Hi,
Regarding the Complex Tpyes, I had loads of problems too and took me very long to understand something on how to parse them successfully!
Breifly, the best approch, IMHO, is the following:
Get the the java.wsdl.Types from the java.wsdl.Definition object (that I assume you have).
One you have the Type object, its easy to get a schema element (org.w3c.dom.Element):
ExtensibilityElement schemaExtElem = findExtensibilityElement(pWSDLDefinition.getTypes().getExtensibilityElements(), "schema");
if ((schemaExtElem != null) && (schemaExtElem instanceof UnknownExtensibilityElement)) {
schemaElement = ((UnknownExtensibilityElement) schemaExtElem).getElement();
I then transformed my schemaElement into a JDOM element (org.jdom.Element) using org.jdom.input.DOMBuilder:
DOMBuilder domBuilder = new DOMBuilder();
org.jdom.Element jdomSchemaElement = domBuilder.build(schemaElement);
Once you have the JDOM element, it's easy to transform it into a Castor Schema (org.exolab.castor.xml.schema.Schema) using the SchemaReader (org.exolab.castor.xml.schema.reader.SchemaReader).
With Castor, its relativly easy to get what you need:
ElementDecl elementDecl = gTypesSchema.getElementDecl(part.getElementName().getLocalPart());
XMLType xmlType = elementDecl.getType();
if (xmlType.isComplexType()) {
// It's a complex type
ComplexType complexType = (ComplexType) xmlType;
There are probably other ways to do it (eg: PSVI), but I never found somebody in the mood to help!! ;)
All the best!
