Send multiple argument to backend method

Question

Dear All,
I am trying to send the multiple arguments to backend server method using Remote Object. At the backend I am using Weborb for .net
private function initWebOrb(event:AppEvent):void
    weborbCallback = event.callback;
var method:String = event.data.method as String;
var data:Array  = event.parameterdata;
var op:AbstractOperation = remoteDataObject.getOperation(method);
op.addEventListener("result", getListResultHandler);
op.addEventListener("fault", onerrorweborb);
op.arguments =data;
op.send();
but It shows the error unable to find method with name "Testmethod"  and the given argument types  at Weborb.Util.MethodLookup..........
I have also tried.
private function initWebOrb(event:AppEvent):void
   weborbCallback = event.callback;
var method:String = event.data.method as String;
var data:Array  = event.parameterdata;
var op:AbstractOperation = remoteDataObject.getOperation(method);
op.addEventListener("result", getListResultHandler);
op.addEventListener("fault", onerrorweborb);
op.send(data);
I also tried to send the data as object
var data:Object  = event.parameterdata;
Note: I change the argument type accordingly while dispatching this event.

               <f:arg value=<%= parameter> type="int"/>
</f:invoke>
