ClassNotFoundException for hsqldb.jdbcDriver

Trying to set up a docker container running the mendelson AS2 server, but whenever i run I get "ClassNotFoundException for hsqldb.jdbcDriver" as an exception.
I've tried to redownload hsqldb.jar and place it inside my jlib dir, that didn't work. I've ran the command setting the classpath and confirmed that it does find the jar file, but the driver is still missing for some reason.
Running java 11.0.7 on ubuntu 18.04.

Best regards,



Turns out i was setting my PATH variable wrong, so ls was not found, hence why jlib could not be added to the class path.
