title: Google App Engine with Eclipse?
body: <p>I'm trying to use Google App Engine with Eclipse but it's not working.</p>
  
  <p>I downloaded PyDev, and made a Hello World Python app, so that's working fine.</p>
  
  <p>Then I created a new project, with the "Google App Engine" template. I was following these <a href="http://code.google.com/appengine/articles/eclipse.html" rel="nofollow noreferrer">instructions</a>. I used the "Hello Webapp World" as a template, and didn't change any of the Python code. I added the GAE directory to my external libraries.</p>
  
  <p>I then made a run configuration for my project, with the "Main Module" as the "HelloWorld.py" file I had created. I had one "Program Argument":</p>
  
  <pre><code>"${project_loc}/src"
  </code></pre>
  
  <p>Running this returns the following:</p>
  
  <pre><code>Status: 404 Not Found

  </code></pre>
  
  <p>However, if I launch this same app using the Google App Engine Launcher, it works fine. So what am I doing wrong in Eclipse?</p>
