Spring-ws processing messages with no Soap Header tag

[ronnelson929]

I have been re-writing an existing webservice with Spring-ws to take advantage of maven for dependency management and profiling the build process. I also updated the project from outdated xfire jars to using spring-ws.

The current production webservice passes a Soap request like this

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
	<soap:Body>
		<getTaxID xmlns="http://acdt1403:8080/CustKeyService">
			<id>some string</id>
		</getTaxID>
	</soap:Body>
</soap:Envelope>

And the response is returned like this

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
	xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
	<soap:Body>
		<getTaxIDResponse xmlns="http://acdt1403:8080/CustKeyService">
			<out>some value</out>
		</getTaxIDResponse>
	</soap:Body>
</soap:Envelope>

Notice there is no <soap:Header /> element. From what I've seen this is not required. When I use the contract first approach to recreate the existing wsdl, it seems to create the same wsdl used for consumption today. However, when Spring-ws processes this it throws a fault because the soap-header is null.

I can get into the appropriate methods, but it looks like I've only triggered a race condition because about half way through the method it throws a null pointer exception when trying to process the soap message. The following error is returned to the web service client

Error getting tax id: exception = System.Web.Services.Protocols.SoapHeaderException: java.lang.NullPointerException
at System.Web.Services.Protocols.SoapHttpClientProtoc ol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)

Has anyone dealt with this or does anyone have a suggestion around it?

Would it help to see the xsd document defined for the service?

It will be very helpful if we denote some time in maintaining our code styles so that it can be modified from time to time.
