B4J Question Liberica 11.0.11 full JDK install problem in Raspberry Pi 4b

[hatzisn]

Good evening everyone,

I tried to install Liberica 11 from their site (I also tried with 16) in Raspberry Pi 4b. I have read that the full JDK includes the JavaFX too to run UI applications in Raspberry Pi.
I failed big time. I followed the installation instructions as described here:

Raspberry Pi B4J UI Applications with Liberica JDK

Tutorial Raspberry Pi B4J UI Applications with Liberica JDK v20180513 Objectives To build B4J UI applications, using the Liberica JDK10, running on the Raspberry Pi. This tutorial covers setup of the Raspberry Pi, Liberica, development hints and few sample applications. NOTE 20190406 Since...

And here is what I get

pi@raspberrypi:~/Downloads $ sudo apt install ./bellsoft-jdk16.0.1+9-linux-aarch64-full.deb

Why is this happening (changing what to install)?

Edit - the code is from when I tried to install the Java 16.0.1 full JDK but failed with the same errors

Here is how we do it (using RPI 4B):

1. We download JDK 11 32 bit for Linux ARM (in tar.gz format) from:

Java Download | Java 8, Java 11, Java 17, Java 21, Java 22 - OpenJDK Builds for Linux, Windows & macOS

Download Liberica JDK, supported OpenJDK builds. Open source Java 8, 11 and more for Linux, Windows, macOS.

bell-sw.com

Looks like this (scroll down - make sure to get 32 bit version):

2. Make sure to copy the downloaded tar.gz file to the /home/pi folder.

3. Now use the commands below (this example being for 11.0.10 - change as needed):

From the terminal:
• sudo mkdir /usr/java
• sudo cp bellsoft-jdk11.0.10+9-linux-arm32-vfp-hflt-full.tar.gz /usr/java
• cd /usr/java
• sudo tar -xf ~/bellsoft-jdk11.0.10+9-linux-arm32-vfp-hflt-full.tar.gz
• sudo update-alternatives --install /usr/bin/java java /usr/java/jdk-11.0.10-full/bin/java 1000
• sudo update-alternatives --install /usr/bin/javac javac /usr/java/jdk-11.0.10-full/bin/javac 1000

To check java is installed type following (from the terminal)
• java -version
• javac -version

JFX ships with Bellsoft java version 11 so DONT install open jfx.

Reboot system.

Hope this helps.

Thanks a lot. It works now. If someone has already installed the OpenJDK 11 they need also the following steps:
• sudo update-alternatives --config java (and then select the appropriate)
• sudo update-alternatives --config javac (and then select the appropriate)
