Looking for some guidance on Axis1 version 1.4 help building a WS Client
that can interact with a MTOM WebService.
I am building the client using the Service and Call objects
The input to the service is a String and a Base64 encoded element -
looks like this
<arg0>
<name>TEST</name>
<binaryData>base64 stuff here</binaryData>
</arg0>
I have successfully called the service with null binaryData but I get
the following error when I pass actual data.
The output is the String sent back in a SOAP Fault
<soap:Text xml:lang ="en">Unmarshalling Error : null </soap:Text>
In this example I have a class HelloWorldMtom (JavaBean) with a String
and a DataHandler attributes that I use as input.
HelloWorldMtom hwMtom = new HelloWorldMtom();
hwMtom.setName(name);
hwMtom.setBinaryData(dh);
Here is the client code:
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(ADDRESS);
call.setOperationName(new QName(HELLO_NAMESPACE, "sayHello"));
call.setSOAPVersion(SOAPConstants.SOAP12_CONSTANTS);
call.setProperty(Call.ATTACHMENT_ENCAPSULATION_FORMAT,
Call.ATTACHMENT_ENCAPSULATION_FORMAT_MTOM);
call.setProperty(Call.SEND_TYPE_ATTR, Boolean.FALSE);
call.setReturnType(org.apache.axis.Constants.XSD_STRING);
call.setOperationStyle(Style.WRAPPED);
call.setOperationUse(Use.LITERAL);
QName qnameHelloMtom = new QName(HELLO_NAMESPACE, "helloMtom");
call.registerTypeMapping(hwMtom.getClass(), qnameHelloMtom, new
HelloWorldMtomSerializerFactory(), new
BeanDeserializerFactory(hwMtom.getClass(), qnameHelloMtom));
call.addParameter("arg0", qnameHelloMtom, ParameterMode.IN);
String ret = (String) call.invoke( new Object[] { hwMtom } );
I built a custom Serializer as follows:
public class HelloWorldMtomSerializer implements Serializer {
public void serialize(QName name, Attributes attributes, Object
value, SerializationContext context) throws IOException {
if (value!=null){
HelloWorldMtom data = (HelloWorldMtom)value;
context.startElement(new QName("arg0"), null);
context.serialize(new QName("name"), null,
data.getName(), null, Boolean.TRUE, Boolean.FALSE);
if (data.getBinaryData()!=null){
Serializer jafs = new
JAFDataHandlerSerializer();
jafs.serialize(new QName("binaryData"), null,
data.getBinaryData(), context);
}
else {
context.serialize(new QName("binaryData"), null,
null, null, Boolean.TRUE, Boolean.FALSE);
}
context.endElement();
}
}
public String getMechanismType() { return Constants.AXIS_SAX; }
public Element writeSchema(Class javaType, Types types) throws
Exception {
return null;
}
}
Am I on the right track?
Thanks for any help with this.
Note:
A CXF and an Axis2 WS client have already been successfully built
against this WS (I am testing interop with different Java SOAP stacks)
