SAXParseException cannot resolve SOAP-ENC:Array to a type definition component

Question

I am trying to validate a SOAP response message against the WSDL and I'm following the sample given in this question. However, I get the exception below.

org.xml.sax.SAXParseException: src-resolve: Cannot resolve the name 'SOAP-ENC:Array' to a(n) 'type definition' component.

I've seen a question about a similar error but I'm not sure if this is the same issue. I also don't understand why SOAP-ENC:Array is considered non-standard in that question when it appears in the SOAP spec.

Here is my validation code. The exception is raised on the Schema schema = schemaFactory.newSchema(schemas) line.

DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document wsdlDoc = db.newDocument();
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer transformer = transformerFactory.newTransformer();
Source wsdlSource = new StreamSource(new File("d:\\temp\\demo.wsdl"));
transformer.transform(wsdlSource, new DOMResult(wsdlDoc));

NodeList schemaNodes = wsdlDoc.getElementsByTagNameNS(XMLConstants.W3C_XML_SCHEMA_NS_URI, "schema");
int nrSchemas = schemaNodes.getLength();

Source[] schemas = new Source[nrSchemas];
for (int i = 0; i < nrSchemas; ++i)
{
  schemas[i] = new DOMSource(schemaNodes.item(i));
}

SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = schemaFactory.newSchema(schemas);
Validator validator = schema.newValidator();
Source soapMessage = new StreamSource(new File("d:\\temp\\soapmessage.xml"));
Result result = new StreamResult(System.out);
validator.validate(soapMessage, result);

I've trimmed the WSDL and only left the relevant parts, or at least what I think is relevant. If more is needed, I'll update the question.

The immediate problem is that the schema validator being called is not loading any schema document for namespace http://schemas.xmlsoap.org/soap/encoding/ -- either because it's a generic validator and doesn't have any inbuilt knowledge of SOAP namespaces, or because it did not manage to retrieve the schema document from the server at schemas.xmlsoap.org.

If you have a local copy of the schemas for the http://schemas.xmlsoap.org/soap/encoding/ and http://schemas.xmlsoap.org/wsdl/ namespaces, you might try adding schema location information to the two xsd:import elements in your schema. If you don't have a local copy, then I hope you have better luck getting responses out of schemas.xmlsoap.org than I did just now.
