RE: [flexcoders] Re: Embedding WSDL?

In Flex 1.5, I was able to preload/embed wsdl into the swf by overriding the sendAndLoad method of the native XML object…

 

Take a look at my blog posting here to see how: 

https://www.cynergysystems.com/blogs/page/andrewtrice?entry=override_native_object_methods_in

 

I don’t think that this exact syntax will work in Flex 2 b/c you can no longer modify the prototype of a native object.    In Flex 2, you could try extending the WebService object like this (although I have no guarantee that this would work… I have not actually tried it).  Use the EmbededWSDL class instead of the WebService class.  You might also need to override the loadWsdl function.

 

package

{

            import mx.rpc.soap.WebService;

 

            public class EmbededWSDL extends WebService

            {

                       

                        public function EmbededWSDL(){

                                   

                                    this.wsdl = "MY WSDL STRING";

                                    super();

                        }

                       

            }

}

 

 

Hope that helps!

-Andy

Kelly,

As Matt observed, I'm using a single AS class (Cairngorm ServiceLocator) for webservice calls.  It's based on Jeff Tapper's DataManager class:

http://jeff.mxdj.com/as3datamanagerfix.htm 

I changed the logic to get the wsdl, when the application loads, to cut a few seconds off of the initial data call.  It appears that once the wsdl is loaded, the webservice doesn't request it again for subsequent calls.  If all of your calls are to the same webservice, there would only be one request for the wsdl.  This would address your client's concern about network traffic.

-TH

Note: You don't have to use AS.  The same thing can be done with mxml.
