using SchemaType.getFullJavaName with dynamically compiled schema
I would like to do the following:
(1) Compile a schema on the fly using XmlBeans.compileXsd
(2) Inspect the resulting SchemaType instances to get information about
their underlying Java methods so that I can use these methods to
manipulate the instances.
But, it seems that the compileXsd method (below) does not create the
"Java Types Generated from User-Derived Schema" (as defined in
docs/guide/conJavaTypesGeneratedFromUserDerived.html), but only the
SchemaTypeSystem representations.
public static SchemaTypeSystem compileXsd(XmlObject[] schemas,
SchemaTypeLoader typepath,
XmlOptions options)
throws XmlException
It seems that if I want to generate the Java Types, then I would need to
use XmlBeans.compileXmlBeans. But, in order to use that method, I need
to get an instance of BindingConfig and Filer, which seem to be empty
implementations at this point.
How can I create te Java Types on the fly so that methods such as
SchemaType.getFullJavaName will work? Right now, these methods always
return null.
My code and sample output are below.
Code Snippet
============
SchemaTypeSystem schemaTypeSystem = XmlBeans.compileXsd
(new XmlObject[] {schema}, XmlBeans.getBuiltinTypeSystem(), null);
SchemaTypeLoader schemaTypeLoader = XmlBeans.typeLoaderUnion(
new SchemaTypeLoader[] { schemaTypeSystem,
XmlBeans.getBuiltinTypeSystem() });
QName poElementQName = new QName("http://javector.com/samples",
"PurchaseOrder");
SchemaType poElementType =
schemaTypeLoader.findElement(poElementQName).getType();
String poElementJavaName = poElementType.getFullJavaName();
System.out.println("PurchaseOrder element (root) has signature: " +
poElementType.toString());
System.out.println("PurchaseOrder element (root) has java class: " +
poElementJavaName);
Output
======
PurchaseOrder element (root) has signature:
E=PurchaseOrder|D=PurchaseOrder@http://javector.com/samples
PurchaseOrder element (root) has java class: null
