Hi Andrew
Thanks for your inputs. The flow which I have been able to achieve till now is :
1. An MXML file which calls a JS function embedded inside it (I was able to accomplish this using Abdul Qabiz's _javascript_ injector component).
2. The JS function opens a new HTML (popup) page which inturn has Applet tags to launch the applet which does the job of scanning.
3. To upload the scanned image, I have written a servlet. The applet converts the java.awt.image object into a ByteArray and then by putting it into a serialized object, I am able to send the image to the server.
But is there a way to invoke the applet without having an HTML file to call it? That is, instead of Flex --> JS --> new HTML popup --> JTwain Applet, cant we just have Flex --> JS --> Applet ?
Your thoughts on this ?
Thanks, Rohan.
