DataHandler and WSDL2Java

[Riess, Joseph C. (LNG)]

Has anyone had any luck getting WSDL2Java to automatically generate a type
mapping which uses the JAFDataHandlerSerializer/Deserializer factory objects
for javax.activation.DataHandler objects?  Here are the schemas that I'm
using:

DataHandler.xsd:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"; 
        targetNamespace="http://activation.javax"; 
        xmlns:tns="http://types.retrieval.services.jgateway.lexisnexis.com"; 
        elementFormDefault="qualified" 
        attributeFormDefault="unqualified" 
        version="1.0">

   <!-- Define Types -->
   <complexType name="DataHandler">
      <sequence/>
   </complexType>

</schema>

DocRetrieve.xsd:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://www.w3.org/2001/XMLSchema"; 
 
targetNamespace="http://types.retrieval.services.jgateway.lexisnexis.com"; 
        xmlns:tns="http://types.retrieval.services.jgateway.lexisnexis.com"; 
        xmlns:activation="http://activation.javax"; 
        xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"; 
        xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"; 
        elementFormDefault="qualified" 
        attributeFormDefault="unqualified" 
        version="1.0">

   <import namespace="http://activation.javax";  
 
schemaLocation="http://localhost:8080/Jgateway/schemas/retrieval/DataHandler
.xsd"/>
   ...

   <complexType name="DocumentList">
      <sequence>
         <element name="document" type="activation:DataHandler"
maxOccurs="25"/>
      </sequence>
   </complexType>

   ...

</schema>

By default, the type mappings which are generated from this schema use the
generic BeanSerializer/Deserializer factories, which in turn does not
generate a MIME response.  

e.g.   <typeMapping
        xmlns:ns="http://activation.javax";
        qname="ns:DataHandler"
        type="java:javax.activation.DataHandler"
        serializer="org.apache.axis.encoding.ser.BeanSerializerFactory"
        deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory"
        encodingStyle=""
      />

If I change these mappings to use the JAFDataHandlerSerializer/Deserializer
factories, things work as they should.  Why doesn't the emitter use this
mapping by default for DataHandler types?
