title: How to copy file inside jar to outside the jar?
body: <p>I want to copy a file from a jar. The file that I am copying is going to be copied outside the working directory. I have done some tests and all methods I try end up with 0 byte files.</p>
  
  <p><strong>EDIT</strong>: I want the copying of the file to be done via a program, not manually.</p>
