how to pass a null value to a wrapped parameter in consumer mode

[Raffaele Spazzoli]

Hi,
I have a java first use case with a document literal wrapped service.
Here is a part of the annotated service:

@WebService(name="AlarmIRP",
targetNamespace="http://AlarmIRPSystem.AlarmIRP";)
@SOAPBinding(use=SOAPBinding.Use.LITERAL,
parameterStyle=SOAPBinding.ParameterStyle.WRAPPED)
public abstract interface AlarmIRPOperations

...

@WebMethod(operationName="acknowledge_alarms")
  public abstract Signal
acknowledge_alarms(@WebParam(name="alarm_information_id_and_sev_list")
AlarmInformationIdAndSev[] paramArrayOfAlarmInformationIdAndSev,
@WebParam(name="ack_user_id") String paramString,
@WebParam(name="ack_system_id") StringTypeOptWrapper
paramStringTypeOptWrapper, @WebParam(name="bad_ack_alarm_info_list",
mode=WebParam.Mode.INOUT) Holder<BadAcknowledgeAlarmInfo[]> paramHolder)
    throws AcknowledgeAlarms, ParameterNotSupported, InvalidParameter;

...

Before creating the service I set the following service factory
properties:


endpointFactory.getServiceFactory().setAnonymousWrapperTypes(true);
endpointFactory.getServiceFactory().setQualifyWrapperSchema(true);     
endpointFactory.getServiceFactory().setWrapped(true);

The generated schema for the wrapped parameter is the following:

    <xs:element name="acknowledge_alarms">
        <xs:complexType>
            <xs:sequence>
                <xs:element maxOccurs="unbounded"
name="alarm_information_id_and_sev_list"
type="ns1:alarmInformationIdAndSev"/>
                <xs:element name="ack_user_id" type="xs:string"/>
                <xs:element name="ack_system_id"
type="ns2:StringTypeOpt"/>
                <xs:element maxOccurs="unbounded"
name="bad_ack_alarm_info_list" type="ns1:badAcknowledgeAlarmInfo"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>

If, in consumer mode, I pass a null value to the
Holder<BadAcknowledgeAlarmInfo[]> paramHolder parameter I get a marshall
exceprion:

java.lang.NullPointerException
        at
it.imolinfo.jbi4corba.jbi.cxf.OutMarshallerHelper.marshal(OutMarshallerHelper.java:141)

I'm using CXF version 2.1.4.

First of all is this behaviour correct? Secondly what modification
should I do to the annotations or service configuration to allow null
values to be passed?

thanks
