Pragmatically Reload WSDL for WebService

Question

Hey everyone,
I'm new here and i'm starting to try out RIA. I'm currently
working against a little test web service. Pretty simple and trim.
Here's my problem.
I want to seemlessly handle when the web service goes down.
The senario is like this:
1.) WebService goes offline at the web server.
2.) User executes an operation with returns with a ioError
fault.
3.) This error is captured and identified as a
"Disconnection"
4.) Now the user is presented with a modal popup informing
them the web service is down.
5.) A time was started that will test if the web service is
online at a set interval.
6.) When the service is back online, the modal popup is
removed, and the user can continue with their work
My reconnection code is pretty simple. It's:
myWebService.disconnect();
myWebService.loadWSDL();
My assumption is that when you execute the loadWSDL, it will
go out to the server and attempt to download and reload the WSDL.
There is a fault capture on the main webservice so i can detect
when the loadWSDL fails. If it fails, the webserivce is offline so
i keep the modal up. If the loadWSDL can be loaded, the "load"
event is fired for the webservice. I detect this event and remove
the modal popup.
However, the loadWSDL does not go back to the server. It
detects that it has already been loaded, and fires the "load" event
for the webservice.
So my main goal here is to have a way to test if the
webservice is online. I *could* develop a simple webservice
function that simply returns a string if it's online. But i want to
avoid having odd calls like that in my webservice. There has to be
a way you can do this.
Any help would be hugely appreciated.

Answer 1

Still looking for a response on this. So far we've
implemented a webservice call to check if the webservice is active.
But i'd be interested if there's an answer.
I'm hopeing the answer will help me understand why the
WebService object needs to download the WSDL everytime in the first
place.
