[flexcoders] Re: How to write Flex proxy without data server access and FDS
Mark, Thanks again for your suggestion. Here's what I've got now: I've generated a proxy script (in both .NET and C#) based on wsdl file. The proxy script resides on the same server (IIS) as my SWF file. Now, how do I invoke my proxy script from MXML file? Just out of silliness, I've tried mx:WebService, and wsdl=myProxyScript useProxy=true (also tried useProxy=false) ... This gave me the HTTP request error. I know I should really invoke the web method on proxy script, but I guess I'm just so dumb, that I can't figure it out. Please help!

[flexcoders] Re: How to use Proxy script with Flex WebService?
Peter, Thank you for your post. I've tried your suggestion, but getting the HTTP request error every time I invoke the Proxy. I'm not sure I'm doing it right, but I have the .NET proxy script sitting on the same server my .swf file is. Now, in my .mxml, inside mx:WebService, I set the wsdl=myProxyFile. This results in the above mentioned HTTP error. I see my webservice methods defined inside proxy script, but I don't know how to invoke it from MXML file. I'll probably have to publish it in a new post.

[flexcoders] Re: How to use Proxy script with Flex WebService?
Peter, Thanks for your reply. I've tried the suggested way of invoking webservice thru proxy, but it didn't work. I'm getting the same error: HTTP Request error. Btw, I set useProxy=false since I'm not using FDS. You're abs right, and my SWF file resides on the same domain (IIS server) as my proxy script (I have both JS and C#-dll proxies). The webservice resides on another server (no crossdomain.xml) to which I obviously don't have access. Based on my Java experience, I just need to instantiate the class declared inside the proxy script, then call a web method passing parameters, but I'm not sure how to do it in Flex.

The SOAP address location (usually defined at the bottom of your WSDL in the port section of the service) will also need to be changed so that it goes through your proxy.

[flexcoders] How to invoke WebService via Proxy script?
Hi folks, I'm consuming webservice from a server with no crossdomain file. So, I've generated a proxy script based on wsdl file. The proxy script resides on the same server as my SWF file (I have no access to the data server, and FDS is not an option). Now, in my MXML file, I have mx:WebService, and wsdl=myProxyScript useProxy=false ... define my operation, etc. When I run it, I get the HTTP request error. I know I probably don't do it right, but I'm not sure how else I invoke a proxy script that talks to WebService. I see all the web methods inside proxy script, but I guess I'm just so dumb, that I can't figure it out. Please help! Thanks, /Roman
[flexcoders] Re: How to use Proxy script with Flex WebService?
Osvaldo, Thank you for your post. Unfortunately, your suggestion only works when invoking HTTPService, not WebService. In other words, those proxy samples (php, asp, jsp, etc) I've downloaded from Adobe (http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_16520) cannot handle a WebService call. I was getting either Runtime errors, or errors sending HTTPRequest. It all made sense to me after reading this article: http://www.adobe.com/devnet/flash/articles/flmxpro_webservices_05.htm l. If you read the WHOLE article, it'll tell you what other pieces you need to write a generic Flex proxy script (nusoap.php, Serializer.as, etc) to invoke a webservice from a domain with no crossdomain.xml. I'll post my notes once I get my webservice running.

(that link explains the difference between setting useProxy to true or to false) I had the same situation and I solved it using a proxy.php (downloaded from Adobe) with the final url (the one without crossdomain.xml) hardcoded in it. While instanciating the HTTPService I set the url to the proxy.php location.

[flexcoders] Re: How to write Flex proxy without data server access and FDS
Mark, Thank you for your suggestion. The only feasible option for me would be to write the Proxy script and put it on the same server that hosts swf file (I do have access to that). I'll have to check whether client's IIS server has Cold Fusion or PHP support ... otherwise, my options would be Microsoft scripts (C#, .NET). Btw, do you know of any Proxy script examples on the web?

[flexcoders] Security error accessing url
How to get around this error? I've written small Flex application to retrieve stock info in exchange for company symbol. I've used Eclipse with Flex plugin. Inside the app, I'm calling webservice on quote.yahoo.com website. I can load the html page which references the swf file (by either running it from within Eclipse, or by opening it in both IE and Firefox). This works fine, and I get some stock data back. However, if I try serving the page from one of my local servers, or even copying it (along with other supporting files) to other location on my hard drive, loading the same page results in an Security error accessing url from my Adobe Flash Player 9. I've even tried to use a straight HTTP post instead of a webservice call, but to no avail. Now, I know that in order to access the data on the domain other than the one my app is running on, Adobe Flash Player requires crossdomain.xml file to be on the data server root. Yahoo indeed hosts this file at http://quote.yahoo.com/crossdomain.xml, but it only has a few entries. I simply want to read company stock info from publicly exposed service, but I see no way of adding the domain name to their crossdomain file each time someone wants to read a stock info. Any help is appreciated. Roman
