To get the value of a form field or parameter value of a query string, use the getParameter() method of the request object.

url: www.teste.com?parametro=teste

How to get the value in the servlet:

String param = request.getParameter("parametro");

If the value is an integer or another type, a type conversion is required because the http protocol works only with text or everything is a string.
