Serialization and "Not So" Simple Types

[He...@bcbsil.com]

I am having an issue with attributes defined within a complex type and the
serialization of these attributes. An example below how I define the
attributes within our complex type.

      <xs:complexType name="memb-ssni-parms-type">
      <xs:attribute name="req-search-date">
        <xs:simpleType>
          <xs:restriction base="xs:string">
            <xs:whiteSpace value="collapse"/>
            <xs:minLength value="10" />
            <xs:maxLength value="10" />
          </xs:restriction>
        </xs:simpleType>
      </xs:attribute>
      .....
      .....
      <xs:complexType>

Now the attribute is also correctly defined in the MembSsniParamsType class

        attrField = new org.apache.axis.description.AttributeDesc();
        attrField.setFieldName("reqSearchDate");
        attrField.setXmlName(new javax.xml.namespace.QName("",
"req-search-date"));
        attrField.setXmlType(new javax.xml.namespace.QName(
"http://mycompany.com/eai/memb-ssni.xsd",
">memb-ssni-parms-type>req-search-date"));
        typeDesc.addFieldDesc(attrField);

I deploy this on our Axis Server and  in the server-config.wsdd I have the
below for the attribute
            <typeMapping deserializer=
"org.apache.axis.encoding.ser.SimpleDeserializerFactory" encodingStyle=""
qname="ns3:&gt;memb-ssni-parms-type&gt;req-search-date" serializer=
"org.apache.axis.encoding.ser.SimpleSerializerFactory" type=
"java:java.lang.String" xmlns:ns3="http://mycompany.com/eai/memb-ssni.xsd"
/>

I get the following exception when I try to view the WSDL from the Axis
services page..

After digging through the Axis code, I find that it fails on this method in
the  org.apache.axis.wsdl.fromJava.Types class

    boolean isSimpleType(Class type) {

        QName qname = tm.getTypeQName(type);

        if (qname == null) {
            return false;    // No mapping
        }

        String nsURI = qname.getNamespaceURI();

        return (Constants.isSchemaXSD(nsURI) ||
Constants.isSOAP_ENC(nsURI));
    }


In the above code type is String.class and it looks up the associated QName
in the registry and gets me back
{http://mycompany.com/eai/memb-ssni.xsd}>memb-ssni-parms-type>req-search-date

And this fails on the last line of the method Constants.isSchemaXSD(nsURI)
as this is not in the default Schema namespace.


First off, is this a bug? Because, it is still a simple type but it has the
namespace of the document rather than the default Schema namespace and I
add extensions on the simple type

What can I do to fix this?
Do I define a custom serializer that extends SimpleSerializer?
Can I change something on the schema?

Any help appreciated.

Thanks
