Extracting Request Parameters from a POST.

Question

A client is POSTING some request parameters as part of its POST request.
My servlet is getting this as part of the getInputStream.
The contents of the inputStream received is:
username=someUserName&password=somePassword
Now how do I extract this username and password which is in the Body
of the POST?
I am trying request.getParameter("username")
but am not getting the value of the username.
Can some please help me as to how to get the request parameters?
Attached is my servlet
public class DeviceLocation extends HttpServlet {
private static final String CONTENT_TYPE = "text/html";
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
System.out.println("Servlet up and running...");
InputStream requestInputStream = request.getInputStream();
InputStreamReader isr = new InputStreamReader(requestInputStream);
BufferedReader br = new BufferedReader(isr);
String line = "";
StringBuffer sb= new StringBuffer();
while ((line = br.readLine()) != null)
sb.append(line);
br.close();
System.out.println(sb.toString()); // display the input Stream
// Display all the Request Parameters
System.out.println("Request Method : " + request.getMethod());
System.out.println("Host : " + request.getHeader("Host"));
System.out.println("User Agent : " + request.getHeader("User-Agent"));
} // End of servlet class.

Answer 1

try doing it without reading in the requestInputStream first:
public class DeviceLocation extends HttpServlet {
private static final String CONTENT_TYPE = "text/html";
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
System.out.println("Servlet up and running...");
// Display all the Request Parameters
System.out.println("username Parameter : " + request.getParameter("username"));
System.out.println("Request Method : " + request.getMethod());
System.out.println("Host : " + request.getHeader("Host"));
System.out.println("User Agent : " + request.getHeader("User-Agent"));
} // End of servlet class.
