CXF client expects namespace, server doesn't send one.

I have a problem in which CXF generated client code expects a namespace as part of the web-service response. However, the web-service does not include a namespace as part of the response. This causes an unexpected element error. How can I configure the client to ignore the missing namespace? Plain old java, no Spring.

Here's a snippet of the exception the client throws... Exception in thread "main" javax.xml.ws.soap.SOAPFaultException: Unexpected wrapper element getResponse found.   Expected {http://www.service-now.com/fooservice}getResponse.

And here's the preamble for the wsdl..

Doing this WSDL first. I pulled the WSDL directly from the server. I had actually found the thread you linked to, but it isn't much help. A lot of people talk about modifying the @WebParam annotation, but the CXF wsdl2java doesn't generate any @WebParams.


Here's a sample of the generated client code...

Are you doing Java first or WSDL first?
An error like this usually indicates that the server or the client is generated against a faulty/changed interface.

What changes would need to be made here to get the client to fixed the "found response, expected {com.service_now.fooservice}response" to of error.

    @RequestWrapper(localName = "get", targetNamespace = "http://www.service-now.com/fooservice", className = "com.service_now.fooservice.Get")
    @WebMethod(action = "http://www.service-now.com/fooservice/get")
    @ResponseWrapper(localName = "getResponse", targetNamespace = "http://www.service-now.com/fooservice", className = "com.service_now.fooservice.GetResponse")
    public void get(
        @WebParam(mode = WebParam.Mode.INOUT, name = "sys_id", targetNamespace = "")
        javax.xml.ws.Holder<java.lang.String> sysId,
        @WebParam(name = "__use_view", targetNamespace = "")
        java.lang.String useView,

Now there's a clue. There is a WebParam annotation, but it defines empty values. From the interface file...

@WebService(targetNamespace = "http://www.service-now.com/fooservice", name = "ServiceNowSoap")
@XmlSeeAlso({ObjectFactory.class})
public interface ServiceNowSoap {

    @WebResult(name = "getRecordsResult", targetNamespace = "")

Ouch, then it kinda sorta looks like the server might be wrong.

Subject: Re: CXF client expects namespace, server doesn't send one.

Are you doing Java first or WSDL first?
An error like this usually indicates that the server or the client is generated against a faulty/changed interface.

Relevant:

This affects compatibility with WSDL-generated interfaces.

This causes an unexpected element error. How can I configure the client to ignore the missing namespace? Plain old java, no Spring.

This LOOKS like the server is generating an invalid soap message.   Any chance of seeing the soap message?  At least the body and immediate children?

Per SOAP spec, the immediate children of the SOAP:Body element must be qualified.  However, it looks like your server is sending back a plain "<getReponse>" element that isn't qualified.  If that's the case, there isn't an easy way to get CXF to use it as CXF would set itself up to generate and accept valid messages.  You MAY be able to use the cxf transform feature (http://cxf.apache.org/docs/transformationfeature.html) to add namespaces to the elements as they come in.   That may work.
