Question about web based twain scanning using coldfusion

I have an app that is an image viewer, using the java advanced imaging API to read a TIFF from a remote server and output it as a .png and serve it to my end users.  I would really like to add scanning capability to this app, so the end user can directly add images.

My first thought was to setup the end users PC's to scan to a single folder, and upload to the server using a batch file.  Then they could open up as web-based app and have CF pull up each image in a sequence and allow them to add index information to each image, and hit enter.  This would add it to the DB and move the image to a set location.  This would work, but would be cumbersome to the users.

What I want to really know is:  Is there any way to (cross-browser, mostly IE 6+ or firefox latest build) access TWAIN on the local system and allow the user to index the images from the browser as they scan them?

Thanks for any advice or idea's you guys have!

edit:  I have tried a product called DotTwain, but I was unable to get that working the way I wanted too. :(

There are a few solutions:

1) ActivScan : www.cfdev.com/activscan

This product is no longer in development, but you can buy the source code for $995.  From what I knew of colleagues using it, it worked incredibly well.. unless you run into their few cases where errors were occurring.  It seems the source can be fixed, but, once agan, an option, I'm sure you can find lots about it at a good coldfusion list like www.houseoffusion.com

2) Java type component for Twain.

If you are wanting and able to put in the work, searching for a Java Based compnent to control twain would be a great route.  A good article I found was http://www.javaworld.com/javaworld/jw-07-2002/jw-0726-twain.html

It introduces you to the idea, and you could integrate it via a cfx tag, etc.

Hope that helps.

I found a component that would do the trick completely java, called Morena. :)

Glad it was of help -- Java is a great way to go -- less headaches, I hope it works well whether the end user is using microsofts JVM or Sun's Real JAVA .

Good luck, if you have any interesting experiences integrating this with Coldfusion, please post here -- I do all sorts of strange and crazy integration with CF, and this is right up the alley of what i'd like to keep in mind!
