Dear All,
I'm trying to obtain the (simple) type definitions of "elements" within
soap encoded arrays. Here's an example of one such array declaration:
<xsd:attribute ref="soapenc:arrayType"
wsdl:arrayType="typens:CustomerReview[]"/>
Here the attribute, "arrayType" is a string, but the SOAP engine
understands that the string really contains objects of type
"typens:CustomerReview" as a single dimensional array. (Ugly way of
encoding your data, I know, but people seem to use this construction!)
My problem is, that when inspecting such an attribute, I want to resolve
the "typens:CustomerReview" (simple) type definition and view its
properties. Before calling the resolveSimpleTypeDefinition() method, I
need to find the URL which the namespace prefix "typens" represents. I had
a look in both the XSD and DOM apis and couldn't find a method to do this.
Does anybody know how to map prefixes to the URLs they represent? I'm sure
it must be really simple.
Thanks a lot,
Mark

Mark,
Here's some code that given a complex type that is a soap encoding array type
will return the resolved item type (or null otherwise):
protected Object
getSOAPEncodingArrayItemType(XSDComplexTypeDefinition
xsdComplexTypeDefinition)
{
if
(xsdComplexTypeDefinition.getBaseTypeDefinition().getURI().e quals(SOAP_ENCODING_ARRAY))
{
for (Iterator attributeContents =
xsdComplexTypeDefinition.getAttributeContents().iterator();
attributeContents.hasNext(); )
{
XSDAttributeUse xsdAttributeUse =
(XSDAttributeUse)attributeContents.next();
XSDAttributeDeclaration xsdAttributeDeclaration =
xsdAttributeUse.getAttributeDeclaration();
if (xsdAttributeDeclaration.getURI().equals(SOAP_ENCODING_URI
+ "#" + "arrayType"))
{
Element attributeElement = xsdAttributeUse.getElement();
if (attributeElement != null &&
attributeElement.hasAttributeNS(WSDL_URI, "arrayType"))
{
String arrayType =
attributeElement.getAttributeNS(WSDL_URI, "arrayType");
int index = arrayType.indexOf("[");
if (index != -1)
{
String arrayTypeURI =
XSDConstants.lookupQName(attributeElement, arrayType.substring(0,
index));
XSDTypeDefinition itemTypeDefinition =
xsdAttributeUse.resolveTypeDefinitionURI(arrayTypeURI);
return itemTypeDefinition;
}
}
}
}
}
return null;
}
