Connect flex to a SAP web service

[Former Member]

Hi all,

I don't have any experience with SAP and I need to make a connection between flex 3 and a web service created from a BAPI, someone have some experience with this??

Thanks in advance

Hi all,

Thanks for your answer Dirk, but I'm still a bit confused with my problem, so I'm going to explain it:

I have a web service based on a BAPI with one input parameter and I need to get a response from this web service (a short string).

So I'm using the following way to call the web service:

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
	initialize="initApp()" width="227" height="67">
	
	<mx:Script>
	<![CDATA[
			import mx.rpc.AbstractOperation;
			import mx.controls.Alert;
			import com.sap.flex.ws.runtime.WSDLType;
			import mx.rpc.wsdl.WSDLBinding;
			import mx.rpc.soap.mxml.WebService;
			import mx.rpc.soap.WebService;
			import mx.rpc.events.ResultEvent;
			import mx.rpc.soap.LoadEvent;
			import mx.rpc.events.FaultEvent;
			import mx.collections.ArrayCollection;
			[Bindable] public var msg_txt:ArrayCollection;
			public var WS:WebService;
		
		private function initApp():void{
			WS = new WebService();
			WS.WSDLBinding = "http://xxxxxxx.xxx.xxx.xx:xxxx/sap/bc/srt/wsdl/bndg_DDAB255C416DE1F18AD8001B789FF0AD/wsdl11/binding/ws_policy/document?sap-client=200";
			WS.setRemoteCredentials("user","password",null);
			WS.addEventListener(FaultEvent.FAULT,onWSError);
			WS.addEventListener(LoadEvent.LOAD,onWSDLLoaded);
			WS.addEventListener(ResultEvent.RESULT,onWSGotResult);
			WS.loadWSDL();
                      }
.
.
.
.

but when I test the code I get the following ActionScript error:

Error: Cannot assign operations into an RPC Service (WSDLBinding)

I'm having a problem importing the runtime library from WSDL to ActionScript Proxy Generator for Adobe FlexBuilder too, and I think that these problems could be the origin of my errors.

As I said in my first post, I dont have any experience with Flex and SAP so, can help mesomeone??

Thanks in advance.

Juanjo.

Hello Juanjo,

the URL looks not correct. Do you get the WSDL when you enter the URL in the browser?

In the SAP standard the URL looks like:

http://xxxxxxx.xxx.xxx.xx:xxxx/sap/bc/soap/wsdl11?services=[RFC-name]&sap-client=[XXX];

Hi Juanjo,

see the the following posting:

For using a SAP Service you will need the URL of the WDSL. You get the correct URL by using the WEBSERVICEBROWSER.

Regards

Dirk
