Hi,
You may want to look at the samples provided on the Web Services Developer's Guide.
see "Examples of Web Service Clients that use DII".
As the WSDL does have a schema import, the issue may be in accessing the document "EdgeClientCallback.xsd" - you may want to verify that the expected schema can be found on the URL you are using for your WSDL, when you manually place the schema name on the right context root.
Hope it helps,
Eric
