Apache makes a HttpClient library that is really good for this kind of stuff. 
http://hc.apache.org/httpclient-3.x/

It has methods for doing posts, gets and all kinds of other fun stuff :)  And it all happens at a higher level than what it looks like you are trying to do.  

Also, when you are trying to do this stuff Firefox with Firebug can be a huge help.
