Using the Flash MX 2004 web service classes

The ActionScript

The following Actionscript is the basic code needed. Hopefully the comments make the code self-explainitory. The next example will include lots of debugging and other features.


 import mx.services.*;

/* import all of the webservices class packages. 

Note: if you do not use the above import statement you will have to 

call the web service with the full path (new mx.services.WebService(..) */

                                                                       

// set it up so that the service is called when the button is pressed.

result_btn.onPress = function() {

    

    // Create a new instance of web service called - stockservice.

    var stockservice = new WebService("http://www.flash-db.com/services/ws/companyInfo.wsdl");



    // Call the doCompanyInfo method and assign it to the pending call object to handle results.

    stockResultObj = stockservice.doCompanyInfo("any","any","macr");

    

    stockservice.onLoad = trace("loading");

    

    // the onResult function is called if the service is successful

    stockResultObj.onResult = function(result) {

    

        // example result values.  The result is a decoded actionscript object

        //version of the xml returned by the operation.

        // In this case the result is a object with company, lastPrice etc being properties.

        trace("company Name: "+result.company);

        trace("lastPrice: "+result.lastPrice);

        trace("volume: "+result.volume);

        trace("yearHigh: "+result.yearHigh);

        trace("yearLow: "+result.yearLow);

        

    }



    stockResultObj.onFault = function(fault) {

        // If there is any error such as the service not working, the onFault handler will be invoked.

          trace(fault.faultCode + "," + fault.faultstring);

    }

}

To test, copy the above actionscript and place on the first frame of your movie. Then 'Test Movie'. The output window should display something like:

loading
company Name: MACROMEDIA INC
lastPrice: 26.95
volume: 1676392
yearHigh: 28.80
yearLow: 6.00

So the above code works well and is fairly easy to use, but what about if you need to debug or more closely follow the interactions of a more complicated web service - we'll get to this on the next page.
