My service implements Provider<SAXSource> in PAYLOAD service mode. The
following is my invoke method:
public SAXSource invoke(SAXSource request) throws WebServiceException {
try {
SAXSource response1 = (SAXSource)operationImpl.invoke(request);
StreamResult output = new StreamResult(new
OutputStreamWriter(System.out));
TransformerFactory xformFactory =
TransformerFactory.newInstance();
Transformer idTransform = xformFactory.newTransformer();
idTransform.transform(response1, output);
SAXSource response2 = (SAXSource)operationImpl.invoke(request);
XMLInputFactory factory = XMLInputFactory.newInstance();
XMLStreamReader reader =
factory.createXMLStreamReader(response2);
while (reader.hasNext()) {
int eventType = reader.next();
System.out.println("**** event type="+eventType);
if (reader.isStartElement()) {
System.out.println("****
name="+reader.getName());
}
}
SAXSource response3 = (SAXSource)operationImpl.invoke(request);
return response3;
} catch (WebServiceException e){
throw e;
} catch (Exception e) {
String errorMsg = "Retrieve operation failed -
"+helper.getDataServiceName();
throw createInternalErrorFault(e, errorMsg);
}
}
response1, response2 and response3 are the same SAXSource. The output of
response1 and response2 on my console are not empty. However, I got an empty
Outbound Message for response3. Based on the trace, I noticed that the SAX
parser was invoked after the response3 was returned.
Does anybody know what causes this problem?
