Henry, Thank you for the detailed answer. I figured that it must be the Flash sendAndLoad that limits the SOLO application in this respect.
I finally got around to testing my web service on IIS. I'm having some trouble sending SOAP messages to the service with my SOLO application, and I'm not sure what the source of the problem is. Calls to simple ASP files work fine, as does loading a static XML file. But calls to the web service fail. I suspect it could be because of the stuff Laszlo adds to the POST request. The request for the WSDL at http://localhost/TestClass.asmx?wsdl failed as well, because Laszlo added some parameter to the url, but I got around that by creating a virtual directory which redirects the call and loses the parameter. That worked well with GET method, and I receive the wsdl xml without problems. The SoapAction header should not be the problem, as I've configured the web service to use the first element inside the body tag as the method name. The SOAP request I've used to test the service: <?xml version="1.0" encoding="utf-8"?> <soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema"; xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/";> <soap:Body> <Test xmlns="http://tempuri.org/"; /> </soap:Body> </soap:Envelope> The code I use to send this request: var xmlHttp = new XMLHttpRequest(); xmlHttp.open("POST", "http://localhost/TestClass.asmx";, true); xmlHttp.onreadystatechange = function() { if(xmlHttp.readyState == 4) Debug.write("Response received."); } xmlHttp.send(soapRequest); // this sends the XML This is the error I get: WARNING: rpc/ajax.lzx:209: call to undefined method 'isProxied' WARNING: LzLoadQueue.serverlessOnDataHandler load failed from URL 'http://localhost/webservices/TestClass/TestClass.asmx': no data received Failure to load data in serverless apps may be caused by Flash player security policies. Check your data server crossdomain.xml file WARNING: rpc/ajax.lzx:169: call to undefined method 'isProxied' Any help is greatly appreciated!

Looking to the future, the DHTML runtime uses XMLHTTPRequest, and so provides somewhat better HTTP controls, and the Flash 9 runtime looks a lot better in terms of support for HTTP network operations which are closer to what you get from the java.net API. It is actually possible to send raw POST data I believe, if you use the XML object in Flash instead of the LoadVars which is used by the system currently, but it would be somewhat difficult to work into the existing loader machinery. The major complication in the loader system is due to the fact that we have to implement our own loader queue because Flash silently drops requests that are made when the browser's maximum number of network connections are opened. So for example if your app happens to be loading an image or other data resource, your code cannot just make a request safely. Internet Explorer has a maximum of 2 open connections available to each web page. Anyway, I could suggest some workarounds if you really want to pursue this, otherwise I suggest writing a little server side proxy that your app communicates with, that can handle all the SOAP HTTP protocol issues, and return just the XML that you want. _______________________________________________ Laszlo-user mailing list [email protected] http://www.openlaszlo.org/mailman/listinfo/laszlo-user
