You need to build it manually from the ServletRequest.

StringBuilder sb = new StringBuilder("?");
for (Enumeration e = request.getParameterNames();
   e.hasMoreElements();)
{
      String param = (String) e.nextElement();
      sb.append(param)
        .append("=")
        .append(request.getParameter(param))
        .append("&");
}
String queryString = sb.toString().
   substring(0, sb.length() - 1);

// Create query string

String queryString = "param1=" +
   URLEncoder.encode(param1Value, "UTF-8");
queryString += "&param2=" +
   URLEncoder.encode(param2Value, "UTF-8");

// Make connection

URL url = new URL("http://www.objects.com.au/");
URLConnection urlConnection = url.openConnection();
urlConnection.setDoOutput(true);
OutputStreamWriter out = new OutputStreamWriter(
   urlConnection.getOutputStream());

// Write query string to request body

out.write(queryString);
out.flush();

// Read the response

BufferedReader in = new BufferedReader(
   new InputStreamReader(urlConnection.getInputStream()));
String line = null;
while ((line = in.readLine()) != null)
{
   System.out.println(line);
}
out.close();
in.close();
