Add WMS Layer with ArcGIS API for Flex 2.4

[aaaa3]

Hi, I'm starting with the arcGIS API from Flex and my question is how can i add a layer to my flex application from a wms service [http://ovc.catastro.meh.es/Cartografia/WMS/ServidorWMS.aspx]??

esri:Map id="map">
 <esri:extent>
      <esri:Extent xmin="-1497990" ymin="4294192" xmax="896629" ymax="5407115">
           <esri:SpatialReference wkid="102100"/>
      </esri:Extent>
 </esri:extent>

 <esri:VETiledLayer
  id="veTiledLayer"
  key="{bingKey}"
  mapStyle="road"
  culture="es-ES"/>

</esri:Map>

Thanks
