Java :: Detect When Flex Client Closes The Connection?
May 13, 2010
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()) {

I have a Flex/Java/MySQL/Hibernate application running on tomcat/BlazeDS which have very LOW activity, the user can even not visit it for months.The problem that after a month of inactivity the connections between tomcat and mysql are closed and then I need to restart both the mysql and tomcat servers, is there a way to avoid that and maintain the connection always open?

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.

I'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.

Im trying to make connection from flex to java and from java to mysql. I managed to connect to java, but having error that class not found: com.mysql.jdbc.Driver. But i downloaded mysql.jar, included it added to library, and connection works when i testing it from clipse scrapbook. Dont know what to do, i spend last couple days on this.
Class.forName("com.mysql.jdbc.Driver");
String username = "username";
String password = "password";
[code]....
Basically the solution was simple. Everybody keeps saying to put jar into lib folder, so i done it, but i wasnt realised that i have to put into my servers lib directory, not app lib directory and this miserable mistake cost so much. Anyway i hope this will help for some newbie like me.In this particular situation im using red5, so i putted it into my red5 dist/lib directory and "surprisingly" its started to work.

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 been developing an application(a website to be more precise) which consists of a flex front end which is constantly sending and receiving data from the back end which is programmed in java. The connection between the two components is being done through blazeds. This worked fine while I was running it locally, however when I uploaded both sides of the application to a tomcat server(online) the following error is being returned when a connection between the components should occur:URL...I have read around about this error and many seem to getting this error when making connections between different servers, unlike here, where the connection is occurring within the same server.

I have a big issue with FMS 3.0 and specially with netconnections. Sometimes, when one client closes its netconnection, all the other clients of the FMS are also disconnected automatically. I am trying to find an explanation but nothing... It seems to be a bug as, most of the time everything works very well, but sometimes (not often) this strange behaviour happens. I don't know what to do and it's really annoying as it affects the reliability of my application.

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 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?

Is it possible to load a .properties file from a client computer using adobe flex? I have a flex app that needs to access a server and multiple URLs but the URLs may change frequently. So I think modifying and loading the URLs from a .properties file would be the easiest way update the URLs
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.
public function URLLoaderDataFormatExample(event:Event):void

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?

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.

Is there an easy way to detect when a (righ-click) contextmenu is visible? I wish there was a "visible" property for theContextmenu class, but there isn't one.I've tried to listen to events to know when the menu opens orcloses but it would seem as though there are far too many(undocumented) events to take into account and some of the eventsmay be OS specific.For example, the following 3 events cover much of thescenarios of when the menu opens/closes..cmMenu.addEventListener(ContextMenuEvent.MENU_SELECT,onShow);cmMenu.addEventListener(Event.DEACTIVATE, onHide);stage.addEventListener(MouseEvent.MOUSE_DOWN, onHide);But you can also click either the f10, alt, esc, or enterkeys to also close the menu. There could be other ways to close themenu, but since it is not well documented, I can't be certain.Too bad Event.CLOSE isn't dispatched when the menu closes.

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.
