Java :: Flex - Flash Client To Talk To A Server Through A Full-duplex Connection?
Sep 16, 2010My client is in Flash/Flex (game with chat) and it will be talking to a Java server. What is the best way (protocol / interface) for my Flash client to talk to my server? I heard about Flash Remoting MX, but it is a request / response mechanism. I could always request something and wait for asynchronous notifications from server. Then request again, implementing something like a Comet server.Anyways, what is the industry standard for this type of communication: Flash Client talking to Java server, supporting asynchronous "push" notifications from server.

Aug 27, 2010I have Flex/AIR app that connects to a tomcat server via BlazeDS. I'm not finding that I have to integrate an old webapp (struts/jsp) and I'd like to keep that webapp untouched except for login, authentication and session handling. Also a 3rd java app that uses httpclient.
Currently I have some blazeDS remote objects to handle login/logout with a few RPC calls. In turn, FlexSession objects are created and handled. Is there a way to use httpclient and javascript to call those blazeds RPCs so I dont have to recode and have 3 different means to handle logins and sessions?

View 1 RepliesJava :: Encrypt Sqlite Db File With Server Side / So Flex / Air Client Can Read It?
Jan 23, 2012We are trying to create a sqlite db file using java on the server, and encrypt it.Then we send the encrypted db file to a client's pc, which has an Adobe Air desktop app running.The air app then needs to be able to open/read-from the encrypted db file (client is read-only).We are using java 1.6, flex/actionscript 4.5, and Air 3.1.We can create the sqlite db file on the server and send it to the client, and it can be read by the client without issues, when we do not encrypt it.But we are having trouble with the encryption part. We've read quite a lot of documentation about Actionscript's ability to open encrypted sqlite files using AES + CCM (URL...).And we're trying to use java's crypto package to encrypt the sqlite db file.The encryption is important because we don't want the client to be able to open the sqlite db file with any sqlite browser, only with our Air application.

View 1 RepliesJava :: Authorized Flash Client To Server Connection
Feb 22, 2011I'm building a Flash-based Facebook game with a Java backend, and I'm planning to use a RESTful approach to connect the two of them (not a persistent socket connection). I'm using the AS3 library to connect the client to Facebook, so that's where I have my session information stored. However, how do I authorize client connections back to the server? I can't leave the callback URLs open since that'd let people manipulate game state without playing the game. I need to make sure that the calls are coming from a valid client and through a valid session.
At the moment, users have no direct login to the backend server -- it's all handled through the client frontend. Can I pass the Facebook OAuth2 access token to the backend in a way that the backend can verify its validity? Should that be enough to trust a valid frontend connection?
I could do a two legged OAuth signed request or just use a simple shared secret, but the keys would have to be packed in with the flash client, which makes that almost useless for this use case.

Sep 24, 2011We have a typical Flash+J2EE application that makes multiple requests from client to server (over Flex remoting), which is taking quite a long time on some client systems (and hence results in poor application performance on such systems).
Now, suspecting issues with network connectivity (latency) on such client system(s), we need to identify how far does it contribute to the slow response of the application (rather than performance issues in the application itself).
So, what are the best way(s) to diagnose this on a client system (Windows)?
Note that we have tried profiling our application, which does not indicate bottlenecks there, so we just need to clearly identify the possible network issues.

Actionscript 3 :: Client + Grails Server - Processing Audio At The Client And Sending It Back To The Server
Mar 8, 2012We'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:

Java :: Indicate Failed Authentication Reason To Flex Client With JAAS?
Dec 29, 2009We're using :
JBoss 5
Flex SDK 3.5
BlazeDS 3, with integrated authentication (through JAAS and JBossSX)

However, the underlying JAAS LoginModule throws a specific javax.security.auth.login.LoginException subclass.
How can we propagate the failed login reason to the flex client ?
Java :: Externalizing Client ChannelSet Configuration For Flex Web Application?
Dec 10, 2010I am looking for an approach that will allow me to (somehow) dynamically pass the server name, server port, and web context to my Flex client so it can create a ChannelSet for it's RemoteObjects to use. These three properties are, of course, readily available to my Java server-side code so I just need a way to get them to the client.
By default, Adobe says you should compile your Flex application against the server configuration file "services-config.xml". This is a highly inflexible practice that Spring says should be avoided (I agree).
One popular approach is to use Flex's http service to download an XML configuration file. I like this idea, but I don't want to hard-code an XML file and keep it inside my WAR file. Is there a way to dynamically generate this from Java code?somehow use flashvars to pass the properties in from the containing HTML page to the SWF file. But again, I don't want to hard code them into the HTML page. Is there a way (maybe with Javascript?) to dynamically set the value of these when the page loads?

Flash :: Handle Client And Server Validation With Flex 3?
May 5, 2011I'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.
Java :: Push Data From BlazeDS Without Receive Message From Flex Client?
Dec 9, 2009I am using BlazeDS for data-push feature in my Flex application project. From the official tutorial, Getting started with BlazeDS, it shows messaging example with producer/consumer from API. but how can I implement server side which doesn't need to be invoke from Flex client, but from within server-side instead. I got some idea but I don't know how to do because I'm a Flex developer, not Java developer In Google, there's a tutorial show about I need to extend ServiceAdapter class in Java-side, which extends Invoke method. Do I need to extend other class instead of this to do what I want?
