When directly unzipping the installation file for Clarity PPM 15.7, DVD0000000001001.iso, 3 install jar files are generated.
Extracting the install.jar file does not generate any files:
# jar -xvf install.jar
# ls -lta
This problem is happening if directly unzipping the .iso file, as the .jar file is too large.
Clarity PPM 15.x
This can be solved by mounting the ISO file and copying the .jar file.
