Flex :: Client / Server Messaging (RPC Or Socket)
Apr 9, 2010
I'm building a Flex application, which is going to perform many server requests (let's say, that almost all interactions require an update from server). At the moment I'm using remote procedure calls for it. But I was wondering if using a socket would be better. In other terms, is maybe better to keep the connection alive rather then performing many calls in sequence? For my demo app I only have 1 client. Is the number of clients connecting to the server a factor for this choice?

I have designed with Adobe Flash Professional CS5 a .fla project that integrates a client - server connection. After publishing it, I have the following issue:- when running the generated .exe file for Windows, then the connection to the server works perfectly- but when I am running the published .html file, then nothing is sent to the server.
I have tried to change the Publish Settings. When setting the Local Playback Security in Flash menu to "Access network only" instead of "Access local files only" then the last packet that was send using the .exe file is resent once and that's all (the html client does not receive the response from the server and the next connection attemps generate data transfer). I guess I have to change some security settings somewhere but I didn't find which.

I have a flex UI which communicates with server using spring blazeds. I have a very typical requirement of Live data streaming on a panel in UI. Requirement is like this, We have an object say, Person and server keeps pushing its data on blazeds message destination where UI panel consumer has subscribed and hence user can see this live data in a panel. User can open multiple panels in same browser to view data for different Persons at the same time (e.g id=1,2,3 respectively). There can be multiple UI users who may be viewing the same data for person id=1 at a given time, lets say.
Basically I want to separate data between UI panels. UI panel opened for person id=1 must not display data of that for person id=2. I am doing this using headers-selectors, but apparently I found out that the differentiation to select and display what data happens on UI which is causing performance issues. I learned that using subtopics may improve performance. But, before proceeding for it, I want to know, will UI browser end up in receiving data irrespective of subtopic assigned to data and then consumer will decide to accept it or not?

We're writing a flash application that can download a MP3 file, convert it to a Sound object, get the raw data and make some processing (like adding sounds, change octaves). After the processing, we want to send the data back to the server in chunks, so the server will be able to glue the data together and recover the new generated file. The problem is: if we send to the server "wav" pieces of sound, we are able to glue them together without any problem in the generated file. However, if we convert each wav piece to a mp3 file (so we can send a smaller file to the server) and join the mp3 files at the server, the result is a sound with some problems at the merge point.
This is how we load the mp3 file from the server:
sourceSnd.load(new URLRequest("sample url to mp3"));
sourceSnd.addEventListener(Event.COMPLETE, carregou);
This is how we convert each piece of mp3 to bytearray and wav:

I am writing a online game with flex and java server and I have a big problem. In normal case, my game run smoothly but some time the clients can't receive the command from server. I found that if server send message too fast or client is doing something when server send message, the game client can't detect for a new message so my game is freeze. I only tested with 4 clients and I don't know what happen when thousands clients online in the same time. So terrible :(. In the game client, I use one EventDispatcher class to dispatch any command from the server. Do you have any solution to warranty that client must receive any message from server when the connection is still alive or server must know if client received the message or not. I use flex 3 with Socket (binary) and Java QuickServer.

I'm trying to get my Flash application to connect via socket to my server, so I need to set up a socket policy file server. It seems like there are various roll-your-own implementations floating around out there, but is there any kind of standard or best practice with what to use?
As an aside, it seems strange that Adobe imposes this restriction but doesn't make something readily available to support it.

I made sure the playback security was set to network only on the publish settings menu. I have another program that connects to the same server without a problem, so I don't think it's a cross-domain policy file problem.

Ok, basically my Flex app will open up a socket and listen on it. My java program will write some string to this port.
My AS3 code is
private function onRecvClick():void
{
var host:String = "localhost";
[Code]....
While trying to write to the socket, i am getting this java.net.ConnectException: Connection refused: connect. Funny thing is that the socket in Flex doesn't seem to dispatch any events, is it normal for that to happen?

I am attempting to use an online Flash file to communicate and pass data to a device linked to a client machine.I have got the Flash to work using sockets and when run from the same machine as the device it works fine.However, the flash file needs to be online and I need a way to allow the data to be passed. At the moment it won't connect to the socket on the client machine (I just get a connection failed message after about 10 secs) and I believe that this has to do with the security settings.
I am looking into Cross Domain Policy files as a way of securing the connection, but all of the information present suggests that these are only applicable to server machines. Can I put a Cross Domain policy file on the client machine that would allow the online flash to access one of it's sockets or will a CDP file on the server hosting the flash file be able to allow access to a client machines sockets?

I've read some books on creating stateless websites, I've read some about stateful client applications, but a lot of complexity comes along when you have to combine both. We have a Flex application that needs to persist data to a database via .NET services. Things to keep in mind are:
- Concurrency (optimistic/pessimistic)
- Performance: Flex needs to load in lots of data so lazy-loading is often necessary.
- Do you use Dto's to transfer data between server and client?
I'll tell you the history of our product. We've used SubSonic from the beginning as a o/r mapper. SubSonic objects are converted to dto's written by us and these dto's are transferred to the client. Clientside the dto's are converted to the domain model. If clientside a domain model object needs to be saved, it is converted back to a dto and send to the server. Server side the dto is converted to a subsonic object and saved to the database.
Now, some time ago, we needed the domain model on the .NET server side... so now we have like three models on the server side, the subsonic model, the dto model and the domain model. The dto model is more simple and resembles the database more, the domain model has much more logic. It gets complex... We now have to synchronize the AS3 domain model code with the C# domain model code. If we could do it again (of get time to refactor) I think we wouldn't use the dto's anymore, but transfer the domain model between client and server. Dto's are simple objects so easy to transfer. Domain model objects can be very complex.

I have created a client with Flex Builder which works in a browser but also in an Air windowed application. I must connect it to a server and it has to do asynchronous request related to changing data of the server.Because of the too much expensive cost of LiveCycleDS license, I was looking for other ways, maybe open source and i found the following solutions:
Adobe BlazeDS
Granite Data Services
WebORB Community Edition
I want to ask you which is the easy way to create the solution described above, expecially i want to use J2EE application server type.

As far as In understand the Flex technology, a Flex client connects to a Flex server to retrieve business information. Is this the only allowed connection for the client, back to the originating server? Or can a Flex client also open a secondary connection to a different server wich runs BlazeDS for message exchange?(This might offer an option for load balancing and cross-platform development).
Update: I have found this page which links to the Cross-domain policy file specification:[URL]..

But what I want to do is to read the file from client and parse it without uploading it to the server.

I'm a new grad, so please be kind. I'm working on validating input in a Flex DataGrid cell that the user can edit. The rows in the DataGrid are backed by an mx.collections.ArrayCollection that includes a [Bindable]Model that I wrote. I want to validate against a custom client-side Validator, if-and-only-if that passes I want to validate the input on the server. If client-side validation fails, I want to display the normal validation error (see image below). If server-side validation fails, I want to use the same sort of UI components to notify the user. The solution should not include any external framework (Cairngorm or PureMVC).
[Code]...
How do Flex programmers validate on the server, immediately after the valid client-side validation passes?
I realize it seems silly to search out this "synchronous" design and I hope someone has an answer to solve my problem with best practices. In my defense, the reason I want to validate on the server immediately following client-side validation is so that I'm using Flex's validation framework. If I get an invalid response from the server, I want to leverage the built-in UI components that Flex has to tell the user something is incorrect about his/her input.
