Subject [jira] Commented: (AXIS-2682) wsdl2Java generates invalid empty string namespaces
Date Wed, 25 Jul 2007 18:45:31 GMT

    [ https://issues.apache.org/jira/browse/AXIS-2682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12515379
] 

Tom Jordahl commented on AXIS-2682:
-----------------------------------

The construct
  <data xmlns="">foo</data>
Is to make the <data> element unqualified.  Since the element above (<AcceptBase64>)
defined a default namespace, in order to remove the data element from that default namespace,
Axis emits the xmlns="".  This is perfectly legal.

See http://www.w3.org/TR/xml-names/#defaulting - Section 6.2 Namespace defaulting.

I don't think there is a bug here...

> 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).
