One "difference", however, is that by the time we get to that code in CXF,
we have all the Schemas loaded as DOM's and/or XmlSchema object models. As
part of the WSDL processing, we resolve all the catalogs and such at that
point. Thus, we don't need to deal with the catalogs and such during the
schema validation things. You might be able to do similar things.
Actually, you COULD just use CXF for all of that. Something like: (using
CXF 2.6.0, <=2.5.x would be a bit different)
Bus bus = BusFactory.getDefaultBus();
Service service = bus.getExtension(WSDLServiceFactory.class)
.create(wsdlURL);
Schema s =
EndpointReferenceUtils.getSchema(service.getServiceInfos().get(0));
The CXF Bus would grab the META-INF/jax-ws-catalog.xml (or you could call:
OASISCatalogManager.getCatalogManager(bus).loadCatalog(url);
to add the catalog), load and process the WSDL and schemas for you, and then
create the Schema object that you can use for validation.
