I am currently writing a small web server, and I tested your request client. My server is receiving the following request:

User-Agent: Java/1.6.0_20 
Host: localhost:1700 
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2 
Connection: keep-alive 
Content-type: application/x-www-form-urlencoded 
Content-Length: 287

You should check the format of the POST data you are sending, most probably it is not processed by the server as you would expect.
