This is a bit of a different type of post… At my son’s school, the piano in the music class had a few issues, and I went “on a quest” to fix it :-) This post is a collection of what info I needed to get this done, written down here, just in case someone is looking for the same info.

For the second video in this “JFX In Action” series, I talked to Daniel Zimmermann. He got my attention when he recently tweeted: “To your dismay I have to tell you I write all my desktop applications using Kotlin and JavaFX”. Why is he a big Kotlin AND JavaFX fan? I asked him and got a demo of the network test application that he is working on.

People who follow me, know I have a big love for JavaFX. It’s my go-to for every desktop user interface application I build. I love the simplicity of quickly creating an app that makes full use of the “Java powers” to build both multi-threaded “backend services” combined with a beautiful-looking UI into one executable. I’m starting a new video series “JFX In Action” in which I talk to developers to show the world what is being developed with JavaFX, starting with Pedro Duque Vieira about the JavaFX libraries and apps he creates.

For a personal pet project, I started experimenting with JavaFX and Kotlin to create a user interface with a lot of Java / Kotlin background processing. As I knew there is a book available on this specific topic, Apress was so kind to send me a review copy of Frontend Development with JavaFX and Kotlin: Build State-of-the-Art Kotlin GUI Applications by Peter Späth (152 pages, 48€ on paper, 35.5€ for ebook on Amazon.nl).

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…

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.

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.
