CLONE -Subclass elements in web service response returned with type="fully qualified class name" instead of xsi:type="ns:SchemaType"
------------------------------------------------------------------------------------------------------------------------------------

                 Key: AXIS2-4766
                 URL: https://issues.apache.org/jira/browse/AXIS2-4766
             Project: Axis2
          Issue Type: Bug
          Components: adb
    Affects Versions: 1.3
            Reporter: Murugadas Karunanithi
            Priority: Critical


Axis2 service returns type="com.bmc.bcan.dto.SubjectLinesDTO" instead of xsi:type="ns1:SubjectLinesDTO" in soap response.

This causes issues when the response has elements of sub-types.

Snippet from WSDL definition:

- <xs:complexType name="RuleDTO">
- <xs:sequence>
  <xs:element minOccurs="0" name="annotation" nillable="true" type="xs:string" /> 
  <xs:element maxOccurs="unbounded" minOccurs="0" name="applicableTrails" nillable="true" type="xs:int" /> 
  <xs:element minOccurs="0" name="deviceTypeId" nillable="true" type="xs:int" /> 
...
  <xs:element minOccurs="0" name="subject" nillable="true" type="ax21:SubjectDTO" /> 
</xs:sequence>
 </xs:complexType>

Definition of SubjectDTO (which has following sub types).

<xs:complexType name="SubjectDTO">
- <xs:sequence>
  <xs:element minOccurs="0" name="caseSensitive" type="xs:boolean" /> 
  <xs:element minOccurs="0" name="frequency" nillable="true" type="xs:int" /> 
  <xs:element minOccurs="0" name="ignoreWhitespace" type="xs:boolean" /> 
  <xs:element minOccurs="0" name="key" nillable="true" type="ax21:KeyDTO" /> 
  <xs:element minOccurs="0" name="COMPONENT_CLASSNAME" nillable="true" type="xs:string" /> 
  </xs:sequence>
  </xs:complexType>


- <xs:complexType name="SubjectCollectionDTO">
- <xs:complexContent>
- <xs:extension base="ax21:SubjectDTO">
- <xs:sequence>
  <xs:element maxOccurs="unbounded" minOccurs="0" name="collection" nillable="true" type="xs:string" /> 
  <xs:element minOccurs="0" name="contiguous" type="xs:boolean" /> 
  <xs:element minOccurs="0" name="ordered" type="xs:boolean" /> 
  </xs:sequence>
  </xs:extension>
  </xs:complexContent>
  </xs:complexType>

- <xs:complexType name="SubjectLinesDTO">

            </return>

The base type in RuleDTO has been defined as SubjectDTO. Since the type attribute is not xsi:type
in the client SubjectDTO.Factory.parse() is called which can't find the elements of sub-type

Is this a know issue. Any fix or axis services.xml parameter on the server side will be helpful.
