How to call Operation in Spring-ws

[wadhwapushp]

I am using Spring-Web Service Client to Call Siebel Web Service. Spring-WS creates WSDL operation for all messages that end with the defined request or response suffix.(i.e EchoRequest to Echo operation ).
In my Web service operation Name is = "OrderDetailQueryPage" and request Name is "OrderDetailQueryPage_Input" . By default OrderDetailQueryPage_Input operation is called in by Spring web service client . Which gives me following exception.

org.springframework.ws.soap.client.SoapFaultClient Exception: There is no active Web Service with operation named 'http://siebel.com/OrderManagement/Order/Details:OrderDetailQueryPage_Input'.(SBL-EAI-04313)

I need your help to identify how to specify the operation name in client side (i,e Axis web-service - has Call.setOperation )

Thanks in Advance
