JAXWS marshals null WebParam headers with xsi:nil=true

[Tomas-Kraus]

JAXWS wsimport generate code as follows:

A Header class

@XmlRootElement(name = "MyCustomHeader" ) public class MyCustomHeader

{ ... }

A PortType class with the following method:

@WebMethod(operationName = "AnOperation", action = "AnAction") @WebResult(name = "OperationReply", targetNamespace = "http://example.com", partName = "reply") public OperationReply anOperation( @WebParam(name = "OperationRequest", targetNamespace = "http://example.com", partName = "request") OperationRequest operationrequest, @WebParam(name = "MyCustomHeader", targetNamespace = "http://example.com", header = true, mode = WebParam.Mode.INOUT, partName = "header") Holder<MyCustomHeader> header);

Calling the method as follows:

port.anOperation(operationRequest, null);

Marshalls an XML with the MyCustomHeader as null.

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"> <S:Header> <ns1:MyCustomHeader ... xsi:nil="true"/> </S:Header> ... </S:Envelope>

Any other Web Services framework discards headers passed as null values to the operation.

JAXWS should discard headers which are null.

A workaround is to implement a SOAPHandler to remove the null headers and add it to the handle chain of the port.
