I was wondering if there is any way to bring up a scanners software using java. Basically I want to be able to have a user click on a "scan in document" button and then whatever scanner is installed on the users PC will come up asking for scan options and etc.
You could have a look at this question What libraries do I need to use a paper scanner in java?
But basically, depending on the platform you're aiming for you could try
or try Morena
I've used Morena in the past and found it very easy to use, but I'm waiting for there WIA implementation to be completed
