Title: RE: Interoperability Axis with .NET (C#)

Using the Axis1.0 samples for encoding using custom serralizer/deserializer, I wish to pass an array of complex data types to .Net(C# Web Reference). In addition, I am using Java2Wsdl.

The C# .Net side Web Refernce auto-generated code catches System.InvalidOperationException: There is an error in XML document (5, 5). ---> System.InvalidOperationException: Namespace prefix 'null' is not defined.

Below is the relevant Java code:

</service>

public class ElementService

{

public Data[] getDataObjects()

    {
        Data[] dataObjects = new Data[3];
        dataObjects[0]= new Data();
        dataObjects[1]= new Data();
       dataObjects[2]= new Data();
        return(dataObjects);
    }

public String helloWorld()

    {
        System.out.println("testing...");
        return("Hello World!!");
    }

}

public class Data
{
public String stringMember;
public Float floatMember;

    public Data() {
        stringMember = "default string";
        floatMember = new Float(0.00);
    }

    public Data(String stringMember, Float floatMember) {
        this();
        this.stringMember = stringMember;
        this.floatMember = floatMember;
    }
}

public class DataSer implements Serializer
{

    public static final String STRINGMEMBER = "stringMember";
    public static final String FLOATMEMBER = "floatMember";

    public void serialize(QName name, Attributes attributes,
                          Object value, SerializationContext context)
        throws IOException
    {
       if (value instanceof Data) {

Data data = "">

           context.startElement(name, attributes);
           context.serialize(new QName("", STRINGMEMBER), null, data.stringMember);
           context.serialize(new QName("", FLOATMEMBER), null, data.floatMember);
           context.endElement();
       }
       else
          throw new IOException("Can't serialize a " + value.getClass().getName() + " with a DataSerializer.");

}

public String getMechanismType() { return Constants.AXIS_SAX; }

    public boolean writeSchema(Types types) throws Exception {
        return false;
    }
}

public class DataDeser extends DeserializerImpl
{
public static final String STRINGMEMBER = "stringMember";
public static final String FLOATMEMBER = "floatMember";

private Hashtable typesByMemberName = new Hashtable();

    public DataDeser()
    {
        typesByMemberName.put(STRINGMEMBER, Constants.XSD_STRING);
        typesByMemberName.put(FLOATMEMBER, Constants.XSD_FLOAT);
        value = new Data();
    }

     public SOAPHandler onStartChild(String namespace,
                                    String localName,
                                    String prefix,
                                    Attributes attributes,
                                    DeserializationContext context)
        throws SAXException
    {

QName typeQName = (QName)typesByMemberName.get(localName);

if (typeQName == null)
throw new SAXException("Invalid element in Data struct - " + localName);

// These can come in either order.
Deserializer dSer = context.getDeserializerForType(typeQName);

try {

            dSer.registerValueTarget(new FieldTarget(value, localName));
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
            throw new SAXException(e);
        }

if (dSer == null)
throw new SAXException("No deserializer for a " + typeQName + "???");

return (SOAPHandler)dSer;
}
}
