Dose javax.xml.rpc.encoding.XMLType has anything to represent void type

Question

Hi All,
Is it possible to use XML types to represent a void(type).
In other words, dose "javax.xml.rpc.encoding.XMLType" has anything to represent void type.
Here is my code snippet...
At the Service Endpoint i have a service
  public void invokeBatchProcess(String actType)
    throws   java.rmi.RemoteException; At the Web-Service Client side i'm invoking this webservice using DII.
Not sure how to set the return type to Call object.
Client Code:
ServiceFactory serviceFactory = ServiceFactory.newInstance();
//Service Name
Service service = serviceFactory.createService(new QName(
          IConstants.DEFAULT_SERVICE_NAME));
//Port Name
QName port = new QName(IConstants.DEFAULT_SERVICE_PORT);
Call serviceCall = service.createCall(port);
serviceCall.setProperty(IConstants.URI_ENCODING_PROPERTY,IConstants.URI_ENCODING);
serviceCall.setProperty(Call.SOAPACTION_USE_PROPERTY,new Boolean(true));
//Target EndPoint
serviceCall.setTargetEndpointAddress(IConstants.DEFAULT_URL);
//OperationName
serviceCall.setOperationName(new QName(IConstants.DEFAULT_SERVICE_OPERATION_NAME));
serviceCall.addParameter(
"arg1",new QName("http://schemas.xmlsoap.org/soap/encoding/","string"),
ParameterMode.IN);
//How to use XMLType to represent void ???
serviceCall.setReturnType(????????) Greatly appreciate your help.

Hello-
Sorry for the delay in responding.
Given the following dii client you will not that the return parameter does not need to be set on the call object-
The call is invoked in the normal way using the invoke method-
the invokeOneWay method performs calls asynchonously and no soap message is returned to the client-
The client below that has a void return parameter does
deserialize a soap response message, but the message contains no data.
public static void main(String[] args) {
try {
ServiceFactory factory =
ServiceFactory.newInstance();
Service service =
factory.createService(new QName(BODY_NAMESPACE_VALUE,qnameService));
QName port = new QName(BODY_NAMESPACE_VALUE, qnamePort);
Call call = service.createCall(port);
call.setTargetEndpointAddress(endpoint);
          call.setProperty(Call.SOAPACTION_USE_PROPERTY,
new Boolean(true));
call.setProperty(Call.SOAPACTION_URI_PROPERTY, "");
call.setProperty(ENCODING_STYLE_PROPERTY, URI_ENCODING);
               call.setProperty(Call.OPERATION_STYLE_PROPERTY, "rpc");
                    HelloClient client = new HelloClient();
                    client.sayHelloNoReturn(call);
} catch (Exception ex) {
ex.printStackTrace();
     void sayHelloNoReturn(Call call1) {
try {
          call1.setOperationName(new QName(BODY_NAMESPACE_VALUE, "sayHelloVoid"));
          boolean b = call1.isParameterAndReturnSpecRequired(
     new QName(BODY_NAMESPACE_VALUE, "sayHelloVoid"));
               if(true) {
                    //call1.setReturnType(new QName(NS_XSD, "string"),
                    //          java.lang.String.class);
                    call1.removeAllParameters();
                    call1.addParameter("String_1", new QName(NS_XSD,
                         "string"), java.lang.String.class, ParameterMode.IN);
                    Object[] params = { "foowho" };
                    call1.invoke(params);
} catch (Exception e) {
     System.out.println("Caught exception: " + e.getMessage());
e.printStackTrace();
The following is the message that passes from the dii client to the service, and the service response-
