The following article states that the WSDL_OPERATION property is optional and might be presented only if the binding has information about WSDL metadata.

Dmitry thanks for the update. This was an quick and dirty solution for the problem in hand.

Besides the problem you mentioned the way mentioned here works only for server side handlers not for client handlers as there are different classes being used by JAX-WS RI on client side. Anyway good news is that JAX-WS RI 2.2 will again provide operation name, hence no more dirty tricks :-)

Your solution works only for rpc operations, where name of first element in payload equal to operation name. If operation has style=document your will get name of element, not name of operation.

However I found solution using your code, here it is:

private QName getOperationName(SOAPMessageContext context) {
try {
QName operationName = null;
if (context.get(MessageContext.WSDL_OPERATION) != null) {
operationName = (QName) context.get(MessageContext.WSDL_OPERATION);
} else {
Field field = context.getClass().getSuperclass().getDeclaredField("packet");
field.setAccessible(true);
Packet packet = (Packet) field.get(context);

SOAPSEIModel seiModel = ((com.sun.xml.ws.client.sei.SEIStub) context
.get(BindingProviderProperties.JAXWS_CLIENT_HANDLE_PROPERTY)).seiModel;

String operationLocalName = packet.getMessage().getMethod(seiModel).getOperationName();
String portNamespace = ((QName)context.get(MessageContext.WSDL_PORT)).getNamespaceURI();
operationName = new QName(portNamespace, operationLocalName);
}
return operationName;
} catch (Exception e) {
throw new RuntimeException("Error while trying to get wsdl operation name", e);
}
}

It returns wsdl operation's QName for both rpc and document style operations.

So thank you for publish your solution :)
