Hi all,
I'm doing some tests and I get the following exception:
Exception in thread "pool-1-thread-1" java.lang.NullPointerException

while this is the chunk of code you can use to re-create the problem
(the problem occurs on mepClient.execute() while the fault is created
according to here [1]):
void failure3(Request request) throws AxisFault {
final MessageContext inMessageContext = request.context;
SOAPFactory soapFactory;
if (inMessageContext.isSOAP11()) {
soapFactory = OMAbstractFactory.getSOAP11Factory();
} else {
soapFactory = OMAbstractFactory.getSOAP12Factory();
}
SOAPFaultCode soapFaultCode = soapFactory.createSOAPFaultCode();
SOAPFaultValue soapFaultValue =
soapFactory.createSOAPFaultValue(soapFaultCode);
soapFaultValue.setText(new QName("http://test.org";, "TestFault",
"test"));
SOAPFaultReason soapFaultReason =
soapFactory.createSOAPFaultReason();
SOAPFaultText soapFaultText =
soapFactory.createSOAPFaultText(soapFaultReason);
soapFaultText.setText("This is some FaultReason");
SOAPFaultDetail soapFaultDetail =
soapFactory.createSOAPFaultDetail();
QName qName = new QName("http://someuri.org";, "FaultException");
OMElement detail = soapFactory.createOMElement(qName,
soapFaultDetail);
qName = new QName("http://someuri.org";, "ExceptionMessage");
Throwable e = new Exception("This is a test Exception");
OMElement exception = soapFactory.createOMElement(qName, null);
exception.setText(e.getMessage());
detail.addChild(exception);
MessageContext outMessageContext = new MessageContext();
outMessageContext.setProperty(SOAP12Constants.SOAP_FAULT_CODE_LOCAL_NAME,
soapFaultCode);
outMessageContext.setProperty(SOAP12Constants.SOAP_FAULT_REASON_LOCAL_NAME,
soapFaultReason);
outMessageContext.setProperty(SOAP12Constants.SOAP_FAULT_DETAIL_LOCAL_NAME,
soapFaultDetail);
Options options = new Options();
options.setTransportInProtocol(Constants.TRANSPORT_HTTP);
options.setSoapVersionURI(SOAP12Constants.SOAP_ENVELOPE_NAMESPACE_URI);
options.setTo(inMessageContext.getReplyTo());
// these statements are needed -- otherwise the server fails
options.setAction("urn:echoResponse");
options.setRelationships(new RelatesTo[] { new
RelatesTo(inMessageContext
.getOptions().getMessageId(),
AddressingConstants.Submission.WSA_DEFAULT_RELATIONSHIP_TYPE) });
sender.setOptions(options);
// outMessageContext.setOptions(options);
OperationClient mepClient =
sender.createClient(ServiceClient.ANON_OUT_ONLY_OP);
mepClient.addMessageContext(outMessageContext);
mepClient.execute(true);
mepClient.complete(outMessageContext);
sender.cleanupTransport();
}
Please not that the operation is declared as in-oly and it's
asyncronous. If the above method is invoked by the received thread,
i.e.:
public class MyService {
public void test(OMElement element) {
failure3(new Request(element,
MessageContext.getCurrentMessageContext());
}
}
then the client gets the following error:
<?xml version='1.0' encoding='utf-8'?>

soapenv:Server</faultcode>

My idea, however, is to handle the request using a separate thread --
the receiver and the worker thread are connected via a queue. In this
scenario the same error occurs but the client is never notified -- it
keeps waiting until a timeout error occurs.
Any idea?
