Hi Claus,
Tuscany doesn't automatically load metadata (schemas) on the fly. You need
to register the types before you load the instances. You need to execute
something like this before calling XMLHelper.load():
URL url = SdoDroolsTest.class.getResource("/person.xsd");
getScope().getXSDHelper().define(url.openStream(), url.toString());
Automatically registering types, based on schemaLocation attributes in the
XML, is something we've talked about adding as a load option, but nobody
has found the time to look into implementing it.
Frank.
