I am trying to use the rize package to create a Dockerfile for ShinyApp. Starting the rize::shiny_dockerize() comand from the App dir. One of the packages which are required is the xlsx (Probably hier it is trying also to install rJava). I get the following error:

does anyone how I can bring this to work in the rize package?
It looks like you have issues with setting proper location of Java. Note that making R happy with Java might be a little bit of struggle.
Take a look here: http://www.owsiak.org/r-java-11-and-making-sure-you-can-load-rjava/ for a sample. It is macOS based, but still, it should work fine.
Basically, what you want to do is to set your JAVA_HOME such way it points at Java installation. Once it's done, you can run R cmd javareconf like this
> sudo R CMD javareconf \
JAVA_HOME=${JAVA_HOME} \
JAVA=${JAVA_HOME}/bin/java \
JAVAC=${JAVA_HOME}/bin/javac \
JAVAH=${JAVA_HOME}/bin/javah \
JAR=${JAVA_HOME}/bin/jar
Make sure you have gcc installed and that you can compile simple C code.
