wps external wfs request

[Samanta]

Buonasera,

sto provando a chiamare in una richiesta wps un wfs esterno, nel seguente modo:

<?xml version="1.0" encoding="UTF-8"?><wps:Execute version="1.0.0" service="WPS" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.opengis.net/wps/1.0.0" xmlns:wfs="http://www.opengis.net/wfs" xmlns:wps="http://www.opengis.net/wps/1.0.0" xmlns:ows="http://www.opengis.net/ows/1.1" xmlns:gml="http://www.opengis.net/gml" xmlns:ogc="http://www.opengis.net/ogc" xmlns:wcs="http://www.opengis.net/wcs/1.1.1" xmlns:xlink="http://www.w3.org/1999/xlink" xsi:schemaLocation="http://www.opengis.net/wps/1.0.0 http://schemas.opengis.net/wps/1.0.0/wpsAll.xsd">

    <wps:RawDataOutput>
      <ows:Identifier>bounds</ows:Identifier>
    </wps:RawDataOutput>
  </wps:ResponseForm>
</wps:Execute>

ma quando lo provo ad eseguire ho il seguente errore:

Caused by: java.lang.ClassCastException: java.util.HashMap cannot be cast to net.opengis.wfs.FeatureCollectionType

Qualcuno sa aiutarmi o ha già avuto questo problema?

Grazie mille!!
