Call a Servlet via POST from a Stand alone Java App

Question

Hi guys.
Right now I am facing a tricky problem I hope you can help me on this...
What I want to do is to call a servlet that is listening ( I can't touch the servlet code) in a web browser.
I was able to send a GET request by a code like this:
URLConnection conn = new URL(webServerStr).openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(webServerStr);
wr.flush();
and everthig was all right.
The problem arises when I try to send a long REQUEST via my java app. I get a 414 HTTP error (414 - Request-URI Too Large ). When I do the long request by browser works fine. (when I fill all the form and press the submit button)
The only difference between the browser request and my java request is the ACTION. From the FORM is POST and when I build the string to send it out to the web server is via GET ( I build the string like ?ATTR=VALUE&ATTR2=VALUE2....)
Here is my question. How I do a POST request from a java application?
Any ideas?
Thaks guys and any help will be appreciate.

URL url = new URL("http://localhost:8080/");
HttpURLConnection con = (HttpURLConnection)url.openConnection();           
con.setStuff(...............................check out api
con.setDoOutput(true);
con.connect();
// write stuff
PrintWriter pw = new PrintWriter(con.getOutputStream());
pw.println(depart);
pw.flush();
pw.close();
// read reply
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
String res = br.readLine();
