.net :: Create WCF Services That Can Be Consumed By Flash?
Jul 22, 2010
I'm a beginner in WCF, which I have chosen instead of Web Services because all articles and blogs I've read seem to point out that ASMX is old news.I have read a bit about the differences between old Web Services and WCF, and I got the general idea. I also took the MSDN WCF tutorial which seemed simple enough.My problem is that I want to create WCF services that can be consumed by Flash. I've read that it's doable everywhere, but with no obvious A-Z tutorial on how to proceed with the server-side and client-side...
my team is building a game in flash to be embeded in a asp.net application.When the game is over the player have the chance to type his name to save his score.This is done using web services called from flash. The webservice receives the name and score.Since the webservice is publicly available how can I make it only callable from my flash given the following conditions:The .swf is hosted by the same asp.net application There are two domains that can access the same application (I have run previously into cross domain issues).Using SSL is not an option. The webservice has to be consumed by the .swf file.
I am new new to flex development.I am building a flex application which uses rest APIs. Right now I have created different for different API calls (login, logout, search etc.) And all these services are in main mxml application file.I am wondering if I can create a separate mxml file like services.mxml that I can use to call any service.
I'm trying out the FlasBuilder ide with ColdFusion 8 on OS X. When I try to create a new project, I get stuck at the server setup screen that forces you to validate your paths for your ColdFusion root folder and your webroot. Every combination I try says either "LiveCycle Data Services is not installed at the specified location" or "Invalid root. The WEB-INF/flex folder must contain either flex-config.xml or services-config.xml." The flex-config.xml file is sitting in that directory. Is there some trick to getting this to work?
According to Cairngorm architecture, we always have a fault handler in every command class for each service.How we can create a single Class for handling Fault handler event for all the services.
I've recently started using FDT, for a while I was using FlashDevelop, it had a really handy feature in Compiler options where you can set UseNetworkServices to false which would stop the compiled swf from connecting to the internet and became very useful for running standalone flash apps without security warnings when loading in an external xml file etc.
I know most people hate 100% flash-based websites, but I was recently forced to use flash for a college assignment. After creating a fully-featured ria in less than 2 weeks with every feature I could imagine, i've regrettably fallen in love with this beast (which I previously refused to touch with a stick) due to the power of AS3 and the ability to sprinkle it everywhere :-
I now want to port a commercial desktop application of mine (which has been largely unsuccesful) to the web and feel flash/flex is an excellent candidate. While creating a html/css/js version would be ideal (working browser shortcuts, for a start), i'm certain it'll take a year to create in cross-browser html/css/js what would take just ~3 months in flash. Obviously as the (paid) desktop product was unsuccessful, i'd want to minimize the risk/investment in the (free) web application.
I plan on using JSON for web services, so it shouldn't be a huge pita to port in the future.Is this a good strategy for launching a web app you're not yet 100% committed to? Or will the fact i'm using flash doom me from the start? Has anybody else done this? If so, how did your userbase respond to the 100% usage of flash, and did you get around to porting it to standard web technologies?
What would be the best way to secure .net web services used by a flex application (both desktop and browser) that requires login? I thought about requesting the user and password in every method of the web service, and having them stored as variables in the flex app, but I don't feel like this is the most elegant way.
I am using Flex/Flash to build a UI which front-ends my Rails server application. I am using WebORB as the communication mechanism. My question should apply beyond just WebORB, however. (I think).
Specifically, it has to do with the services-config.xml file. I have a local (laptop) dev environment, a remote dev and a remote production environment. I am sick of editing the URL in the services-config.xml file, rebuilding and deploying every time I want to test in a different environment.
[Code]...
By setting the URI="/weborb" and giving it a relative path, I figured it would work. locally--but it doesn't when I deploy it to my remote dev and prod environments (Heroku). Weird.
I am using the web services connector but it only works if I set the publish settings to compile for Flash Player 7 or above and I need my movie to run on version 6. The web services connector should work from version 6 and I have used it before and published for v6 but for some reason the movie will publish without an error but the web service won't trigger. If I change the settings to publish for version 7 or 8 then it works fine. Here's my code if it's any help:
ActionScript Code: import mx.data.components.WebServiceConnector; var webServiceURL:String = "http://myurl.com"; var wSCheckConnection:Object = new Object();
I've been trying to set up an instance of Flash Media Interactive Server on Amazon Web Services for an AVChat (avchat.net). I signed up for the service here:[URL] I have some simple questions on getting it started --- namely: do I create the FMIS instance myself now that I've signed up, or do I need to go ahead and create it? I see under the EC2 tab I can create an instance under 'Community AMIs' for adobe-flashmediaserver-useast/fms-4.0.1.8011-centos-5.5-ami-1.manifes t.xml Is this what I want? I realize this is a bit of a noob question.
once installed what I'm trying to do is to add a folder for AVChat into /opt/macromedia/fms/applications/ ([URL]). I am assuming that once I do have this instance running, I can move/modify files on the server instance.
I have just started using Adobe Flash Media Server on Amazon Web Services. Does anyone know how can I monitor server statistics such as the number of active connections? I have connected using SSH to the server but I cannot know what to do from this point on?
Context : I'm working on a Flash application developed with FDT and compiled with Flash CS4 (I need a huge library). It should connect to various Weborb services.Weborb is properly configured. My services are properly executed, and values returned, via the management console. Weborb examples as well as various tests compiled with Flex are fully functionnal.
Problem : when I try to adapt the code to compile with Flash, and setup the remote object like this :
var remoteObject = new RemoteObject(); remoteObject.destination = "GenericDestination"; remoteObject.source = "MyServices.MyService";[code]....
Question: how to properly setup a RemoteObject to connect to a Weborb remoting service from a Flash application compiled with Flash ?
I've (actually my classmate) got a problem with loading local ZEND_AMF services on Windows 7 (XAMPP). I can't find any answer on Google or on Stackoverflow. I found one similar topic without any answers: ActionScript 3 AMF Zend fails silentlyLet me describe the problem: I've developed the UI and dataloading for a Memory(matching) Game in FLASH CS5. The games uses data from an ZEND Framework website (you can add levels/cards/images there).[code]Everything works fine on my Macbook Pro (Using MAMP as local server), but a classmate (who's helping with it) of me that is using a Windows 7 laptop with XAMPP doesn't see anything. We're both using Flash CS5.5.For some reason his Flash isn't able to load local services. When he uses the same URL path like me Flash doesn't do anything in the responder. No Error function call and No Complete function call. We've been searching for the cause and tried several things.In a ZEND_AMF tutorial on the Internet we've found an online AMF Service and put that in the code. Of course we're using a nonexisting service function so the responser will call the Error function. And yes, this works. He runs the function returnError(). The cause of this problem is obvious: Flash on my classmates PC (using XAMPP) won't load local services. Allowing swf to correspond with non-local URLs (is an option where you have to add your swf to the Flash settings) => Has happened
When using SOAP web services in Flash Builder, I am able to use the web services tool and test making service calls without any issue.I can pass strings that contain spaces, double and single quotes with great success. when I write code to send a string containing spaces or quotes, the web service doesn't return a success response.If I remove the quotes and/or spaces, success.I've tried wrapping the string in tags, but I don't know what else to do.
I've done a fair amount of (web)development in the usual MVC way of thinking and it served me well I think. However, I now have to split my application in a way that my front-end has to access the server-side functions as services. Since I'm the one creating the services, I thought I could think of services as controllers which would, in turn, call the functions in my model. Is that a good way to do it? The server side technology in question is PHP and the client-side is Adobe Flex (ActionScript).
I am currently connecting to a Web Service (wsdl) with no problems over HTTP.However as soon as I try to connect over HTTPS, my WebSerrvice object queues up the call and sits there forever.What configuration needs to be done in FMS2 to allow outbound WebService calls to be made using SSL?
I am developing an application with multiple windows, all using their own web services.Is it bad practice to use more than one web service per application? If so, what are the disadvantages?
I have a Java-based server side and a flex client side using Spring BlazeDS Integration. It works fine, but I want to get sound from server side recently. I followed this BlazeDS mapping doc, it says when Java return a Byte[], it will be converted to ByteArray which I want. So I handle the MP3 file by ByteArrayOutputStream, convert it to Byte[] and return it back to front-end, but the value that Actionscript gets turns to be null value.
We have Flex applications that connect to our ASP.NET 3.5 Web Applications and usually download lot of data. Now considering XML as transport, for every item, it transmits meta data twice for example.. instead of transferring int value as <Customer CustomerID=23/> it transmits <Customer><CustomerID>23</CustomerID></Customer> .. now here is where bandwidth conservation becomes an issue.
FLEX Can not read GZip and DEFLATE compressed HTTP Response ( So cant use any of them )I heard of some WSCompression but it requires WSE 3.0 now I am skeptical to introduce too many dependency in my hosting environment which requires too much management and overheads. Is WSE 3.0 only dll library which requires no installation on production server? Does it require rewriting all WebService attribute? Or is it simple one time configuration and more or less, anyone knows does it work with Flex ? Flex dynamically generates web services, and we use lot of its auto generated code, now if we want to support compression then do we need to rewrite lot of code?
Simplest solution I can think of is, reduce unnecessary XML tags and reduce them down to attributes to save bandwidth. Is there an easy way to achieve it, our classes has more then 50-70 properties, I understand it will be nightmare to add attributes to each property but we dont know how to do it in case of SOAP.
I'd like to learn how to create a java web service that can be consumed by a web tier, which is constituted of java and flex. What books can help me learn how to create a java web service and consume it via java & flex?Should I look to build a web service from scratch or from frameworks like: XFire, Axis, CXF, Spring Web Services, etc.?If using a framework is recommended, which of the above or any others makes the most sense to learn/use?
EDIT:Both the java AND flex components of the web tier need to independently access the web service. For example, the flex component helps the user create & save a spreadsheet; the java component retrieves the spreadsheet data and displays it accordingly.
Although iPhone support JSON natively, AMF is a binary protocol and it supposes to use much less bandwidth. Do you think using AMF is a good idea?Just found this AMF library in cocoa (Objective-C):Here's the famous benchmark that shows AMF is smaller and faster than JSON + gzip in Flex:
Today I tried to connect to other domain.I changed url of endpoint, but it looks like flex just ignores my changes.I am sure that an old url doesn't exist in any file in src directory,I even renamed services-config.xml to services-config2.xml, cleaned and rebuilded project many times, even made a release build, but it still connects to the same domain.I have tested flex application in localhost and in the same domain, that has AMF services, but it works in the same way.My services-config.xml is:
We are planning to use flex and Java Web Services, what is the best practice to consume web service from flex is it better to directly call the web service from Action scripts or to use remoting where java client will call the web services and later flex using remoting will the java client?
I have some problem with calling web service from flex. I have service with name UserService with one method string GetData(int i). I want to call this method from flex and get data. My code is here:
protected function application1_creationCompleteHandler(event:FlexEvent):void uService = new UserService(); uService.addEventListener("hello", echoResultHandler); uService.GetData(1);
I'm having a very strange problem around a few services I developed for AMFPHP that worked fine over HTTP but once over HTTPS gone completely wrong. When testing right on export flash IDE the connection goes fine but when online and on the browser it doesn't. On connecting, Flash returns a security sandbox violation like this:
"Error #2048: Security sandbox violation:[URL] cannot load data from [URL]. I know that I'm missing the "www" subdomain on the gateway secure address but this is has another purpose for domain configuration. What's most weird is that even the Service Browser went completely wrong since it tries to open the gateway through the HTTP version of the address instead of the HTTPS one. Upon opening the browser I get a "NetConnection.Call.Failed: HTTP: Failed" error. It also tells me that it's trying to connect to [URL] instead of [URL].
Installed fms4 x64 on windows server 2008 to try it out. When I open up task manager to check processes running, FMSCore process does not run [URL] found this in the knowledge base but step3 "Run this program As Administrator" checkbox is greyed out so I cannot do anything. I have stopped and restarted service so many time, rebooted server at least twice. Even the video that's supposed to play when you click the start screen is not playing.
Set the Flash Media Server services to Run as AdministratorComplete the following steps for each of the following files located in the Flash Media Server root installation folder (C:/Program Files/Adobe/Flash Media Server, by default): FMSAdmin.exeFMSCore.exeFMSMaster.exeFMSEdge.exeRight-click the file and chooseProperties. Select the Compatibility tab and click Change Settings For All Users. Select Run This Program As Administrator. Click Apply, and then click OK. Complete these steps for each Flash Media Server service. Restart the computer. Flash Media Server starts when the computer starts.
