Java programmers all seem to think that running an image generating process in
a web
browser window on the server is bad practice. So I think I might just go
ahead and
compile it as an AIR app. I'm not sure though how to deploy AIR apps though.
Can they
go in a .war file?
If someone has any ideas about this or if there is an aircoders list that
might better
answer this question or if going AIR is the wrong approach here please let me
know.
Thanks!

I am using the following method to save the image:
private function captureImg(comp:UIComponent, name:String):void {
var imageSnap:ImageSnapshot =
ImageSnapshot.captureImage(comp);
var imageByteArray:ByteArray = imageSnap.data as ByteArray;
imgSave.saveImage(imageByteArray, name+-img.png);
}
imgSave is a RemoteObject java class. The problem is that the flex app which
runs this
code never gets launched on the server. When I try to launch it from java
with a runtime
exec and the URL, it never launches, presumably because it is running in a
browser and
the server is headless. That's why I am considering reconfiguring flex to
run headless
or
converting it into an AIR app.

actually not need air app to do that, You can use the bytearray to encode
the image and send to your java to save that each time or in meanwhile you
need.

feedback I am getting is that it is bad practice to run flex in the
browser
for a background
app.
Here's what the program does in a nutshell:
The server launches my java app. It reads a list of report definitions
from
the data base. For
each report, it spawns a thread. Each thread launches my Flex application
in the browser.
Flex draws the data in charts. Each time data is pushed to the flex
application from the java
server side, Flex calls a remote java method to save it's image to a file.
This file sits in a
directory where it can be viewed in a regular old html page.
The problem is really the automated aspect. I want to have this chart
generated every few
minutes as a .png file. It works perfectly fine on my localhost machine,
but the server
deployment is so far not working. We have firefox installed on the server.
Is there no way to
launch it as a background process to draw these images? Should I turn this
into an AIR app
(I've never done anything with AIR up to this point) to make it run more
easily in the
background?
