That guide isn't very clear about what those "startup scripts" actually do. They are just a shell script (which is effectively a list of programs) that has what is needed to start the server. The only reason people use them is because it means you don't have to remember all the different arguments to pass to java when it starts the server.

Are you executing the jar from the command line, or are you just clicking it in the file manager?
