Flex and Seam

Do you think it may be possible to integrate Flex Data
Services with JBoss's Seam framework?
Thanks,
Pepe.

Yes.

JSF is a component based framework not an MVC framework a la
Struts.

In fact, Seam's livecycle is much near to Flex's that what at
first sight may seem.
Seam Remote, which is an AJAX remoting framework, allows to
call EJBs methods
directly from Javascript => no page refreshes.
What I was asking with this open question is if someone has
tried to develop an
EJB3Adapter or SeamAdapter that synchronizes the FDS
framework with the workflow part of Seam.
OTOH a JSF render kit for Flex, if something like that is
possible, would be a cool path to explore.

Pepe.

Problem in creating client side PDF with image using flex and AlivePD

I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance
Atishay

I am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing?

How do I save a file to a server using flex and coldfusion?

How do I save a file to a server using flex and coldfusion?
On the CF side I might need to use this:
<cffile action="UPLOAD" filefield="Filedata"
destination="#expandpath('..\somepath)#"
nameconflict="overwrite">
And on the flex side I might need to use something like this:
var sendVars:URLVariables = new URLVariables();
sendVars.action = "upload";
var request:URLRequest = new URLRequest();
request.data = sendVars;
request.url = _strUploadScript;
request.method = URLRequestMethod.POST;
_refUploadFile = new FileReference();
_refUploadFile = _arrUploadFiles[_numCurrentUpload].data;
_refUploadFile.addEventListener(ProgressEvent.PROGRESS,
onUploadProgress);
_refUploadFile.addEventListener(Event.COMPLETE,
onUploadComplete);
_refUploadFile.addEventListener(IOErrorEvent.IO_ERROR,
onUploadIoError);
_refUploadFile.addEventListener(SecurityErrorEvent.SECURITY_ERROR,
onUploadSecurityError);
_refUploadFile.upload(request, "file", false);
I just don't know how to put it all together in Coldfusion.

Flex and Java on Desktop

Hi
We are having this requirement , we want to develop a
application using flex for adobe AIR runtime which will communicate
with java in the desktop, we are not having any servers here, so
flex application want to communicate with java classes with out the
help of any server so I can't use httpservice, webservice or
remoting .
I like to know the ways to communicate from flex 3.0(Adobe
AIR) to java files (java takes care of splitting PowerPoint
files and converting it into serious of jpeg files, and
creating ppt files from the objects returned from flex ).
Is there any other way to communicate form between flex and
java in the desktop ??? please give inputs
Thiru

Hi,
you could use XMLSocket or Socket classes depending on the
type of communication you want to stablish.
I have been testing this for a while although not for a
project.
However my impression is that you need to install the AIR app
which is self-extracted and installed, but in second hand, you have
to install the Java app, that acts as a server, and it must be
executed every time your AIR app is, and the other way around.
Untill now I haven't got any idea on doing this without too
much work, but you can take a look at the Merapi project.

Sharing code between Flex and AIR versions using library project

Hello everyone,
I'm developing an application that has both Flex and AIR versions. In order to share code between these apps, I created a library project and added all my code there. Now I've set the library project as a dependency for both Flex and AIR projects. Since there are some components that use the DataService object, I've added fds.swc and fds_rb.swc and fiber_rb.swc modules to the libs directory of the library project. No compile errors. Now, if I try to run my Flex application, I'm getting this error:
Variable mx.data::LocalStoreFactory is not defined.
I know that this error comes up when playerfds.swc is not present in the path. But that is not the case here. I have added playerfds.swc, fds.swc and related lib files to the build path.
If I go back and add the playerfds.swc file to the original library project, the error no longer appears. This is not a proper solution for me, since I need to share this project with AIR version also, and I cannot have both playerfds.swc and airfds.swc in the same project.. Has anyone faced an issue like this before?? What am I doing wrong??

Thanks, Flex harUI, for the direction in regards to isolating build changes. That aside (still working on it), can you offer any direction in regards to my original question on SDK and AIR compatibility? I'm specifically looking for a version compatibility mapping or anything that definitively states, "Flex SDK x.y.z works with the following versions of AIR". This information is crucial for us in order to more specifically plan our own roadmap built upon these two frameworks as we consider both existing installations of our software and future distributions.

Flex and BlazeDS Compile for Deployement

Hi,
I've been following the Flex + BlazeDS tutorial on the Message Service from adobe to start learning working with blazeds. Everything worked out great on the local server of course but I got stuck when it came to moving the files to a remote server. I've looked around quite a lot and found out it's because the compiler feeds the services-config.xml upon compile and at lease in my case won't take and external file. The solution everyone has been posting on the net is writing the channels in actionscript within flex and feedin it the valid endpoint that would be found in the xml configuration file. That's all nice and dandy but everyone has been talking and showing examples of this being done for RemoteObject and I haven't managed to find any examples for Messaging.
Can anyone help me out with an example on how to deploy my application to a server? (either by coding the channels in AS or otherwise) The application itself is pretty basic...
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
      xmlns:s="library://ns.adobe.com/flex/spark"
      xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="200" minHeight="480" creationComplete="consumer.subscribe()" width="250" currentState="EnterName">
<fx:Script>

   import spark.events.TextOperationEvent;
]]>

<s:State name="EnterName"/>
</s:states>
<fx:Declarations>
<s:Producer id="producer" destination="chat"/>
<s:Consumer id="consumer" destination="chat" message="messageHandler(event.message)"/>

    var message:IMessage = new AsyncMessage();
    message.body.chatMessage = user.text + ":" + " " + msg.text;
    producer.send(message);
    msg.text = "";
   private function messageHandler(message:IMessage):void{
    log.text += message.body.chatMessage + "\n";
]]>
</fx:Script>
<s:Panel title="Chat" width="100%" height="100%">
<s:TextArea id="log" height="377" x="10" y="10" width="228" includeIn="Chat"/>
<mx:ControlBar width="246" height="52" x="1" y="395" includeIn="Chat">

   </mx:ControlBar>
<s:TextInput includeIn="EnterName" x="60" y="177" id="user" />
<s:Button includeIn="EnterName" x="87" y="207" label="Start Chat" id="chat" click="chat_clickHandler(event)"/>
<s:Label includeIn="EnterName" x="57" y="157" text="Please Enter Your Name"/>
</s:Panel>
</s:Applicatio>
And besides that in the messaging-config.xml file on the server a destination with the id="chat" is created and that's it.
Any help or pointing in the right direction will be greatly appreciated.
Thank you,
Nick

Update:
Ok...I finally figured out that by replacing the tokens in the services-config.xml file with the physical address of the server everything works.
Anyway...this means the application needs to be compiled everytime it is moved to a new server or even a different folder on the same server for that matter. Is there any way to pass the {server.name}, {server.port} and {context.root} tokens to the application at runtime for messaging?
Thanks,

Getting Started with Flex and Java RPC for Free?

Good Morning,
Please forgive me if this is the wrong place to post- I'm
just having trouble wrapping my head around what is and what isn't
available for free in the Adobe Flex world.
I've been working on an application for the last few months
using Open Laszlo (
http://www.openlaszlo.org/),
but I've been running into frustrations with their lack of
up-to-date documentation, and I've found it difficult to bring new
people into the project, since the set of users who know it is so
small.
While I do like that I can compile to DHTML, that's not
enough to hold me there.
I've been looking into Adobe Flex, and it seems like a good
alternative- I'm comfortable paying $500 for the IDE-
I use Eclipse currently, so having a plugin for it sounds
ideal. That said, when I look into ways to talk to a Java backend,
everything points to Flex Data services, which is now part of some
larger package costing tens of thousands of dollars.
I don't need advanced messages, or data synchronization, as
nice as it would be.. All I really need is the ability to call a
Java method, and get an object back, which I can then work with in
Flex.
I see the forum message that asks
"How
do I 'do' Flash for free?, but this only talks about RPC very
broadly. Given that the message is from over a year ago, I thought
it would be better form to start a new topic, than replying to it.
Can someone explain to me what components I'd need, both on
the client side and the server side?
Is there a set of manuals that explain how to do Flex RPC
from Java?
Can Flex compile to any versions of flash earlier than 9?
(Flash 6/7 is still in wide deployment)
Do I want to start using Flex 2, or Flex 3? Are the
components compatible? Will the F3 docs be ready?
Finally, where can I purchase the Charting components? The
ability to create charts such as
this
overcome a decent price barrier.
Thank you for any insight you can offer, and direction you
can provide.

Dynamic value objects in flex and coldfusion 9

I'm writing a program for a company that does registrations for conventions and trade-shows. The problem I'm having is that each different client wants to store different data for each show. Most of the data is the same (attendee's name, address, etc...), but each show has some customizations that it wants to have... So each database for each show is going to be different...
Right now, the only way I know how to transfer data from Flex to ColdFusion is via a Value Object. (Well, the only good way to do it, that is.) My problem comes when a client wants a particular database customized. I have MANY questions about this...
1) How do I tell my Value Object what fields we've added to or changed in the database without re-writing the entire VO (in both the .AS and .CFC files) and re-compiling my program? In other words, I need a dynamic VO that changes automatcially with the database.
2) If there is a way to dynamically create a VO in Flex (and from a few blog posts I've seen, it seems there is a way), how do I tell CF9 what the structure of that dynamically-created VO is? Without re-writing a bunch of .CFC files every time I add or change a field in the database, that is...
3) How do I reference the dynamically-created fields in my Flex program? Right now, for example, I can define a variable called attendeeInfo as type attendeeInfoVO, and then reference things like attendeeInfo.first_name, attendeeInfo.last_name, etc... How do I reference a field programmatcially when I don't know what it's going to be called beforehand?
4) How do I make my program display/modify those dynamically-created fields? Right now, using the attendeeInfo example above, I can create a TextInput with an id="firstNameInput" and just say firstNameInput.text = "{attendeeInfo.first_name}". That won't work when I have no clue how many dynamically-created fields there are, or even what kind of data they're going to store... How do I deal with this?
5) Is there something other than VOs that would fit this situation better? Am I limiting myself by using VOs in the first place? Is it just plain impossible to do this with VOs? And if so, what are my alternatives? I need a structured object that can be passed around with a single reference -- I absolutely DO NOT want to pass a bunch of references to a bunch of different variables -- that's why I used VOs from the very beginning.
6) Can I simply PAY someone at Adobe for one-on-one help here? Do they have experts that you can "buy" for a few hours? What's the charge for that, if such a thing is available? Or, is this problem well-explained somewhere on the Web, and I just haven't found it yet?
I'm very confused here, and it seems like I might have to re-write a ton of code, which I'm not looking forward to... Ugh... I appreciate any help you can give me...
Thanks,
Laurence MacNeill
Mableton, Georgia, USA

This blog post is pretty close to what I want:
http://justinjmoses.wordpress.com/2008/10/10/flex-dynamic-bindable-value-objects/
So there are the dynamic value objects I was looking for. But the blog-poster is using LINQ and .Net 3.5. I'm using ColdFusion9.
So, how do I get ColdFusion9 to deal with that? How do you get CF9 to recognize the fact that you've changed the VO, and deal with it appropriately?
Thanks,
L.

Flex and HTML display shift in Safari in Mac OS

When a popup is displayed in Flex app, the Flex display gets shifted down in Safari in Mac OS alone. However, even if the display is shifted down, the controls seem to be in the correct position. For example, for clicking a button, the cursor has to be some pixels above the shown display. Not only the Flex display shifts down. HTML Links display also shifts down along with Flex and Links are clickable some pixels above the display.
The problem happens only while triggering the Flex popup display in long flex screen. On a Flex screen within the browser height, with the same actionscript and Javacsript code, there is no problem.
This works fine in all other browsers including Safari in windows.
Has anyone faced this scenario? Any help will be highly appreciated.
For the popup to be displayed in center of viewable area, the following code is used.
callLater(SMBObjectUtil.changePosition,args);
In SMBObjectUtil.as file,
public static function changePosition(x:int, y:int, obj:UIComponent):void {
     var yPos:int = ExternalInterface.call("findScrollTop");      var winHeight:int = ExternalInterface.call("getWindowHeight");
     var appHeight:int = Application.application.height;
     var objectWidth:int = obj.width;
     var objectHeight:int = obj.height;
     var calculatedX:int = 0;
     var calculatedY:int = 0;
     if(Application.application.width>obj.width) {
          try {               calculatedX = (Application.application.width - obj.width)/2;
               if(yPos <= 0){                    calculatedY = ((winHeight-objectHeight)/2-100)>0?(winHeight-objectHeight)/2-100:50;
else if(yPos<=(appHeight-winHeight)){                    calculatedY = (((winHeight-objectHeight)/2)+yPos-100)>0?((winHeight-objectHeight)/2)+yPos-100:50;
else if(yPos>(appHeight-winHeight)){                    calculatedY = appHeight - objectHeight - (winHeight-objectHeight)/2;
          catch(e:Error){          }
     }else {
obj.x = calculatedX;
obj.y = calculatedY;
Javascript functions used are:
function findScrollTop()
var ScrollTop = document.body.scrollTop;
if (ScrollTop == 0)
   if (window.pageYOffset)
    ScrollTop = window.pageYOffset;
   else
    ScrollTop = (document.body.parentElement) ? document.body.parentElement.scrollTop : 0;
return ScrollTop;
function getWindowHeight()
var y = 0;
if (self.innerHeight) {
   y = self.innerHeight;
} else if (document.documentElement && document.documentElement.clientHeight) {
   y = document.documentElement.clientHeight;
} else if (document.body) {
   y = document.body.clientHeight;
return y;

Found a fix for this. CallLater() was giving the problem in Safari. Once I removed CallLater and directly called my function, the problem was resolved.

Which is better as UI technology among Flex and Oracle ADF for oracle SOA suit

We have one application which is using oracle’s Service oriented Architecture (SoA) suite. Currently, there is a debate on the technology for UI in the new architecture that will be rich, easy to maintain, scalable and integrates well with SOA suite. We have two options one is Flex and other is Oracle ADF. UI part contains number of graphs, tabular and charts data. So it would be great if any one suggest which technolgy will be better for UI point of view. Thanks in advance.

Hi,
I looked at the demo
http://download.oracle.com/otn_hosted_doc/jdeveloper/11gdemos/ADF112/ADF112.html
It's interesting.
However, I would point out two things:
1- Before Oracle, Sun failed with UI technologies: there was AWT then Swing then Java FX. None of them was a star. The only place where Sun really won the UI war is the Bluray Disc format.
2- About half of the RIA in the financial/banking industry are developed with Flex, the other half is developed with Silverlight / WPF. HTML 5 is being taken up by some, but you still end up with the usual problem of having to pick up an AJAX framework, and get tied to a vendor anyway in the end. Never heard about any project developed with Oracle ADF yet.

Flex and Coldfusion error handling

Hello! I was wondering if someone could point me in the right direction regarding error handling in a Flex app thats using an HTTPSERVICE RPC to a Coldfusion component.
If a user is entering form data in Flex and clicks submit... the data is sent via the HTTPSERVICE send method as XML to the CFC. But what if there is a Coldfusion SQL insert statement error? Say a user enters a character in a number field (now i know the best thing to do would be to have actionscript ensure that the values entered are numbers but lets keep that aside just for this example). How could I alert the user to let them know the CFC encountered a SQL error? Or better yet... alert them that everything went "A" ok and their data was successfully submitted.
I originally thought to put CFTRY and CFCATCH around the CFC code. I could do that fine, but had trouble passing back a message string so that FLEX could use it in an Alert.Show window.
Thanks!
-BosDog

Hey Mike,
Sorry after I posted I thought "this may be a question for CF guys as well".
I definitely use and love RemoteObjects. Its great for binding to datagrids and to run SQL to return data from the server back to Flex. I've struggled with successfully passing variables from Flex to CF using RemoteObject though. Say a dataform with 5 text fields & 2 combo box dropdowns.
I think you may have forgotten to post the link to the article for me to read... i didnt see it in your last post?
Thanks!

Flash, Flex, and the iPad

While there is no shortage of iPad/Flash discussions on the Adobe and Apple forums, after searching for a couple hours now I have been unable to find the answers to my specific question. So please forgive me if I missed it somewhere.
As I understand it, Apple does not support Flash for the mobile and iPad devices. This is reiterated in a number of Apple forum postings that I just read, as well as Steve Jobs' rant here:
http://www.apple.com/hotnews/thoughts-on-flash/
However, I came across this Adobe press release from less than a year ago:
http://blogs.adobe.com/ukchannelnews/2011/06/20/announcement-mobile-applications-for-andro id-blackberry-iphone-and-ipad/
Apparently this Flex thing allows me to develop cross-platform mobile applications. So I do some research on Flex, trying to figure out the difference between Flex and Flash. I come across Adobe's FAQ here:
http://www.adobe.com/products/flex/faq.html#flex-flash
It's not real clear to me, but it sounds like what they are saying is that Flex is simply a programmatic framework around which I can build Flash applications, especially helpful for those more familiar with traditional programming. If this is the case, based on Adobe's press release above, it sounds like I should be able to use Flash on the iPad via Flex? What am I missing? Is there other differences between Flex and Flash? Or perhaps is it the difference between an application and browser support (like Apple's Safari)?
Thanks in advance for your patience, and your help.

It's easy Pea...
Flash is a plugin. It runs from withing the browser IE, Firefox, Safari, Opera, etc... It also can be run standalone, via special exe program on Windows platform.
Although this is less common. Here are all the Flash versions: http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html
AIR is a cross platform runtime, kind of like Java (build once run everywhere). But with AIR it's a bit more tricky. You have to compile your program to each target platform (Desktop, Andriod, BlackBerry, iOS) separately. It's not like with Java where you can indeed run your jar file on lot of platforms. AIR is essentially Flash "on steroids" as it mostly has the same API as Flash and builds on top of it. But AIR not in the pluging form, i.e. you don't need a web browser to run it from.
Here are the latest AIR runtime: http://get.adobe.com/air/
and SDK: http://www.adobe.com/devnet/air/air-sdk-download.html
You will need AIR SDK to build AIR applications and it has to be overlayed on top of Flex SDK which you can find here:
Flex SDK: http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4.6
Now Flex SDK is essentially a component framework. You will need a button in your application, or a Video component, right? So that is what Flex provides for you free of charge.
Obviously this sound simple but Flex is much more then that and here is your
Flex documentation: http://www.adobe.com/devnet/flex/documentation.html
So, Flex is a component framework which lets you build applications which target either Flash or AIR as executable runtime. For Flash it is called Web application and it runs from withing browser or standalone Flash player. For AIR it is called Desktop or Mobile project and it runs from withing AIR runtime which has to be installed on your device or bundled with your application.
Now, speaking of Steve rants, yes, they wanted to kill Flash on their platform, there was even a guy there who was responsible for that result (I forgot his name but you can google), although Adobe never admited that and played it nice with Apple. Why they wanted to kill most expressive and complete vector and video engine on the web (Flash)? It's simple! This is beacase they wanted to play on their nice and cozy iOS/iPad/iPod playground alone! Because they want to control the delivery of the content from publisher to consumer. they want to stick their proprietory products and specifications in between and skim the money! That is why they don't need Flash in the browser. Flash allows people to publish and consume an impressive content without charging a dime! That includes H264 video among other things. And that is what Apple doesn't want to see.
Good luck with Flex and everything else,
SdS
