Re: No Deserializer found

[Scott Nichol <sn...@scottnichol.com>]

The service is returning the value in an XML element (named 'return') that
has no xsi:type attribute.  Therefore, your client must provide a type
mapping for this element, such as by adding code like:

    SOAPMappingRegistry smr = new SOAPMappingRegistry();
    smr.mapTypes(Constants.NS_URI_SOAP_ENC,
                 new QName("", "return"),
                 null, null, new FloatDeserializer());
    call.setSOAPMappingRegistry(smr);
