I discovered a way to fix this error:

load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'

Answer: First, make sure you've downloaded the proper version of sapjco for your system including 32 or 64-bit. Also, make sure you copy lib files to right directory that get extracted with the sapjco file.

For example on AIX: cp librfccm.o libsapjcorfc.o libsapjcorfc.so /usr/java14_64/jre/bin/

make sure permissions/owner/group are okay.
