Multiple errors using javac on cmd

User_6EY7H

Dear saviours,

I'm currently trying to install an "old" plugin in ImageJ from a javascript (https://imagej.nih.gov/ij/plugins/oval-profile.html). It's not possible anymore to compile and run javascripts directly with ImagJ, so I was going to do it with the command prompt (javac).

But it returns errors such as "package package_name does not exist" and "cannot find symbol" (you'll find the screenshots bellow).

I don't understand how to solve that, because all these elements are important for the plugin to work... I would much appreciate if you could help me understand what is wrong.

Have a nice day !
