TWAIN/WIA implementation for JAVA

I am working on an application(Java Applet) that interacts with scanner. I understand I need a Twain library or WIA library to make it work in windows. But I am not sure what are the differences of two? I am trying to use this library:http://thorntonzone.com/manuals/Com...sc/uk/co/mmscomputing/device/twain/index.htmlJAR file link is broken so I got it from here.http://rsbweb.nih.gov/ij/plugins/twain-scan.htmlAnd DLLs from here: http://sourceforge.net/projects/twain-dsm/?source=dlpBut, it does not detect the source. Here is the error log: http://pastebin.com/cB9gL0ipI am on 64bit machine. Anybody had any success?TWAIN specification is too long to follow and I haven't found any resources on WIA implementation. Any help/pointers/resources is greatly appreciated.
