Hi, I need to run a jar file on Big Sur that runs fine on Catalina. Not only can't I run it, but when I back up and just try to compile and run a simple HelloWorld I can't do that on Big Sur either. I have installed java but when I enter javac HelloWorld.java on Big Sur I get a file not found. I've also tried entering the entire path to the file and that doesn't work either. On Catalina, the first time I tried this in a new file I got a pop-up that asks me for permission and then it works fine so my assumption is that this is a permissions issue. Any thoughts? Thanks, Daniel
