[jira] Created: (AXIS-2682) wsdl2Java generates invalid empty
striung namespaces
wsdl2Java generates invalid empty striung namespaces
----------------------------------------------------
Key: AXIS-2682
URL: https://issues.apache.org/jira/browse/AXIS-2682
Project: Axis
Issue Type: Bug
Components: WSDL processing
Affects Versions: 1.4
Environment: Eclipse 3.2 on Mac OS 10.4.10 (Intel)
Reporter: Christoph Ludwig
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).

[jira] Commented: (AXIS-2682) wsdl2Java generates invalid empty
string namespaces
Posted by "Christoph Ludwig (JIRA)" <ax...@ws.apache.org>.

Christoph Ludwig commented on AXIS-2682:
----------------------------------------
I realized after submitting the issue report that the attribute xmlns="" is used to bring the elements back into the global namespace in case an outer element changed the default namespace and can be certainly valid. Thus, the first part of my report was in fact misleading, sorry.
The real problem is, though, that in my example both the data and the length element do not belong to the global namespace but to "http://www.textgrid.de/tests/bytearray/". (By accident, I submitted the report before I was finished, therefore this is mentioned in the first comment only.)
So the subject of this issue should rather read "WSDL2Java spuriously puts complex type members in the global namespace". And that *is* a bug, I think...

[jira] Commented: (AXIS-2682) wsdl2Java generates invalid empty
string namespaces
Posted by "Tom Jordahl (JIRA)" <ax...@ws.apache.org>.

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...

[jira] Commented: (AXIS-2682) wsdl2Java generates invalid empty
striung namespaces
Posted by "Christoph Ludwig (JIRA)" <ax...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/AXIS-2682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12514500 ]
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
