title: Classpath resource within jar
body: <p>I have a project A, which contains some java files and a classpath resource R.txt. Within the project I use ClassLoader.getSystemResource("R.txt"); to retrieve R.txt. </p>
  
  <p>Then I have a project B which includes project A's jar-file. Now getSystemResource("R.txt") wont find the textfile (and yes, it's still in the root of the jar file). Even trying "/R.txt" as was suggested on some other site didn't work. Any ideas? </p>
