body: <p>I want to run a particular class in Ecplise called 'RunCreateNetwork'.</p>
  
  <p><img src="https://i.stack.imgur.com/f61Ve.png" alt="enter image description here"></p>
  
  <p>However, when I choose <em>Run as</em> and create new Application Config, it doesn't allow me to choose project, where this class is located.</p>

  <p>Give me an advice how to run it, if you can, please.</p>
