title: Eclipse "This selection cannot be launched and there are no recent launches" processing error
body: <p>I've been trying to do processing in eclipse by downloading processing and running it with eclipse. Every time I try to run anything it says "This selection cannot be launched and there are no recent launches" <strong>I've looked around for the same problem but none of them are for processing and mostly just for default java or android</strong> I've tried to make a run configuration but to no avail.
  code</p>
  
  <pre><code>import processing.core.PApplet;
  import processing.core.PImage;
  
  
  public class processing extends PApplet
  {
  PImage background;
  PImage paddleImage;
  
  public void setup()
  {
      size(800, 600);
      background = loadImage("background.png");
      paddleImage = loadImage("paddle.png");
  }
  public void draw()
  {
      background(background);
  }
  public class Paddle
  {
      PImage sprite;
      float xPos;
      float yPos;
  
      public Paddle(PImage paddleSprite, float xStart, float yStart)
      {
          sprite = paddleSprite;
          xPos = xStart;
          yPos = yStart;
      }
  }
  }
  </code></pre>
