addsimpleHeader

[alrossers]

Fellow devs,

I'm trying to call a web service by passing a SOAP parameter/header to the method, using the following code:

import mx.rpc.soap.*;

import mx.core.*;

import mx.rpc.events.*;

import fl.data.DataProvider;

import com.adobe.crypto.WSSEUsernameToken;

var myWebService = new WebService();

myWebService.addSimpleHeader

("header3", "http://www.w3.org/2001/XMLSchema", "symbol","MSFT");

myWebService.addEventListener("load", loadDone);

//myWebService.loadWSDL("http://www.webservicex.net/country.asmx?WSDL");

myWebService.loadWSDL("http://www.webservicex.net/stockquote.asmx?wsdl");

var myOperation:Operation;

function loadDone(evt:LoadEvent)

{

myOperation = Operation(myWebService.getOperation("GetQuote"));

myOperation.addEventListener("fault", wsError);

myOperation.addEventListener("result", wsResult);

myOperation.send();

}

function wsError(evt:FaultEvent)

{

}

function wsResult(evt:ResultEvent)

{

var xml:XML = XML(evt.result);

Test.text = xml.toString();

}

If I just run that code without dealing with parameter/header (see commented out line), it runs fine.  But when I try to pass in a parameter via addsimpleheader, it always returns "exception".  The web service country.asmx returns all countries; it doesn't need any parameters.  That's the one that works fine, without the addsimpleHeader.  But stockquote.asmx requires you to pass in a parameter, which is why I'm trying to get addsimpleHeader to work.

Any suggestions?

Thanks,

Alan

What I understand is, you want to pass parameter to a SOAP webservice.

If this is right, you don't need headers to pass arguments to a web-method. The operation has a request:Object property that is used to set the arguments to be passed to the service.

For example

var obj:Object=new Object()

obj[parameterName1]=parameterValue1

obj[parameterName2]=parameterValue2

.

.

.

and finally

myOperation.request=obj

This can also be set by the <mx:Request>  .... </mx:Request> within the <mx:Operation /> tag.

Hope this solves your problem.

If you don't mind, may I ask why you are not using DCD wizard to connect to the webService. It is much easier that way !!!
