title: Debug Javascript within Eclipse using Rhino
body: <p>I have installed JavaScript Development Tools Plugin for Eclipse, but i am not able to run or debug a JavaScript Project. </p>
  
  <p>I want to debug using the inbuilt Rhino Interpreter, not using a web browser. </p>
  
  <p>I have created a JavaScript project and when I try to create a run configuration, it says "Please select a valid project" and the run button is greyed out..</p>
