Presumably you can get at the twain driver from C++ and you have docs
and a driver to do that. So some of your JNI choices are:

1. write a Java wrapper around every Twain function and do your work
from Java.

2. write a custom getDocument in C++ and invoke it is Java. It is not
general purpose.

3. Invent a higher-level interface for Java, pass the parms to C++ and
do the lower level twain stuff there.

My preference would be for (3) unless it turned out that Twain was
higher level than I would expect.
