in more detailed explanation, wan't create java app have specific file in it's directory. whenever app run, submit 1 file "file" input on website , app call submit button on site. there sort of 2 parts, first there actual website, form , php backend done , works supposed. there external app, can have on desktop. run 1 time , have specific file uploaded, without me having enter website , manually. far haven't been able find much, other apache commons library, said have uploading part.

to make time line go, java app connects url, java app inputs/uploads desired file , java app submits actual form.
