Hi Ekki,
I would also like to catch WSDL availability - no success yet.
For now I just created timer:

Code:

        SC.showPrompt("Reading WSDL...");
        XMLTools.loadWSDL(wsdlAddress+".wsdl", new WSDLLoadCallback() {

            public void execute(WebService webService) {
                wsdl = webService;
                SC.clearPrompt();
            }
        });
        // Create a new timer
        Timer t = new Timer() {

            public void run() {
                if (wsdl == null) {
                    SC.clearPrompt();
                    SC.say("Some error message");
                }
            }
        };
        // Schedule the timer to run after 5 seconds
        t.schedule(5000);

ps
Where do you get SC run-time error ? What I can see is in the Developer Console log only and callback is never executed.

Timers are ugly. For that you should use Callbacks! The only concern I have is that SC error msg - one for each WSDL Service Description that couldn't be retrieved... This is I need to avoid. No matter if the server is up or down, no native error msgs should appear

Yes I know that callback should be used, but in my case it is not executed when wsdl is no available and I have no other way to clear prompt and print the error message.
I got the following in the Developer Console only:

Code:

It seems to me that XMLTools.loadWSDL() completely ignores RPCManager.setHandleErrorCallback() so it is not possible to catch error this way.
As partial workaround could be fetching wsdl (just to check if it is available and readable):

Code:

        RPCManager.setHandleErrorCallback(new HandleErrorCallback() {

            public void handleError(DSResponse response, DSRequest request) {
                    SC.say("Some error");
            }
        });

        //  WSDL exist ?
        DataSource testDS = new DataSource();
        testDS.setDataFormat(DSDataFormat.XML);
        testDS.setDataURL(wsdlAddress);
        testDS.fetchData();

        XMLTools.loadWSDL(wsdlAddress, new WSDLLoadCallback() {

            public void execute(WebService webService) {
                wsdl = webService;
            }
        });

If there is a better way, please let me know.
Thanks,
MichalG

Make a visual state info, set it initially to Bad and change it to Good after availability of the service. Alternatively, disable the GUI functionality on some global level, and enable it accordingly. Sometimes the GUI even doesn't make sense w/o availability of the services.

No timers for that pls as it's theoretically impossible to define the optimal time out value ;-)
