Xinjun,
can you run tcpmon to capture the soap request and use that xml with
your stand alone program to see if that works?

Hi,
I wrote a sample custom serializer/deserializer to serialize an object. When
I use a standalone program to test the serializer, it works fine. But when I
deploy the serializer as part of a web service and and invoke the web
service through a SOAP request, I got the following null pointer execption.
I googled but didn't find the reason of this. Why does the NPE occur only
when I deploy the binder as part of the web service? I used the same
SOAPEnvelope to test.

The toObject method definition is as follows:
public CreditCardPaymentRequest toObject(QName qname, XMLStreamReader
reader) throws XMLStreamException {
CreditCardPaymentRequest obj = new CreditCardPaymentRequest();
String rootElementName = qname.getLocalPart ();
String uri = qname.getNamespaceURI();
if(!rootNsUri.equals(uri)) {
throw new XMLStreamException("Invalid namespace " + uri + ". Expected
namespace uri is " + rootNsUri);
}
while(reader.hasNext()) {
int type = reader.next(); // Line number: 138
if(XMLStreamConstants.START_ELEMENT == type){
String element = reader.getLocalName();
if( rootLocalName.equals(element) ) {
continue;
} else if( element.equals("cardNumber") ){
obj.setCardNumber(reader.getElementText());
} else if( element.equals("expiryMonth") ) {
obj.setExpiryMonth(reader.getElementText());
} else if( element.equals("expiryYear") ) {
obj.setExpiryYear(reader.getElementText());
} else if( element.equals("brand") ) {
obj.setBrand(reader.getElementText());
} else if( element.equals("totalAmount") ) {
obj.setTotalAmount(reader.getElementText());
} else if( element.equals("currency") ) {
obj.setCurrency(reader.getElementText());
} else if( element.equals("systemId") ) {
obj.setSystemId(reader.getElementText());
} else if( element.equals("referenceNumber") ) {
obj.setReferenceNumber(reader.getElementText());
} else if( element.equals("op") ) {
obj.setOp(reader.getElementText());
} else {
throw new RuntimeException("Unexpected element " + element);
}
}
if(XMLStreamConstants.END_ELEMENT == type){
if(reader.getLocalName().equals(rootElementName)){
break;
}
}
}
return obj;
}
