title: eclipse rcp change icon for xml configuration file
body: <p>I built an Eclipse RCP application that uses the <code>configuration.xml</code> in the root of the project for some project configurations. I would like to customize the icon and keep default xml editor. I found one blog <a href="http://blog.eclipse-tips.com/2008/04/content-type-specific-file-icons.html" rel="nofollow">post</a>, that does exactly what I'm looking for a <code>property</code> file. I extracted it:</p>
  
  <pre><code>&lt;extension point="org.eclipse.core.contenttype.contentTypes"&gt;
    &lt;content-type base-type="org.eclipse.core.runtime.properties"
      file-extensions="config"
      id="in.cypal.eclipse.myConfig"
      name="My Config File"
      priority="normal"&gt;
    &lt;/content-type&gt;
  &lt;/extension&gt;
  
  &lt;extension point="org.eclipse.ui.editors"&gt;
    &lt;editor class="org.eclipse.jdt.internal.ui.propertiesfileeditor.PropertiesFileEditor"
      default="false"
      extensions="config"
      icon="icons/sample.gif"
      id="in.cypal.eclipse.editors.myConfigEditor"
      name="My Config Editor"&gt;
        &lt;contentTypeBinding contentTypeId="in.cypal.eclipse.myConfig"&gt;
        &lt;/contentTypeBinding&gt;
    &lt;/editor&gt;
  &lt;/extension&gt;
  </code></pre>
  
  <p>I guess that I basically need to adjust the attribute <code>class</code> of the <code>editor</code> element to the implementation of the xml editor in Eclipse. I installed the <code>org.eclipse.wst.xml_ui.feature.feature.group</code>. I'm not able to find the right implementation. Please help :) Thank you!</p>
