I am not sure if this falls exclusively within the remit of Oxygen or not, so apologies if it is not an Oxygen Problem I Have a WSDL and XSD in oxygen that test and verify without error. If However I copy the files to my server and run them, then I get an error. "java.io.IOException: Type {http://www.w3.org/2000/10/XMLSchema}uriReference <http://www.w3.org/2000/10/XMLSchema%7duriReference> is referenced but not defined." I don't understand why this is, but as it is in the standard files, I think I'm limited to what I can do. Is this a fault of the way I am using oxygen, or my apache system, or does oxygen just not check / test everything fully?
