Deserializing Long[]

[James Kojo]

I have a webservice method that is supposed to be returning an
array of type Long[]. For some reason, the return value
is not coming back from the call.invoke() method as a long.
I checked the class type name, and the response object is of type:

org.apache.axis.encoding.ser.ArrayDeserializer$ArrayListExtension

Here's the calling code:

    Call call = null;
    Object response;
    QName operation;
    QName outputQName;

    operation = new QName("ICMEngine", "getTargetIDs");
    outputQName = new QName("ICMEngine", "ArrayOf_SOAP-ENC_long");

    try
    {
      call = (Call)service.createCall();
    }
    catch( ServiceException se )
    {
      throw new IMClientException("IM_CLIENT_SERVICE_ERROR", se);
    }

    //
    // Initialize the Call object
    //
    call.setTargetEndpointAddress(serverURL);
    call.setOperationName(operation);
    call.addParameter("target", XMLType.SOAP_MAP, ParameterMode.IN);
    call.setReturnType(outputQName);
    call.setOperationStyle("rpc");
    // call the SOAP service
    try
    {
      response = call.invoke(new Object[] {target});
    }
    catch( RemoteException re )
    {
      throw new
IMClientException("IM_CLIENT_REMOTE_METHOD_INVOCATION_ERROR", re);
    }

    if( response instanceof Long[] )
      return((Long[])response);

    return(null);

Do I need to explicitly convert this type? If so, then how?

Thanks,

James
