title: In GAE how do you *stop* running your app?
body: <p>I'm on Eclipse (Helios) using GAE SDK 1.5.2, etc. (Just updated everything, today.)</p>
  
  <p>"In the old days..." (earlier SDKs), when I ran/debug my app locally, it would create an app on my machine (Mac, OS-X 10.6.latest) and, when I wanted to quit it, I would just CMD-Q that app.</p>
  
  <p>Now, when I launch the app, it appears to run as a sub-process of Eclipse (assumption on my part -- I can't find any separate app that's running), and I can't seem to figure out how to quit the app.</p>
  
  <p>The specific problem I'm having is, after I change something and select <strong>Run -> Debug as... -> Web Application</strong> the 2nd time, I get "address in use" socket-binding error.</p>
  
  <pre><code>[ERROR] Unable to bind socket on port 9997 -- is another session active?
  java.net.BindException: Address already in use
  </code></pre>
  
  <p>I suspect that, yes, another session IS active (the one I started just 2 minutes ago!), and my question is: how do I stop that session?</p>
  
  <p>Thanks!</p>
