title: GWT Servlet - ClassNotFoundException
body: <p>I am learning GWT by following their <a href="https://developers.google.com/web-toolkit/tools/gwtdesigner/tutorials/stockwatcher" rel="nofollow">StockWatcher tutorial</a>. After trying a few things on my own, I got this exception on a servlet:</p>
  
  <pre><code>Feb 28, 2013 7:55:00 PM com.google.apphosting.utils.jetty.JettyLogger info
  INFO: jetty-6.1.x

  <p>This is the web.xml file where I am configuring the servlet:</p>
  
  <pre><code>&lt;servlet&gt;
      &lt;servlet-name&gt;greetServlet&lt;/servlet-name&gt;
      &lt;servlet-class&gt;com.google.gwt.sc2.server.GreetingServiceImpl&lt;/servlet-class&gt;
  &lt;/servlet&gt;
  
  &lt;servlet-mapping&gt;
      &lt;servlet-name&gt;greetServlet&lt;/servlet-name&gt;
      &lt;url-pattern&gt;/bikeapp/greet&lt;/url-pattern&gt;
  &lt;/servlet-mapping&gt;
  </code></pre>
  
  <p>I think I'm missing something really basic, but I don't know what. Can anyone help please?</p>
