R loading rJava error

Question

I am running R (version 3.4.0) on macOS sierra (10.12.5), and I am trying to use the xlsx library, which requires the use of the rJava library.

When I try to load rJava using library(rJava)in the R console (no difference if in RStudio or in the terminal), I get the following error message that I am having problems with:

Fehler: package or namespace load failed for ‘rJava’:
 .onLoad in loadNamespace() für 'rJava' fehlgeschlagen, Details:
  Aufruf: dyn.load(file, DLLpath = DLLpath, ...)
  Fehler: kann shared object '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so' nicht laden:
  dlopen(/Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so, 6): Library not loaded: @rpath/libjvm.dylib
  Referenced from: /Library/Frameworks/R.framework/Versions/3.4/Resources/library/rJava/libs/rJava.so
  Reason: image not found

Inclusion of the problem I found several posts on several similar ones (but each time a little different problems), this SO question was the most promising among them.

Since the steps proposed require adaptation to my business, and I'm kind of a beginner, I could not implement them. What can I do?

Additional Information:

The shell command java -versionreturns:
