title: Eclipse export file jar doesn't contain folder
body: <p>I have created a runnable jar with eclipse. Inside my project I have a folder called questionnaire which contains some text files I use. When I run my runnable jar it doesn't work except if I have in the same folder as the jar the folder questionnaire. I tried some solutions that I read in stackoverflow like add folder questionnaire as a source folder and also from properties -> java build path -> libraries ->Add class folder and add questionnaire folder but still doesn't work.</p>
  
  <p>This is the code:</p>
  
  <pre><code> File srcFolder = new File(".\\questionnaire");
   if(!srcFolder.exists()){
  
     System.out.println("Directory does not exist.");
     //just exit
     System.exit(0);
  
  }
  </code></pre>
  
  <p>And every time I get message "Directory does not exist". Also when I unzip the jar there is no folder questionnaire</p>
