Developing Flex Applications on Linux?

As a developer I would like to take advantage of flex to build media-rich applications. I haven't done much with Flash previously so I'm a little ignorant on what's available to me as an Ubuntu Linux user. I know that the Flash Builder applications only support Windows and Mac so I'm wondering if it is possible to develop applications without the use of Flash Builder? Trying to find answers on google didn't help so much because I often bot pointed back to the Adobe site or an article on just Flash Builder. I have already tried installing Flash Builder using Wine but I can never get past the initial install proceedure.
So is there any other compile software I could use? Also, If there is a way to compile the files using the command line I could do this as well.

This may help you.....

As far as I know, you can compile Flex 3 applications.

How can we develop flex application as 64 bit application?

I develop a 32 bit application through flex and i want to convert as a 64 bit application.
Is there any way to develop?

I may be wrong, but isn't the architecture ( x86 , 64bit ) the concern of the VM. That is one of the motivations for having a vm, you don't have to worry about the architecture your application runs on ( for the most part).

Develop flex applications with OOP concepts

Hi,
I have gone through the adobe learning path links, and i think i have a good understanding now of flex. However, i think it will be best if i do a couple of sample projects that are done using OOP best practices and also using best pracitices that adobe Flex preaches.
Can anyone recommend me some books that have sample projs that address both OOP and flex best approaches?
Thanks,

Need guidance in developing AIR Application based on flex 4.0.0.10396 sdk beta.

Hi Friends,
I need to develop a desktop mail client for web based RIA developed in extjs. The air application has to communicate with a flex application hidden inside the web app and get the SMTP Details and send mail using the socket connection.
Till date i have found few plugins and i am testing out each one of them.
1) byteArray SmtpMailer for socket mailing which has login authentication, attachment support.
2) suiggly with halo rich text editor for spell check enabled mail composer.
3) flash network localConnection for communication between web flex hidden inside extjs ria app and air app, The flex application and extjs application communicate using FABridge.js.
4) updateFramework for frequently updating the air app with new features.
Drawbacks i face:
1) ByteArray SmtpMailer works fine but i am unable to find a plugin for SSL encryption support which is required for connecting with gmail SMTP server.
2) The flex web application size grows upto 1.8MB(approx) with all SDK librarys which are part of 4.0.0.10396 SDK, which is thrice as big as the extjs RIA app.
3) The updateFramework for updating a air application throws errors, which is diffcult to troubleshoot or understand by novice like me.

Ok, just figured this out. The cert I created was somehow malformed. I simply created a new one with the Flash IDE which worked fine. Any other method of creating the cert that I tried failed, including the keytool command line utility.

Can Flex develop Windows Application ? Example or How to ?

Can Flex develop Windows Application ? Example or How to ?
Thx.

Take a look at AIR (formerly Apollo) in Adobe Labs.

Flex application running under AIR takes a long, long time to start.

I have a flex application which runs on a desktop under AIR. The application has an assets folder with 3,500 mp3 soundclips totalling about 50MB. The problem is, the application takes around 90 seconds to load. I'm sure that AIR is scanning the application folder and doing something with the contents because if I delete the assets folder it loads in about 5 seconds. Does anyone know why AIR/Flex would do this, and why it doesn't exhibit the same problem if I run or debug in Flexbuilder on eclipse? It's making my killer app unusable!
Thanks
Paulo

Well, I've spent a bit longer looking at this now, and the problem appears to lie with my encrypted local store. The first thing that happens is for the app to read the product key from the ELS. But, it fails (for some unknown reason). So, the app seems to hang there for 90 seconds until it eventually renders the welcome screen. If I remove the assets folder it still fails to read from the ELS, but only takes a couple of seconds to start the welcome screen. This is where the scanning of the application folder seems to come into play, because if I remove the code which reads from the ELS the app starts within 2 seconds whether the asset folder is there or not.
I think the slow startup and the scanning of the assets folder are just symptoms of a different problem, i.e. a problem with the ELS. I don't have the same problem with my development environment though - it's only when I test deploy the application.
Thanks for your help on this problem EgorKDie. I think I should be able to resolve it once I can sort out why the ELS is being awkward.

Flex Application does not work outside of the default dir

Hi,
I have developed a flex application which calls a http
service and displays the contents in a text area.
This works fine when I execute it from the flex builder or
from the directory where the flex builder stores it.
If I copy the files to any other dir or the server, after
making http call no result is displayed in the text area.
Is there any thing else i need to do other building
application in flex builder for deployment.
Please help,
Thanks in advance,
Chintan

How can I tell if a sound is playing in Flex application?

Hi All,
Simple question but I can't seem to find an answer to. How can I tell if my Flex application is currently playing sounds from a SWF file?
What I'm trying to do is load a SWF file dynamically into my Flex app. However, these SWF files have sounds in them and they don't seem to stop even after I unload the SWF files.
I'm trying to get around this by stopping all sounds using the flash.media.SoundMixer.stopAll() but it's getting called too early, before the SWF files are fully loaded and rendered in the application.
I searched around and it seems like many people are having issues with this. Maybe someone can help me find a solution.
Thanks,
Colin

In player 10 you can use unloadAndStop()

Error while loading a swf created in flash cs4, inside a flex application

Hi there,
I have created a rotating logo in flash cs4 using motion presets, named logoRotar.swf. I have used this inside my flex application:
<mx:SWFLoader width="33.33%" height="100%" source="assets/logoRotar.swf">
When I execute the flex application, I get this runtime error message:
VerifyError: Error #1014: Class flash.geom::Matrix3D could not be found.
    at global$init()
    at fl.motion::AnimatorFactory3D/getNewAnimator()
    at fl.motion::AnimatorFactoryBase/addTargetInfo()
    at logoRotar_fla::MainTimeline()
I also tried adding import flash.geom.*; statement in my flex application, I still get the same message.
Flash player 10,0,22,87 is running in my browser.
Please help me out....
Cheers!

Flash player in firefox is not giving the exact mouse coordinates while running a flex application in firefox. Actually it was working fine in the previous versions. I mean in the ver 5.5. In the latest version its not working fine

Hi Friends,
I face some mouse issues with the later versions of the Firefox (6 and above). When a flex application is executed in a Firefox, It runs on the flash player in the browser. While getting the mouse coordinates, flash player is returning some bad coordinates. Please respond to this as soon as possible

Getting error while running application on linux

Hello, I developed an application on windows and it works great on windows. Than I changed my OS to linux(ubuntu 64 bit) and I setup all the environment with following this article : http://docs.oracle.com/javafx/2.0/release_notes_linux/jfxpub-release_notes_linux.htm. On compile time there is not any error but when I run it I got this error.

Yes , it does. I might be wrong but, I think the problem comes from stage initalization. Because I check the logs and every thing is ok. My environment is:

Getting GTK error while running javaFX application on linux

I developed an JavaFX application that works fine on Windows. So, I tried to run this same application on Linux (ubuntu x86) and it is not working.

Spring Flex application on weblogic 10.3

I have developed an Spring-Flex application. I did the necessary changes to be done in web.xml, spring-config.xml and services-config.xml. The application is working fine on Tomcat server. But when tried deploying .war of the application on Weblogic 10.3, the navigation of the application is failing. Even the messagebroker defined on startup page if not receiving.
Is there any server specific changes need to be done on Weblogic before deploying the .war file?
Please provide the pointers.

Hi,
Did you configure your application module to use a JDBC data source? To do this, right-click the app module in the navigator, select Configurations and in the dialog that comes up change the connection type to JDBC Data Source and enter your data source name - which should be the same as the data source you created on the weblogic server.
Also, I do suggest you create an EAR file - this is what we've tested and certified with. You can find more details in the deployment chapter of the fusion developer's guide: http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/deployment_topics.htm#CHDJJDDG.
Hope this helps
