BPEL Invoke activity problem

Question

Hi,
I have done a BPEL process which invokes an external web service. The
Invoke activity throws the following exception:
"Unsupported Content-Type: text/html Supported ones are: [text/xml]"
Does anybody know why?
Thanks.

In the WSDL I'm calling, the binding is declared like this:
<binding name="PfServicioWSSoapBinding" type="impl:PfServicioWS">
<wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
<operation name="consultarUsuario">
<wsdlsoap:operation soapAction=""/>
<input name="consultarUsuarioRequest">
<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://DefaultNamespace" use="encoded"/>
</input>
<output name="consultarUsuarioResponse">
<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://client.pfirma" use="encoded"/>
</output>
</operation>
</binding>
I am newbie in WSDL and I don't understand this. I have always seen bindings declared liks this:
<binding name="NAME" type="TYPE">
<soap:binding transport="http://schemas.xmlsoap.org/soap/http" style="document"/>
<operation name="OP_NAME">
<soap:operation soapAction="SOAP_ACTION" style="document"/>
<input>
<soap:body use="literal"/>
</input>
<output>
<soap:body use="literal"/>
</output>
</operation>
</binding>
I think the error I am getting is related to this fact.
