Existing Flex App With Air

I have been working on a large Flex App using CFM as the db
access layer. Essentially I understand that AIR will allow my RIA
which is currently solely used in a browser run off line as a
desktop app. However, my question is what's involved in modifying
this application to push 'new' data added while off line back to
the db when a connection becomes available.
Some guidance on this subject would be great, or is this
something which should require no modification?

AIR doesn't give you any synchronization mechanisms. It's
entirely up to you how you manage offline operation.
What AIR actually does is provide an out-of-browser runtime
environment for Flex apps, plus some additional APIs that Flex
couldn't give you due to its browser-based nature. Among them are
access to a local database, plus more generalized local filesystem
access. Between these two things, you can store local changes while
offline, then work out some way to push them to the server at a
later time.
You might make your first step into the AIR world just a
simple port of the existing application to run under the AIR
framework. This won't give you any new offline capability, but it
will let the app run as a desktop app, outside a browser. This may
make more sense for your type of application. Then once you get
that going, you can worry about synchronization.

Flex App with remoting works on local Apache server - fails on production server

Hi Everyone,
I have a Flex app that uses Data Services. The application works correctly on my local Mac Server and Apache. When uploaded to my production CentOS server, the Data Services fail. When the app is done loading, the following error message comes up:
Class "ModelsService" does not exist: Plugin by name 'ModelsService' was not found in the registry; used paths:
: /www/html/mdubb//PHP2/bin-debug/services/
#0 /var/www/html/mdubb/ZendFramework/library/Zend/Amf/Server.php(550): Zend_Amf_Server->_dispatch('getAllModels', Array, 'ModelsService')
#1 /var/www/html/mdubb/ZendFramework/library/Zend/Amf/Server.php(626): Zend_Amf_Server->_handle(Object(Zend_Amf_Request_Http))
#2 /var/www/html/mdubb/PHP2/bin-debug/gateway.php(73): Zend_Amf_Server->handle()
#3 {main}
Where getAllModels is a method of my custom ModelsService.
I changed the Zend path in the amf_config.ini file so it references the correct directory. If I browse to gateway.php, it prompts to download the file, which I think is correct.
I added in the config file the path to the services folder.
I tried adding $server->addClass("ModelServices") in gateway.php, but it didn't like that.
The file structure on the production server is the same as the local server (I litterally uploaded everything in my local web root), so I can't think of what would be differenet between the two.
I have already pulled one all nighter trying to get this to run. Do you know what I should troubleshoot next?
Thanks in advance,
Ryan

Configuring socket policy for flex apps(with blocked port 843)?

We have built several flex-based ecommerce apps for a fortune 500 customer of ours, that for various reasons, we need to use sockets to a different domain and requires a socket policy file, but were having trouble configuring our flex apps for deployment in thier enviornment where they are blocking virtually everything except port 80 . The current documentation in in regards to socket policy files and crossdomain files in a non-standard configuration not using port 843 is not providing any useful help to us.
Here is the scenario:
Flex apps are served from domain www.a.com in to users browsers via http. The apps then make socket connections to domain www.b.com:80 where there are php scripts serving json data to the flex apps via port 80 using http(we use sockets because we need to set and read back http headers). The problem is the flex apps cannot make socket connections to the www.b.com domain without errors like below(unless we setup a socket policy server on port 843 of www.b.com, in which case everything works):
Warning: Timeout on xmlsocket://www.b.com:80 (at 3 seconds) while waiting for socket policy file. This should not cause any problems, but see http://www.adobe.com/go/strict_policy_files for an explanation.
Error: Request for resource at xmlsocket://www.b.com:80 by requestor from http://www.a.com/bin-debug/DownloadManagerFlex.swf is denied due to lack of policy file permissions.
Error: Request for resource at xmlsocket://www.b.com:80 by requestor from http://www.a.com.us/bin-debug/DownloadManagerFlex.swf is denied due to lack of policy file permissions.
Since we cannot use port 843 for the socket policy file server, we setup the socket policy server on a different ip in the same domain: spf.b.com:80 (using the sample perl code Adobe provides), and per the docs(cited below), use Security.loadPolicyFile("xmlsocket://spf.b.com:80") before we invoke "socket.connect", to supposedly tell the flash player to check there for the socket policy file. The problem, as you can see from the error log, is that the loadPolicyFile("xmlsocket://spf.b.com:80") is ignored.
No matter what we do or how we set things up, we cannot get the flash player to recognize the loadPolicyFile(), it always wants to go to the port were making the socket connection on. It is unclear how to properly configure the flex app, socket policy file and crossdomain file for the above scenario. The docs allude to being able to serve the socket policy file from a different port 80 in the same domain as the socket connection were trying to make, but were having no luck with that.
->Can anyone shed some light on how to make this work or what are we missing/doing wrong? Also, if we can get this to work, are we stuck with a 3 second delay because this(very large) customer is blocking port 843?
As an aside, the documentation for all this is a bit scattered, unclear and contrdictory:
One document says:(http://www.adobe.com/devnet/flashplayer/articles/fplayer9_security_07.html)
"This warning usually means one of two things: first, that you need to set up a
            socket policy file server on port 843, which is the first location that Flash
            Player checks by default; or second, that you need to provide more explicit
            guidance to Flash Player from ActionScript by calling loadPolicyFile to indicate the location
            of a socket policy file. When you call loadPolicyFile rather than allowing Flash Player to check
            locations by default, Flash Player will wait as long as necessary for a
            response from a socket policy file server, rather than timing out after 3
            seconds."
Another document says(http://www.adobe.com/devnet/flashplayer/articles/socket_policy_files.html):
"If an ActionScript Security.loadPolicyFile() command exists within               the SWF file, then the Flash Player runtime checks that location. Flash Player checks               the destination of the loadPolicyFile() only after it has checked the               master policy file on port 843 for permission to acknowledge other policy               files. If the developer has not specified a loadPolicyFile() command,               then Flash Player checks the destination port of the connection."

I found the reason why the Flex application was ignoring the socket policy (crossdomain.XML). I have a policy server that listens to port 843 and submits the policy to the Flex client. My policy was getting ignored by the Flex application and I was getting the sandbox security error you were getting. The solution to this problem isto write a null byte right after the policy server sends the policy. I'm using Apache Mina that is wrtten is Java and the null byte is written as follows:
public void sessionCreated (IoSession session)
        throws Exception
        session.write(_policy); -- > policy string
        session.write("\u0000"); --> null byte
         //session.close(true); ---> No need to close the session because it is closed by the Flex client after it receives the null byte.
Now my Flex application can read and accept the policy from port 843 and I'm not getting more security violations.
Thanks for your reply,
Alberto

Error creating files. Compilation failed... when publishing iOS app with AIR 3.1 and Flash 11.5.1

Hello, I'm running Windows 7. I'm using Flash 11.5.1 (that's CS5.5 updated once) and AIR 3.1 to make an iPhone app.
I can export the app perfectly fine with either Ctrl+Enter or F12.
I added all the required things with AIR for iOS settings, such as a p12 certificate and icon files.
I then hit publish. After I hit publish, I got this error:
Error creating files.
Compilation failed...
I tried dragging the window to see if there was anything hidden behind the elipses. What can I do to fix this problem?

note sure if I'm much help other than to CONFIRM it is working for me by using the sdk WITHOUT the compiler. Check out adobe's little note: "Note : Flex users will need to download the original AIR SDK without the new compiler."
I am using FB 4.7 with AIR 3.6 and seems to compile correctly for iOS.
Maybe try reinstalling flash builder?
I honestly don't know if the JRE has anything to do with it... I'm using 1.7 ....to see what JRE you're using, open the Java Control Panel (I right click my java orange icon and hit properties), select the Java tab, then hit "View..."

Reuse a Flex App as AIR application

Hi!
I've developed a Flex application and now I want to use it
again with the same codebase as an AIR application.
But there are several factors that don't work as expected.
The Flex App uses some advanced features that make reuse a
little bit complicated:
I use the latest Cairngorm.swc in the app.
I use ResourceBundles in the app.
I often use "Application.application" in the app.
These are the three things, which make porting to AIR a
little bit complicated.
Are there any "Best practices" for sharing the same codebase
for Flex and AIR?
I've tried to make the Flex app a module and reuse that, but
then I get troubles with ResourceBundles, also the addressing
doesn't work correctly anymore (I've refactored the
Application.application.<element> calls to say:
Application.application.app.<element> where "app" is the ID
of the ModuleLoader). But I get the error that
<ApplicationType> cannot be converted to ModuleLoader.
Then I've tried to make a SWC out of the App, didn't work
either.
Has someone already done things like that?
What's the best way to accomplish that?
Thanks a lot for replies!
Bye,
Fritz

Hi.
Based on Adobe's document
http://www.adobe.com/devnet/air/flex/articles/flex_air_codebase.html
which I haven't found earlier, I got the project working with all
my special things lik Cairngorm and ResourceBundle.
Currently I'm writing a tutorial how this works, I'll post it
for further use on monday :-)
Bye,

I have created a Flex App with out a Server now I need one

So I'm new to Flex and didn't think the project needed a
server at first (poor planning on my part) now I'll need one. I
have alot built and would like to just conevert the app if I can.
The project has been sourced in to Subversion, I would like not to
have to rebuild the repository.
Thanks for the help

OK, so I think what you're saying is that you have developed
locally, which is good, and are using java objects as your back end
solution - I'll just state that Java is the *only* method of data
transfer that I haven't used (I use ColdFusion, XML, WEb Services
mostly), so at some stage I may not be able to help you.
Still, lets see how far we get. So, you can deploy your SWF
file to any web server, and browse to it with your browser. The
output in the /bin directory will include the SWF (usually the name
of the project) and a html wrapper file.
Is the Flex app actually rendering (i.e., your containers)
before you get the error? (I'm trying to determine if the problem
is the data transfer or the flex app proper)??

Generate PDF from existing flex app

Hi all,
Is there a way that i can generate a pdf file based on the
existing flex application? For example, if i have a VBox called
"my_vbox" and it contains some child elements, so how can i simply
create a pdf that contains all my_vbox's content?
Currently i only have a dummy solution that to print the
template and use Acrobat Professional to convert it, e.g.
var printJob:FlexPrintJob = new FlexPrintJob();
if (printJob.start() != true) return;
printJob.addObject(my_vbox, FlexPrintJobScaleType.SHOW_ALL);
printJob.send();
So is there a solution that as easy as this one to "print" my
whole template into a pdf? I have tried AlivePDF but it doesn't
support pdf creation from IUI component(s).
Thanks in advance!

Hi,
Have you tried the addImage() method of AlivePDF? It takes a
DisplayObject as input:
public function addImage(pDisplayObject:DisplayObject,
pAlpha:Number = 1, pBlend:String = "Normal", pMatrix:Matrix = null,
pResizePage:Boolean = false, pEncoding:String = "JPG",
pQuality:Number = 100, pX:Number = 0, pY:Number = 0, pWidth:Number
= 0, pHeight:Number = 0, pLink:String = ""):void

Audio is not playing first time in Flex app with 11.2 Flash player.

Hi,
I am playing an audio fle as flv in a flex application with flash player 11.2 but it is not playing first time and it is playing afetr pause/play and page refresh. Loacally it is playing fine. Please help and guide me.
thanks in Advance
Rangrajan.

Taha,
Not sure that I understand your workflow there. For editing, the 48KHz 16-bit is the "standard." The 32KHz is not.
Now, what is the Sample-Rate of your original material?
What is the CODEC used in that muxed (multiplexed, i.e. combined Audio & Video) file?
Did you allow Conforming complete 100%? This ARTICLE will give you some background.
Do you see the Waveform Display for that Clip? Alt+click on the Audio portion of the Clip, and then Dbl-click on it to get it into the Source Monitor. Do you see the Waveform Display there?
Have you added any Keyframes, or Effects to that Audio? Toggle the Keyframe Display in the Track Header, to see if there are any Clip, or Track Keyframes there.
Have you accidentally Muted that Track? Look at the Visibility (eyeball) icon in the Track Header. Then, look in Audio Mixer to see if that Track is Muted.
Good luck,
Hunt

Converting Flex app into Air?

i wonder is there a way to convert a Flex 3 application into an Air app for desktop distribution?
thanks
krs

You can easily do this by changing the <mx:WindowedApplication> tag of the main app file to <mx:Application>.
Any other code that is AIR only, such as accessing the local hard driver with FileSystemTree, etc. must be removed, disabled, or modified as appropriate.
If this post answers your question or helps, please mark it as such.

Deploying Existing Web App With New JWS

Hi all,
I've been banging my head against a brick wall for a few days on this, but I'm sure it must be something trivial. Hopefully someone here will have some advice...
In a nutshell, I'm working on an existing web application, running on Weblogic 8.1, in a clustered environment. I've added a new JWS web service which is largely standalone, but it uses controls from elsewhere in the application.
Locally, on my development box, it works perfectly - I can run it from Weblogic Workshop, and see the handy test form to run the web service, as well as seeing the WSDL by pointing my browser at http://localhost:7001/app/path/Service.jws?WSDL
However, I've now built the EAR for the whole application, and deployed it to our test environment (clustered - a mirror (hopefully!) of the production environment).
When I go to http://test-box:7002/app/path/Service.jws?WSDL I see a nasty-looking error page that looks like:
WebService ERROR
Error:
null
Stack Trace:
null
When I try the same URL without the ?WSDL on the end (so just http://test-box:7002/app/path/Service.jws), I see the nice Weblogic Web Service page, showing that it knows there's something there, but it has no content, just the 'Overview' tab, followed by:
Public Information
about Service.jws Web Service
and that's it - locally I see the same thing, but with options for viewing the WSDL and testing the service.
I'm confident that the URL is correct, because if I put rubbish in, I get a different error message.
Reading around, I've found lots of resources for 'how to deploy a web service to a production environment' for Weblogic 7, but much less for 8.1. I've seen references to jwsCompile, for example, which I think is specific to 7, because I can't find any references to it in the 8.1 docs, but perhaps that's wrong?
I'm pretty sure there's a configuration setting I'm missing, or a step in the deployment, but I'm stuck as to what it is!
Any advice gratefully received.
Edit: I should have mentioned that there are two other JWS's in the same app, both of which have the same symptoms as my new one (they've been there for a while, but are unused).

My gut reaction is that there might be an issue with the frontend settings not set up correctly, see 9.2 docs in lieu of 8.1 docs:
http://edocs.bea.com/wls/docs92/webserv/setenv.html#wp220521
You should also open a support case as they could probably identify your issue quickly.

Viewing online images in native phone apps with AIR?

Gidday guys
What's the standard way of loading an online image into a native phone app? An image that can't be packaged with the app as it may have been changed by the user eg a profile picture, or their logo?
Cheers

Yes - I do this with my desktop AIR app.
What I'm wondering though is it OK to do this for phone apps, or is there some advantage to emedding the images and putting them in your project's assets folder? eg phones being able to cache images from assets, but not if the images are built into the swf.

Package command line app with AIR app

Forgive me if I seem completely dense, but I've been googling and forum finding and hair pulling all day on this.
I wrote a command line application and I call it from my air application. It all works just fine, but right now the location of the command line application is hard coded. I want to know:
1) What is the actionscript that allows me to refer my nativeProcess call to a an application that is packaged with the air app when I export?
2) Where do I place the command line application in the file system of flash builder to bundle it with everything when I export?
I realize it'll be different for mac and windows, but I need to do both. I'm starting with the mac. Right now as far as I know I can put the command line app in the source folder and that all ends up in the .app/contents/resources folder, but I'm not exactly sure how to reference that in actionscript or if I can or if I should? I don't know. Clue me in?

Can you not use File.applicationDirectory.url as a base?
