in a Single Java File with JBang and FXGL
FXGL is a framework to easily create JavaFX-based game applications. In this blog post, I want to show you how this can be done within a single Java-file which doesn’t need a full Maven or Gradle project but can be executed directly with JBang without compilation. This approach can be used as an easy way to get new Java(FX) developers started or create your first experiments with FXGL.
