for win2000 + (intellij idea java5) on my home pc, and i try to compile
one of the .java demo programs.

it does not work.

where is the .jar library for .java programs?
what else do i have to do in order to make it work (include library or
startup names)?

if i downloded this db-4.4.20.zip (not java version) can it work with
java programs?
or something must be added?
