Axis2: Empty Soap response

[Ramakrishna Soma <ra...@gmail.com>]

Hi

I have a web-service that returns a (complex) bean- which I created
from a schema using JaxMe.. The web-service always returns an empty
response. I have a system.out just before the return in the
web-service method and the bean prints perfectly well

<?xml version='1.0' encoding='utf-8'?><soapenv:Envelope
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Header
/>
<soapenv:Body>
<ns:getRecoveryCurveResponse xmlns:ns="http://cisoft.usc.edu/iam"><return />
</ns:getRecoveryCurveResponse>
</soapenv:Body>
</soapenv:Envelope>

I have attached the wsdl file, soap request and the source for the
Java-bean as well.

As an attempt to isolate/understand the problem, I tried to
cut-n-paste the following (and the relevant pieces of) code from the
RPCUtil and BeanUtil classes:

            XMLStreamReader xr = getPullParser(r,new QName("return"));
            StAXOMBuilder stAXOMBuilder =
                    OMXMLBuilderFactory.createStAXOMBuilder(
                            OMAbstractFactory.getOMFactory(), new
StreamWrapper(xr));
            OMElement documentElement =  stAXOMBuilder.getDocumentElement();
            System.out.println(documentElement);

I get the following exception:

 Hope I am not doing something stupid..
