Jody,
As a new user/participant on the list I hate to cause waves, but I notice that
a lot of the documentation might as well be Greek to me. I mention it here
because this question seems to be a really good example of what I'm talking
about. Jean Marie asked a question about determining the distance from a point
to a line and it is listed in the documentation under "Using SpatialIndex and
LocationIndexLine to Snap points". I might be because I'm new to the project,
but my initial thoughts on this page when I saw it before was that it had to do
with GUI functionality (snapping frames/panes/windows).
I know a lot of people have put a lot of time into producing the documentation
that we have, but one of the things I find the most offsetting about the entire
project is the fact I can drown in documentation without ever having an idea
what I'm doing wrong.
I apologize in advance for any toes I may have stepped on. I would be willing
to help with updating the documentation, but I don't know nearly enough about
how the library (or GIS) works.

That functionality is provided by JTS (the library we use for geometry).
Since this is a common question we have it covered in the user guide:

hello
is there an easy way with Geotools to get the closest distance
between a point and a line (this line being specified by 2 points)
thanks in advance
