Extracting WSDL <type> elements with JWSDL

Question

Hello,

I am trying to read the Type elements from a WSDL. I need to extract the types information to extract the elements from the returned SOAP object. I have been experimenting with several classes over the last couple of days with no progress. Here is my code,

// Identify Simple Web Service Site with some good Types
String endpoint = "http://ws.cdyne.com/WeatherWS/Weather.asmx"; 
String wsdlURI = endpoint + "?WSDL";
// Now build the reader
WSDLFactory wsdlFactory = WSDLFactory.newInstance();
WSDLReader reader = wsdlFactory.newWSDLReader();
//Set features -- most are defaults but this is instructive
reader.setFeature("javax.wsdl.verbose",false);
reader.setFeature("javax.wsdl.importDocuments",true);
// Go read the WSDL from the URI
Definition definition = reader.readWSDL(null, wsdlURI);
// Extract the Types
Types types = definition.getTypes();
String strTypes = types.toString();
// Let's take a look
System.out.println(strTypes);

As you can see I am getting the WSDL from the URI. When I print out the strTypes I get,

SchemaExtensibilityElement ({http://www.w3.org/2001/XMLSchema}schema):
required=null
element=[s:schema: null]

The following is the WSDL showing only the defitions and types section,

I have tried DomBuilder and a couple of other methods but no luck so far. I have seen several posing asking the same question, however most of the methods don't seem to work. I am having no problem reading the messages, porttypes, bindings, and services. I just can't seem to get at the types corrrectly.

Update 07/29/10 -- I have started reading JWSDL (Java API's for WSDL ver. 1.2). The document describes a registration process for each exstensible element and attribute. This seems to be a lightweight API that allows you to access these type elements. The document is not very clear on how to access these elements -- at least to me! I will read it a couple of more times to see if brain osmosis will work. I think I am going in the right direction. Anyone have an example of using JWSDL and accessing the type elements?

Update 08/04/10 -- I still have not been able to exstract the types section with JWSDL. Has anybody ever used the Woden API? I just found it and I am going through the API. Seems to be written in 2008 so maybe a little more up to date. JWSDL seems to be written in 2006. Any help with extracting types from a WSDL using JWSDL or Woden would be very helpful.
