Manually submit a form without using javascript?

Question

i'm trying to automate registration of a site by using java (no gui). However there is no direct submit button or form.submit() present in its registration url. Checked the javascript codes and it opens a window, and checks if the window opener is present .
if (window.opener && !window.opener.closed)
window.opener.document.theForm.submit();
window.close();               
}Is there a solution for this problem?

I'm trying to access an http url (not mine).
(1) By setting post variables , I can retrieve the html of the url as string. Here's the code.
     static String getHtml(String url_nm, HashMap variables)
          String html = "";
          String data = "";
          boolean firstRun = true;
          if (variables != null)
               Set keys = variables.keySet();
               Iterator iterator = keys.iterator();
               while (iterator.hasNext())
                    if (firstRun)
                         firstRun = false;
                    else
                         data += "&";
                    String name = iterator.next().toString();
                    try
                         data += URLEncoder.encode(name, "UTF-8") + "=" +
                              URLEncoder.encode(variables.get(name).toString(), "UTF-8");
                    catch (Exception e1)
          try {
             URL url = new URL(url_nm);
             URLConnection conn = url.openConnection();
             conn.setDoOutput(true);
             OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
             wr.write(data);
             wr.flush();
             BufferedReader rd = new BufferedReader(new InputStreamReader(conn.getInputStream()));
             String line;
             while ((line = rd.readLine()) != null) {
                  html += line;
             wr.close();
             rd.close();
         } catch (Exception e) {
              e.printStackTrace();
          return html;
[/code
(2) The problem is even if i set the post variables, i cannot submit the form since the form can only be submitted if i was actually browsing it in a web browser. The html displays a window where the actual submit  form is set (as you can see in my later post) .
