title: How to use HTML Component File(.htc) with GWT for applying CSS3?
body: <p>Rounded Borders not working in IE .
  I've tried to use CSS3 for my GWT web app , and I'm struggling to inject *.htc into my code.
  <br />How to reference   *.htc file via GWT; <br /><br />
  1.I've tried using <code>ClienBundle</code> to get it as a resource file.<br />
  2.I've referenced its relative path from css file.<br /><br />
  Both of the ways couldn't help me.
  <br />
  Is there any way using CSS3 with GWT?<br />
  Is anybody using *.htc with GWT or GWT doesn't support CSS3 yet?<br /><br />

      DataResource htcResource();
  }
  
  public void onModuleLoad() {
      final MyResources myResources=(MyResources) GWT.create(MyResources.class);
      final FlowPanel  roundedDiv =new FlowPanel();
      roundedDiv.setStyleName("myClass");
      roundedDiv.add(new Label("lorem ipsum dolor sit amet lorem dolor" +
              "sit amet lorem ipsum dolor sit amet "));
      roundedDiv.setSize("200px","200px");
      myResources.htcResource().getUrl(); //For what is this necessary?
      RootPanel.get().add(roundedDiv);
  }
  </code></pre>
  
  <p>}<br />
  <strong>myResources.htcResource().getUrl(); //For what is this necessary?</strong></p>
  
  <p>Css3.css</p>
  
  <pre><code>@url myHTCFile htcResource;
  
  .myClass {
    behavoir: url(css3/myHTCFile);
    border-radius:10px;
