Christoph Ludwig commented on AXIS-2682:
----------------------------------------

Sorry, I accidentally submitted the issue before I was finished...

Even if the empty string vas a valid namespace name, the generated SOAP does 
not correspond to the WSDL that puts both data and length in 
"http://www.textgrid.de/tests/bytearray/";.

This issue seems related to issue AXIS-443. There James Snell claims this 
happens only if the WSDL does not define a targetNamespace for the xsd:schema 
tag. However, my WSDL file *does* define the targetNamespace attribute for both 
the schema and the WSDL, so this is not the cause in my case.

I can fix this manually in the generated stub and skeleton, of course, but I 
think WSDL2Java should generate the correct QNames in the first place.

Regards

Christoph

>          Components: WSDL processing

> I generated with WSDL2Java a service skeleton and client stubs for the 
> attached WSDL which I used for interoperability tests. When I investigated 
> errors, I found the following in the generated SOAP request:
>   <?xml version="1.0" encoding="UTF-8"?>
>      <soapenv:Envelope 
> xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; 
> xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
>         <soapenv:Body>
>            <AcceptBase64 xmlns="http://www.textgrid.de/tests/bytearray/";>
>               <data xmlns="">SGVsbG8gV29ybGQh</data>
>               <length xmlns="">12</length>
>            </AcceptBase64>
>         </soapenv:Body>
>      </soapenv:Envelope>
> Note the empty namespaces in the data and length elements. The W3C 
> recommendation "Namespaces in XML 1.0" states explicitly: "The empty string, 
> though it is a legal URI reference, cannot be used as a namespace name" 
> (http://www.w3.org/TR/xml-names/#iri-use).
