hi

I'm a novice coder, and am trying to get flash to connect
to a webservice. I think I've got the connection :-) but
am unable to view the info, and after viewing various
tutorials and forums and completely stuck.

I have attached the fla which I hope will help.

And below the actionscript alone.


Thanks

hi your flash file is not attached.
are you using AS3 or AS2? are you using any existing component or classes?

I havent done anything where Flash connects straigh to a SOAP service but I figure if it gets too tricky you could write a server side proxy script to handle the SOAP communication and then use a more AS3-supported data format between your server and Flash. Most server side languages have native (or add-on) support for SOAP, and it should be a pretty straightforward process to send and recieve envelopes. As a bonus, you may also control (server-side) who is authorized to use the data, if ever needed.

You probably already read it, but a quick googling resulted in this:
http://vevmedia.net/blog/actionscript-3-and-soap-webservices/

It looks like AS3 and SOAP works quite well, even though it seems (only scanned through results briefly) it is more of a workaround than a real solution since AS3 XML doesnt really like namespaces.

Good luck!

xml in AS3 uses the ECMAScript Specs - hence  E4X so you can handle namespaces.

I use SOAP services on a daily basis with flash, but in order to point the asker to the right direction, need to know what he's currently doing.

hi  experts :-)

sorry the actionscript and fla seem to have gone?
Here they are again.
 
UKJackpot.fla  
import mx.services.WebService;
import mx.services.PendingCall;
function WebServiceCall(input:String) {

var outputField:TextField
var returnedValue:String;
var wsURL:String = "http://www.virtualworlddirect.com/elotterywebservice/lotteryservices.asmx?wsdl";
var ws:WebService = new WebService(wsURL);
var re:PendingCall = ws.LotteryGetAllDetails(UKJackpotEstimate);
re.onResult = function(result):Void {

returnedValue = result;
outputField.text = result;
trace("Jackpot is "+returnedValue);
callback = ws.LotteryGetAllDetails(UKJackpotEstimate);
callback.onResult = function(result){
      trace("result obtained");
      trace("result: " + result);
      TextField_txt.text = result;
}

};
re.onFault = function(fault) {

returnedValue = fault.faultCode+","+fault.faultstring;
{
   trace("fault.faultcode= " + fault.faultcode);
   trace("fault.faultstring= " + fault.faultstring);
   trace("fault.detail= " + fault.detail);
   trace("fault.element= " + fault.element);
   trace("fault.faultactor= " + fault.faultactor);
   trace( "-------------------" );
   trace( response );
}
trace(returnedValue);

};

}
// show UKJackpotEstimate”
WebServiceCall(UKJackpotEstimate);

hello. where is UKJackpotEstimate declared?
I swapped out to one of my webservices and it works fine so i'm thinking

1. UKJackpotEstimate value ... check that - tried hard code an expected value - see what happens.

thanks blue-genie, I'm glad to know it connects. :-)
I don't understand what/ you mean 'where is UKJackpotEstimate declared'
or where to hard code an expected value?

you have this

ws.LotteryGetAllDetails(UKJackpotEstimate);

and  

WebServiceCall(UKJackpotEstimate);

what is UKJackpotEstimate??? I don't see it in your code snippet.

That is in the http://www.virtualworlddirect.com/elotterywebservice/lotteryservices.asmx?wsdl file.
LotteryGetAllDetails is the section and UKJackpotEstimate the figure I'm trying to view.?

as far as I know, that's not how it works. unless there's a short cut no one told me about.

you call the function you want

in this case LotteryGetAllDetails .. i can't access it remotely to check if that expects any parameters.

you then get the data back, depending on how the webservice was done. we usually use xml, then in flash i take the xml and parse it to get the value i want.

I don't have access to change the webservice.
Is there a different way I can show the UKJackpotEstimate
from http://www.virtualworlddirect.com/elotterywebservice/lotteryservices.asmx?wsdl 
you mentioned as3 ECMAScript earlier, is this a different way?
or will I need to contact the developers and get them to
change the service to xml?

if you have access to the developers, just find out what if any parameters are expected.
try calling the  method without any parameters.. if you connect successfully just trace the result to see what format it is in.
