UTF-8 encoding in JSP page [duplicate]

Answer 1

This thread can help you: Passing request parameters as UTF-8 encoded strings

Basically:

request.setCharacterEncoding("UTF-8");
String login = request.getParameter("login");
String password = request.getParameter("password");

Or you use javascript on jsp file:

var userInput = $("#myInput").val();            
var encodedUserInput = encodeURIComponent(userInput);
$("#hiddenImput").val(encodedUserInput);

and after recover on class:

String parameter = URLDecoder.decode(request.getParameter("hiddenImput"), "UTF-8");
