I solve it as below
var Result = serviceRespone.children()[0].children()[0].children()[0]
but is this valid for any response ???

Thank you for this class. I was hoping someone could help me out, I’m trying to use the National Forcast Data Feed (http://www.weather.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl) to test.

I’ve been trying to use their functions like “NDFDgen” like this: “ws.NDFDgen(done, “60302″, 0 )” but I get an error: “TypeError: Error #1006: NDFDgen is not a function.”

The webservice connects but I can’t call any of their methods. I tried to trace out ws.availableMethods[0] (using the availableMethods method in the WebService class) but I get the error: “TypeError: Errpr #1010: A term is undefined and has no properties.”

Does anyone know what I’m doing wrong?

Thanks for your time!

Hi, I’m also getting an error. The availableMethod function returns an empty array because because of the lacking support of xsd:import/external schemaLocation.Is there a way to fix that? That would be geat!

@Justin: The problem is caused by this “” line.

ok, second try, by the line: xsd:schema targetNamespace= …

I have the same problem anybody find the solution?
thank for you help!

Why It is not working if swf and webservice both are kept on different domains. ?? Even i provided the crossdomain.xml file.

The next step, which seems to be causing some of you trouble, is to properly parse the XML using namespaces (its a bit akward, but is well documented. you need to declare a namespace variable and use a different form of addressing to get the data, but once you have it setup its seamless). search for “AS3 XML namespace”

Awesome. Thank you much needed class library!

Hi Carlo, you are a genius! You saved me a lot of days of work, thank u very much.
I want to contribute fot those that doesn’t want namespaces in the resultant xml. I used regular expressions to strip off the unnecessary (and noisy) namespaces like soap, xmlns, and xsi, this is the code, where “xml” is the xml resultant from a web service function:
var re1:RegExp = new RegExp(“xmlns[^\"]*\”[^\"]*\”", “gi”);
var re2:RegExp = new RegExp(“soap:”, “gi”);
var re3:RegExp = new RegExp(“xsi:”, “gi”);
var str:String = xml.toString();
str = str.replace(re1, “”);
str = str.replace(re2, “”);
str = str.replace(re3, “”);
var tempXML:XML = new XML(str);

enjoy!

very cool classes! thx for sharing!

the resolveIP-example works very well.
when i connect to the webservice i need for my project, it successfully connects, but i does not seem to react on any method-call i make. no response at all.

any ideas?

sorry for bad english

Thanks for this awesome class, it’s much better than using the flex one which from memory adds almost 300kb to your .swf. Was wondering if someone could give me some help on handling errors though? for example every now and then if my webservice goes down i get “Error #2044: Unhandled ioError:. text=Error #2032: Stream Error.”… I would like to handle this gracefully in flash. I tried ws.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler) and also putting my webservice function calls in a try / catch block but flash still reports the error as unhandled.

Hi, Thanks for the code
I have a problem, I want to send one variable to webservice not to read, but I cant. in fact I get the error 1080
the error is:
TypeError: Error #1080: Illegal value for namespace.
at alducente.services::WSDL/getPortType()
at alducente.services::WSDL/wsdlLoaded()
at flash.events::EventDispatcher/dispatchEventFunction()
at flash.events::EventDispatcher/dispatchEvent()
at flash.net::URLLoader/onComplete()
I need to send a variable to the webservice using soap, any help?
the variable name must be FileName

Hi Carlo,

I am using your classes and they work very well. I had a problem for WSDL that use the functionality (which is pretty common nowadays) and I modified your code to handle imports. I am not an AS developer and I did not test it extensively, but it works for me. I post it here the functions that I modified in WSDL.as. I hope it helps.

public function WSDL(path:String){
__wsdlPath = path;
__rawWSDL = null;
}

private function wsdlLoaded(evt:Event):void{
var xml:XML = new XML(evt.target.data);

//Handle import
var wsdl:Namespace = xml.namespace();
var xmlImport : XMLList = xml.child(“*”);
var importAddress:String = null;

if ( xmlImport != null ) {
var nameImport:String = wsdl.uri + “::import”;

for each (var element : XML in xmlImport ) {
//element.ignoreProcessingInstructions = false;
if( element.name() == nameImport ){
for each (var attr : XML in element.attributes()) {
if ( attr.name() == “location” ) {
// The statement should be removed before copying xml to __rawWSDL
deleteNode(element);
importAddress = attr.toString();

trace(“Loading import wsdl ” + importAddress);
}
}
}
}
}

if ( __rawWSDL == null ) {
__rawWSDL = xml;
}else{
for each (var child in xml.child(“*”)) {
__rawWSDL.appendChild(child);
}
}

if (importAddress == null) {
read();
}else {
var urlLoader:URLLoader = new URLLoader();
urlLoader.addEventListener(Event.COMPLETE, wsdlLoaded);
urlLoader.addEventListener(IOErrorEvent.IO_ERROR, wsdlNotLoaded);
urlLoader.load(new URLRequest(importAddress));
}
}

private function read() : void {
trace(“final XML ” + __rawWSDL.toString());
var portType:String = getPortType(__rawWSDL);
var bindingType:String = getBinding(portType);
__methodList = getMethodList(bindingType);
__availableMethods = getAvailableMethods(__methodList);
if (__availableMethods != null) {
__parseComplete(__availableMethods);
}

}

private static function deleteNode(node:XML):void
{
// credit to http://edsyrett.wordpress.com/2008/07/26/xmlremovechild/
if (node != null && node.parent() != null)
{
delete node.parent().children()[node.childIndex()];
}
}

Hi Carlo, Just wanted to thank you for creating this and releasing it to everyone! You just saved me an incredible amount of time. Keep up the good work!

Also, put some ads on your blog. You deserve to be paid for this. I would happily buy anything you were selling right now.

nice job, thanks!

@abed allateef qaisi

awesome job! Returns the result of the webservice perfectly!

Thank you so much for the hard work you did on this class. It’s a great framework for how to work with SOAP in flash. I just want to make a note to everyone with questions. Not every webservice is going to have functions like resolveIP as part of their funcitonality. You are going to need to break down the framework here and match it to your development needs.

Thanks again for the hard work!

when connect to the webservice I make by java , it say that “TypeError: Error #1006: sayHelloToWS is not a method . Who can help me?

Hi. Great job.
I need oyur help. When the site thath host webservice is down, or not internet connection, tha call throw an error in getWSDL method in WSDL class.

I try t catch them, with this code block in WebService connect method:

public function connect(wsdl:String):void{
try {
__wsdl = new WSDL(wsdl);
__wsdl.getWSDL(wsdlComplete);
}
catch (error:Error) {
throw new Error(“No se pudo guardar el proyecto”);
}
}

and this code block in my application:

try {
ws.addEventListener(Event.CONNECT, conectado);
ws.connect(“http://www.fotodepot.com.ar/GuardarProyecto.asmx?WSDL”);
}
catch (error:Error) {
popup.CerrarVentana();
popup = new VentanaEditor();
popup.show(‘No hemos podido guardar su proyecto’);
}

Thoes not work. The error still launching and the catch block never is executed.

Can you help me.

Regards.

Alejandro

Hi there,

I’m seeking for a good soap service and your’s seems to be very clean and easy to use. Now i have to connect to a service and the wsdl file is loading perfectly. But there is also a XSD file who is describing the methods and i’m not sure your library supports external XSD files. Can u please confirm this.

Thank you so much!

it is possible to send data?

I want to send me a SOAP server and returns another SOAP, XML is that I will send 20mb, is this possible?

I was having the issue of function not found due to the lacking support of xsd import and what i had to do was as described on this link

http://my-tech-talk.blogspot.com/2008/07/adding-flatwsdl-to-wcf-webservice.html

I basically had to change my WCF service to flatten out the wsdl so there are no imports.

@silverfox: i am sending XML my self to my webservice and they are quite big and it seems to work ok. i have not tried 20 MB yet but will try that.

Hi i am getting error of TypeError: Error #1010: A term is undefined and has no properties.
can you please have a look at my code

import alducente.services.WebService;
import flash.events.*;

var ws:WebService = new WebService();
ws.addEventListener(Event.CONNECT, connected);
ws.connect(“http://localhost:8732/Design_Time_Addresses/TestService/Service1/?wsdl”);
ws.cacheResults = true;

var initTime:Number;

function connected(evt:Event):void{

ws.IBookService.getBooks(done,0,0);
var obj:Array=ws.IBookService.GetBooks();

}

Hi, did you manage to find a solution to catch errors?

My previous comment was referring to Alejandro’s message about connecting when the service is down. At the moment an exception is raised, I would like to handle the error gracefully.
