  <p>this is how my web.xml looks like</p>
  
  <pre><code>&lt;servlet&gt;
  &lt;servlet-name&gt;chatComet&lt;/servlet-name&gt;
  &lt;servlet-class&gt;net.zschech.gwt.comet.server.CometServlet&lt;/servlet-class&gt;
  &lt;/servlet&gt;
  
  &lt;servlet&gt;
  &lt;servlet-name&gt;chatServiceImpl&lt;/servlet-name&gt;
  &lt;servlet-class&gt;birgit.chat.server.ChatServiceImpl&lt;/servlet-class&gt;
  &lt;/servlet&gt;
  
  &lt;servlet-mapping&gt;
  &lt;servlet-name&gt;chatServiceImpl&lt;/servlet-name&gt;
  &lt;url-pattern&gt;/birgit.chat.Chat/chat&lt;/url-pattern&gt;
  &lt;/servlet-mapping&gt;
  </code></pre>
  
  <p>This is my Chat.gwt.xml</p>
  
  <pre><code>   &lt;!DOCTYPE module SYSTEM "http://google-web-toolkit.googlecode.com/svn/trunk/distro-         source/core/src/gwt-module.dtd"&gt;
       &lt;module &gt;
  &lt;inherits name="com.google.gwt.user.User" /&gt;
  &lt;inherits name="com.google.gwt.user.theme.standard.Standard" /&gt;
  &lt;inherits name="net.zschech.gwt.comet.Comet" /&gt;
  &lt;servlet class="birgit.chat.server.ChatServiceImpl" path="/chat"/&gt;
  &lt;entry-point class="birgit.chat.client.ChatEntryPoint" /&gt;
      &lt;/module&gt;
  </code></pre>
  
  <p>Those are packages i use </p>
  
  <pre><code>package birgit.chat.client;
  package birgit.chat.server;
  </code></pre>
  
  <p>I think there is something wrong with path but i am out of ideas.</p>

  Thank you.</p>
