A very successful approach I've used is to provide the user
only pick lists or combo boxes (HTML OPTION lists) to select
the values from; the servlet creates the page dynamically,
using the table values as the options list.
I've also, in dedicated client apps, built it so a choice of
one option "switched" or requeried the other selections to
valid contents based on the first selection. That limits the
number of invalid entries tremendously and helps data
normalization.
