Hi Nataliya, The schema document embedded in your WSDL is missing a required import:
<s:import namespace="http://www.w3.org/2001/XMLSchema"; schemaLocation="http://www.w3.org/2001/XMLSchema.xsd"/> This isn't just a validation error. The XSModel you've built is missing components. If you want to resolve this issue you need to add the import to the document. If you don't want to edit the file on disk you could add it to the DOM in memory before passing the schema root Element node to the XMLGrammarPreparser. The entity resolver gives your application an opportunity to do custom resolution of schemaLocations (e.g. redirecting to a local copy of XMLSchema.xsd) on includes/imports/redefines. There's an FAQ [1] on the XML Catalog resolver with some examples on the Xerces-J website. Note that it won't be called in this case unless you have an import for the "http://www.w3.org/2001/XMLSchema"; namespace in your schema. Thanks.
