Integration with picture scanner 3

[rekenaar]

Hello

I just want to know if anyone here has had any experience regarding interfacing a Java application with a scanner?

Basically what I want to do is have a user click a button on a Java app that will let it automatically scan a document that is in the scanner. Then it must take the picture file and insert it into a database (as a blob or binary or whatever).

Has anyone done something similiar? Know of any guides/tutorials regarding this?

Any information will be appreciated.

By the way: This will only need to work under Microsoft Windows.

From my experience, unless the scanner has a kind of API, you'll need to interface with the native libraries of the scanner through JNI.

Cheers,

I have never tried this before; maybe javax.comm packages might be useful here.
CommPortIdentifier,SerialPort events

I don't think that's the way to go: that would involve implementing the communication protocols and would only work with serial port on Unix or Solaris.

There's a native library called twain that can give you access to the scanner. Morena is an esay interface to twain.

The first link is quite useful, thanks

Thanks for the replies.

That twain native library is exactly what I need.

Thanks!

By the way here is a link to an article that also includes free source code to interface twain and Java. I found it quite helpful. The commercial applications does seem to be more polished and feature complete, but I will investigate to see if they are really necessary for my needs.
