Flex Hosting

Hello all,
I'm trying to write a desktop application that, finally, will
embed a flex 2.0 application (yes, imagine a kind of SAFlashPlayer
that is "ExternalInterface" aware.)
It is a mandatory request that this desktop appl is cross
platform so I am writing it using C++ (I cannot do it using C#)
It is also mandatory that both applications (desktop one and
flex one) can call each other.
Given that situation, I am using the NPRuntime approach to
build the flexhost layer in such a way that the flash player feels
like if it is being hosted by a internet browser like FireFox or
safari. The results are very exciting, except for the
interoperatibility between the host and the flash player plug-in:
When I use ExternalInterface to issue a call from the flex
appl, my host appl receives a string containing javascript code. I
think that flash send that flavor with the hope that it is going to
be evaluated by its host (because it thinks that the host is a
javascript enabled browser.)
At this point, it is frustrating for me because I
(erroneously) supposed that the host appl will receive an xml
describing the function call (that's the exact way that the activex
version of Flash player does when it is hosted by any other
windows application different from MSIE)
So, the question is: Is there anybody out there that know if
it is possible to "tell" Flash player to issue
ExternalInterface.call in, let's say, XML flavor instead of
javascripts evals?
Thanks in advance.

If you are selecting a web site hosting company, consider,
will you need one that supports ColdFusion, PHP, CGI, do they offer
a database, how about hosting J2EE apps? Hard to think of what you
might need in the future, but better to think of it now.

What to look for in a web hosting company for Flex applications

Hello,
I am trying to figure out what I need to look for in a web
hosting company if I want to deploy my own Flex applications? I
don't anticipate having any special requirements other than the
ability to interact with databases and XML files. Can someone help
me figure out what the server-side requirements are?
Thanks in advance!
Matt

then almost 99.9% hosting will work.
if you want a Flexx app with compiler then oo thats different
but as you say "I don't anticipate having any special requirements
other than the ability to interact with databases and XML files"
then you can go with pretty much any hosting, as long as they have
apache, Database serve and I think thats it.

Read .xls from specific path in host server in flex 4.5 using As3xls?

Hi Guys
I am New to flex programming and I have some doubts regarding exporting data from excel file to flex
1) Is there a way of reading excel file from a specific path in host server in flex 4.5 using as3xls?
i.e is I want to read a flex file from a specific path in the computer.
2)Is there a way of reading excel file from a specific location in a website?
I have been trying find a solution to this for a long time but have hit a dead end. any kind of solution will be really helpful. Thanks in advance.

Someone suggested it could be a serialisation issue but I I'm not sure how to go about checking that.
Any suggestions ?

Question about hosting - Flex/Coldfusion

I'm wanting to use Flex to display Coldfusion info.
just went through the tutorial at http://www.adobe.com/devnet/flex/articles/fcf_getting_started_coldfusion_flex_02.html and I got the example to work on my local machine. I was also able to do the same with my own data. But the example uses remoting services and I don't know what my hosting providers have on their servers.
I'm using CrystalTech.com, which is an Adobe partner. But they said they didn't offer Flash remoting on their shared servers.
I'm not sure if Flash remoting is what I need to get Flash to access the cfc's.
Can someone tell me if I need to switch hosts (which would be a real pain) and look for a host that has Flash remoting or if that is even what I need?
Thanks,
Richie

A bit odd.. I haven't come across any shared hosting with Remoting disabled yet.
Have you tried accessing the remoting gateway?
Should be something like:
http://yourdomain.com/flex2gateway/
You normally get to see a blank page.
If remoting is disabled, you should still be able to access Coldfusion CFC's as webservices.
To achieve this, simply add "?wsdl" to the url of the cfc - without the quotes.
Here's an example:
http://muzakdeezign.com/services/be/pylos/site/NewsSelect.cfc?wsdl
In Flex you access them using a WebService tag instead of a RemoteObject tag.

Trying to make a flex application scalable in its display size by using a "Host-swf" - Problem

We created a flex application using Flex 3. What we are
trying to do is to make this application scalable in its display
size. That means we want the application to scale itself to exactly
fit the size of the browser window without using a scrollbar like
normal Flash-swfs do. Sadly flex application don't scale like a
normal flash swf.
To get a workaround for this we created a so called
"Host-swf" with flash CS3. This Host-swf loads the flex application
and adds it as a child. And voila: When calling the Host-swf our
application can scale.
We used this code to achive this:
var oUrlRequest:URLRequest = new
URLRequest("Flex-Application.swf");
var oURLLoader:Loader = new Loader();
oURLLoader.load(oUrlRequest);
addChild(oURLLoader);
This works perfectly as long the browser window is larger
then the resolution of the host-swf (900*600) when calling the url
for the application:
Picture showing the
scaling
But it doesnt't work out when the browser window is smaller
than 900*600. The application is then shown with a scrollbar, and
when resizing the browser window the scrollbar is still there:
Picture showing the
application with scrollbar
Maybe anyone already tried to achive the same thing and has a
different solution for us?
Thank you in advance!

When I set the Application width and height to a percentage
number, it will
change its size based on the size of the window.

What is necessary for a web host in order to run Flex apps? How to configure?

I did find a few past postings on the forum but none seemed
to address the problem.
Can somebody who had hands on experience share his/her
knowledge about a migrating a Flex application to production
environment? Do I need to modify any settings? When I transfer the
bin folder contents the UI works fine but the data connection
throws errors.
Does the web host need to have any specific software
installed? More specifically, my host has CF 7 but do not have Flex
data services installed. All I use is RemoteObject so I guess this
can be done without Flex data services. Is this correct?
Finally, if you can refer me to a configuration guide that
the web host would need to follow, it would be greatly appreciated.
Thanks for your time in advance.
Emre

Thanks for the response, here is the error message that I am
getting.
(mx.rpc::Fault)#0
errorID = 0
faultCode = "Server.Processing"
faultDetail = (null)
faultString = "Permission denied"
message = "faultCode:Server.Processing
faultString:'Permission denied' faultDetail:'null'"
name = "Error"
rootCause = (Object)#1
cause = (null)
localizedMessage = "Permission denied"
message = "Permission denied"
Obviously some data connection is failing due to permissions.
My host, however, does not know what permisson is causing it and
what the fix would be. Thanks for the input in advance

Invoke windows sound recorder in host machine by flex application

Hi
I have a flex application which provides option to invoke
windows sound recorder in client machine. User provides path of
windows sound recorder exe file and using 'navigateToURL('path of
recorder given by user)' method i plan to invoke the recorder in
client machine.
While executing this code in flex builder it runs properly
and invokes recorder. Then i deployed the flex application in a
server and requested using internet explorer. But this time it does
not invoke recorder. The error messge it displayed is gi ven below
SecurityError: Error #2148: SWF file
http://localhost:8080/flex/bin/DEVM.swf
cannot access local resource C:\WINNT\system32\sndrec32.exe. Only
local-with-filesystem and trusted local SWF files may access local
resources.
at global/flash.net::navigateToURL()
I think it is a security issue of sand boxes. Anyway i tried
to make the directory where exe file is kept (ie. system32) as a
trusted location using 'Global security settings panel'. But that
also did not solve the problem. I think only swf files, not any
other files, in the trusted local directories can be accessed by
the remote flex application. Is it right ???
Anyway i dont wish to keep any swf file under
'local-with-filesystem' sandbox in client machine.
Can anybody please help me to resolve this issue please ....

Hi,
The problem is I am not able to connect to database (11i/R12) from host machine. I am successfully able to run the application from host machine after putting entry in "hosts" file.What is the error?
To connect to database I have installed Oracle 9i client on host machine and put the entry in TNSNAMES.ORA generated by 11i/R12, but even doing so I am not able to connect to database.Are you able to tnsping the entry? If not, what is the error?
Please make sure you also follow the steps in (Note 291897.1 - 11.5.10 New Features : Managed SQL*Net Access from Hosts).
Is there any way I can connect to database (Installed on VMWARE) from HOST Machine.Post the error you get when you connect to the database remotely as well as the output of tnsping command.

Externally Hosted Widgets (Flash object embed) In Catalyst or Flex

Is there any way I can embed flash objects, i.e., externally hosted widgets in FC? ...In Flex?
There are many externally hosted widgets now available for sideshows, video etc, that are flash objects like Cooliris.
( http://developer.cooliris.com/?p=embed/quickstart )
Any suggestions?

Hi Rick,
I am not an expert at this, so I apologize if anything I tell you is wrong. The experts are over on the Flex forums and you'll want to hop over there for deeper questions.
1) To load a SWF from within a SWF, you use the SWFLoader component.
2) FC allows you to embed a SWF within the same project by File > Import > SWF File. In this case, the SWF is compiled into your main SWF and increases its size.
3) To include a SWF that doesn't exist in your project, but that is somewhere else on the internet, you'll need to use FB. There are some cross-domain and security considerations, just like with HTML/JS. Here is the documentation on SWFLoader: http://livedocs.adobe.com/flex/3/html/help.html?content=controls_15.html
Hope that helps =\...

Flex Application Hosting issue unable to access webservice from another machine

Hi all,
I am having a flex application which is using webservice of the asp.net.When I host this application on the machine in which the webservice is present then it works fine.But when I am hosting the application on the another machine then the webservice is not being called.If any body have any idea pls suggest.
Thnx in Advance,
Shardul Singh Bartwal

You may need a crossdomain.xml file. Flex security does not allow your SWF to access data on other domains without it.
In this case even mysub.myCompany.com is considered a different domain from www.myCompany .com.

Web Host For Flex?

Hi Everyone,
This may sound a little bit simple for you Flex experts, but
do I need a special hosting for Flex? What do I need to have to run
Flex apps on my shared hosting account? Do you know any hosting
service that is Flex friendly? Thanks for helping out.

I think :
if its compiled Flex app (.swf) with basic httpServices, it
will work on almost on 99.9% hosting service.
if you want to get sophisticated and use Application service
FDS etc etc with it then you need at least Tomcat web Application
Server , or other compartible server of such nature .

Hosting a Flex Application

Hi, I am an individual Java developer looking to learn, build
and deploy a Flex app. I am a newbie at Flex. So, I have seen
several screencasts and have noticed that the UI would consist of
several .swf files. To host such files or in broader terms, the
Flex app, do I need to use a different hosting solution than those
available for hosting modern web 2.0 applications. Or do I need to
pay adobe again for hosting a flex app? Basically, I am looking at
how cost effective it would be to host a flex app since the IDE
itself costs 250 bucks...

so don't you pay adobe for using their technology in your
website (or for commercial purposes). I am unable to find a good
place to check this out. I may even plan to use Flex Data Services,
Blaze DS....I want to build a commercial web based flex app and
just want to know how much I would need to pay out of my pocket. So
far I know that the IDE costs. I am not sure of Flex Data Services
or Flex Lifecycle....I was able to download a preconfigured tomcat
server with FDS in it but adobe website seems to have trial
versions of it. I wonder if FDS costs too?

Integrating Flex/Flash in Web Dynpro ABAP(Netweaver 7.0) need info!

Hi all,
I need to embed a flash or a flex object inside a web dynpro abap application.I am working in Netweaver 7.0 and i don't have enhancement pack 1 installed.Is it possible ? If it is possible can anyone please provide me the coding and configuration details.
Thanks,
Saikat

I'm afraid that the SAP supplied integration technology - call FlashIslands - is only available from NetWeaver 7.01 and forward. You could perhaps do some simple integration (very little data transfer) with the iFrame UI element - although the iFrame is deprecated in 7.0 and 7.01, but does return to full support in 7.02. The other option would be to use the NetWeaver Portal or NetWeaver Business Client and have two iViews within the page. One iView would have WDA and the other some external technology (BSP, JSP, etc) to host the Flash/Flex content. Not tight integration, but you could potentially use Portal Eventing to at least communicate events.

Flex application not working when deployed run from Server

Hi,
I have Flex application which takes a parameter from user, makes a web-service call and returns the message.
This application is running perfectly when I launch from IDE.
But when I copy the files from bin-release to server and launch it, it gives me no result.
In the crossdomain file on the server which hosts web-service, I have added the my host IP in the
allow-access-from domain tag.
In the initialization method of the application I load crossdomain using following code:
    Security.allowDomain("remoteservername");
    Security.loadPolicyFile("http://remoteservername/crossdomain.xml");
    var request:URLRequest = new URLRequest("http://remoteservername/crossdomain.xml");
    var loader:URLLoader = new URLLoader();
    loader.load(request);
Is there a way I can debug application when running from server?
Please give me some pointer to solve this problem.
Thank you.
Chintan

Alex thanks for reply
The URL for the app is http://<some_IP>/flex_app
<some_IP> is added in crossdomain.
Also we have outbound IP's and of these are also added in the crossdomain file.
This is the current content of crossdomain file:
<cross-domain-policy>
<site-control permitted-cross-domain-policies="master-only"/>
<allow-access-from domain="<some_IP>"/>
<allow-access-from domain="<outbound_IP1>"/>
<allow-access-from domain="<outbound_IP2>"/>
<allow-access-from domain="<outbound_IP3>"/>
<allow-http-request-headers-from domain="<outbound_IP1>" headers="SOAPAction"/>
<allow-http-request-headers-from domain="<outbound_IP2>" headers="SOAPAction"/>
<allow-http-request-headers-from domain="<outbound_IP3>" headers="SOAPAction"/>
</cross-domain-policy>
App runs perfectly fine when launched from Flex Builder.
