Java :: Externalizing Client ChannelSet Configuration For Flex Web Application?
Dec 10, 2010
I 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?

We are using an XML file as an external configuration file for several parameters in our application (including default values for UI components and properties values of some service layer objects). The idea is to be able to load the XML configuration file before the flex application initializes any of its components. This is crucial because XML loading is processed a-synchronously in flex, which can potentially cause race-conditions in the application.
For example: the configuration file holds the endpoint URL of a web service used to obtain data from the server. The URL resides in the XML because we want to allow our users to alter the endpoint URL according to their environment. Now because the endpoint URL is retrieved only after the XML has been completely loaded, some of the application's components might be invoking operations on this web service before it is initialized with the correctendpoint.The trivial solution would have been to suspend the initialization of the application until the complete event is dispatched by the loader. But it appears that this solution is far from being trivial. I haven't found a single solution that allows me to load the XML before any other object in the application.

We 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.

Since I'm developing a multiplayer card game for Facebook using Flex as client side and Java SE as server side, I wanted to know how do I actually make the connection between Flex and Java? the server and client should be able to send each other data(cards,movement,room information etc...) across and I wonder what's the easiest way to do it without complicating it. where to read about it ? I know JAVA but I find JavaEE hard to understand.

I have a Flex application that connects to a BlazeDS server using the StreamingAMF channel. On the server-side the logic is handled by a custom adapter that extends ActionScriptAdapter and implements FlexSessionListener and FlexClientListener interfaces.
I am asking how can I detect which "flex-client" has closed a connection when for example the user is closing the browser? (so I can clean some infos inside the database)
I tried using the following:
1. To manually manage the command messages:
@Override
public Object manage(final CommandMessage commandMessage) {
switch (commandMessage.getOperation()) {

We're using :
JBoss 5
Flex SDK 3.5
BlazeDS 3, with integrated authentication (through JAAS and JBossSX)
Failed login are always indicated to the flex client by the same fault code : Client.Authentication
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 ?

I 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?

I was able to use florians suggestion and I've added the code below if anyone else is interested. I used the example here URLLoader.

I 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?

My 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.

We 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.

I hope i'm in the correct forum to ask this. I am trying to find the application-level configuration folder for my Flash CS4 program.
I assumed it would be in C:Program FilesAdobeAdobe Flash CS4enConfigurationComponents
But it is not. Should I have such a folder? And, if so, where should it be?
Or do I need to create it myself?

If you subcribe a Consumer in Flex, you need to assign a ChannelSet to the Consumer. In my case, I create a ChannelSet and then add a Channel to that ChannelSet.Apparently, the added channel is the current channel of the ChannelSet. But what if I would add two Channels to the ChannelSet? Do I need to set the currentChannel before subcribing?If there are two channels in the ChannelCet, and I trigger the login method on the ChannelSet, will both Channels be authenticated and connected?

It has just occurred to me that when my Flex application does a ChannelSet.login, it is essentially sending the username and password over the wire in an unencrypted form to the BlazeDS server. While I use the binary AMF protocol over an AMFChannel, it would take nothing for somebody to sniff these passwords.
Most of my clients do not want to run their application on an https (SSL) protected site. So what is the best way to do this? I use Spring security on the backend to do authentication.
Should I encrypt the credentials myself before calling login? I guess then I would need to know the server-side encryption algorthym.

i recently had a look to the tutorial for custom authentication within a flex application. The login is managed by getting the ChannelSet from a RemoteObject:
private function creationCompleteHandler():void {
if (cs == null)
cs = ServerConfig.getChannelSet(remoteObject.destination);
[Code]....
After that the channlset can be used with the login command of ChannelSet. How can i insure that this is using a secure connection? I know that there is a amf channel and a secure amf channel. But how to tell to provide the credentials in a secure connection?

Can Flex be used for a desktop application whose business logic is written using Java? Everything I've read about flex uses a remoting or http protocol to communicate with the backend via a J2EE server, so I'm not sure how that would work for a desktop app (unless an embedded j2ee server was running in the app).

I'm just learning about Flex and I'm loving it. Unfortunatly I still have to make the decision on which RIA technology to use and its dependent on, among other things, from the following case: How can we wrap a java applet around a Flex application? More specifically, I would like to wrap/integrate NASA's World Wind applet in a Flex panel, similar to what Adrew Trice did with the Google Earth API.
An alternative would be id Flex would support direct access to the 3D hardware through OpenGL or DirectX. But I do not think that that is the case yet, not even through AIR.

What's out there that lets you do this? Are there any OSS projects or maybe something a little more popular than this:[URL]? This does exactly what I'm suggesting (i.e. cuts out the need for Swing UI for the most part) but for a number of reasons I'd be interested in any better alternatives. alternatives would need to support the Flex SDK.

In my Flex application, channelSet is reset on each browser refresh.If you've authenticated and refresh the page and check channelSet. authenticated, it says false, but your remoteObject calls will still work because the server session still exists.I have a service call that checks for a session on the server and can identify that one exists when a user has already authenticated and not logged out, but how can I bypass login and still set the channelSet.authenticated to true without calling channelSet.login() when they come back to the page(before a timeout occurs, of course)?The user session isn't closed if you exit the browser. Currently it does in fact make you log in again. But there is an existing session so blazeds returns a re-authentication error if you're not the user in the session, and it also allows you to login with any password if you are the user because it sees that the session has already been authenticated.So how can I make it so the session is invalidated upon closing the browser or refreshing? I could do it by automatically logging out when the app starts, but that doesn't seem very elegant.[code]
