[Axis2] Response already committed exception with binary data

[Sagara Gunathunga]

Hi Guys,
I try to send a binary file from server to client when invoking a  web
service  and but getting  "Response already committed" exception on server
side.
here I have given a simple example  for illustrate this problem ( I use
Axis2 1.4.1) . I'm  really appreciate if some one can provide a direction
for this  ?


Server side
----------------------------
ublic class BinaryService {

    public static final String fileName1 =
"doBinaryWithDataHandler-outputfile.jpg";

    public DataHandler doBinaryWithDataHandler() {

             FileDataSource dataSource = new FileDataSource(fileName1);
             System.out.println(" dataSource create ..........."+
dataSource.getName());
             DataHandler fileDataHandler = new DataHandler(dataSource);
             System.out.println(" fileDataHandler create ........."+
fileDataHandler.getName());
             return fileDataHandler;

    }

}


<service name="Binary-service2">
    <parameter name="ServiceClass">service.BinaryService
    </parameter>
    <operation name="doBinaryWithDataHandler">
        <messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out";
            class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
    </operation>
    <parameter name="enableMTOM">true</parameter>
</service>



client side
------------------------------------

RPCServiceClient client;
        try {
            client = new RPCServiceClient();
            Options opts = new Options();
            opts.setAction("ns:doBinaryWithByteArray");
            EndpointReference to = new EndpointReference();
            to.setAddress("
http://localhost:8080/axis2/services/MTOM-service2";);
            opts.setTo(to);
            client.setOptions(opts);
            //DataHandler dh = new DataHandler(new
FileDataSource("/home/sagara/Desktop/img.jpg"));
            OMElement node=client.invokeBlocking(new QName("http://service";,
"doBinaryWithDataHandler"),
            new Object[] { null});
            _    _
        }


error
---------------------------------------------

 fileDataHandler create .........doBinaryWithDataHandler-outputfile.jpg
