Enhance adb binding union to default to type xs:any
---------------------------------------------------
Key: AXIS2-2900
URL: https://issues.apache.org/jira/browse/AXIS2-2900
Project: Axis 2.0 (Axis2)
Issue Type: Improvement
Components: adb
Affects Versions: 1.2
Environment: All platforms.
Reporter: Denis Rachal
adb binding support of union types expects the XML attribute xs:type to be
specified in the XML document when unmarshalling. If the xs:type attribute is
missing the unmarshal fails. This enhancement requests that if the xs:type
attribute is missing, the XML element be treated as an xs:any and unmarshal the
elemen as a dom element.
Example taken from: "http://schemas.xmlsoap.org/ws/2004/09/enumeration";
Type is 'ExpirationType'. Element set in message response is 'Expires':
<xs:simpleType name="NonNegativeDurationType">
<xs:restriction base="xs:duration">
<xs:minInclusive value="P0Y0M0DT0H0M0S"/>
</xs:restriction>
</xs:simpleType>
<xs:simpleType name="ExpirationType">
<xs:union memberTypes="xs:dateTime
tns:NonNegativeDurationType"/>
</xs:simpleType>
...
<!-- Enumerate response -->
<xs:element name="EnumerateResponse">
<xs:complexType>
<xs:sequence>
<xs:element name="Expires"
type="tns:ExpirationType" minOccurs="0"/>
<xs:element name="EnumerationContext"
type="tns:EnumerationContextType"/>
<xs:any namespace="##other"
processContents="lax" minOccurs="0" maxOccurs="unbounded"/>
</xs:sequence>
<xs:anyAttribute namespace="##other"
processContents="lax"/>
</xs:complexType>
</xs:element>
XML document example:
If the above case, the adb binding currently expects the following and will
fail during unmarshal if the attribute 'xs:type' is not specified:
...
<env:Body>
<wsen:EnumerateResponse xmlns:ns11="http://test.foo";
xmlns:ns12="http://examples.hp.com/ws/wsman/user";>
<wsen:Expires
xs:type="xs:dateTime">2147483647-12-31T23:59:59.999-14:00</wsen:Expires>
<wsen:EnumerationContext>70d7063f-1639-4cda-a7db-b4fb2638b738</wsen:EnumerationContext>
</wsen:EnumerateResponse>
</env:Body
...
If the following is sent, the adb binding should treat the value as 'xs:any'
and not throw a fault for an "Unexpected element" during unmarshal:
...
<env:Body>
<wsen:EnumerateResponse xmlns:ns11="http://test.foo";
xmlns:ns12="http://examples.hp.com/ws/wsman/user";>
<wsen:Expires>2147483647-12-31T23:59:59.999-14:00</wsen:Expires>
<wsen:EnumerationContext>70d7063f-1639-4cda-a7db-b4fb2638b738</wsen:EnumerationContext>
</wsen:EnumerateResponse>
</env:Body
...
