You'll have to send a HTTP POST command through netcat, eg
Code:
(echo 'POST /examples/jsp/dates/nextPageToPost.jsp HTTP/1.1'
echo 'Host: localhost'
echo 'Content-Type: application/x-www-form-urlencoded'
echo
echo 'your data url encoded' ) | nc localhost 80

Please start using [CODE] tags when posting command lines and the like.
Tying 'ne' instead of 'any' saves you exactly 1 character, while making your text much harder to read. Please use correct English if possible.
An lastly, what I posted was a quick, non-tested example to show you how this could be done, and by no means a ready, full functional script. If you want a finished script because you don't want to bother yourself, just tell us so, but then don't expect us to go head over heels for that.
