defining utf-8 encodage when posting data

defining utf-8 encodage when posting data

Hi all, I'm using the post function to send data. the problem is when I'm sending the data with special characters like é à ù è ..... the server display this characters é à è ù
Does anyone know how i can specify the encodage *. My server side is a tomcat and the page which processing the data is a jsp.
My jQuery  code :
   $.post(
     'addAnnotation.jsp',
      { note: note},
       function(data){
         alert('ok');
        });//end function   

My jsp code :

<%@ page language="java" contentType="text/html; charset=ISO-8859-15" pageEncoding="ISO-8859-15" %>
<%@ page import="java.util.*" %>

<%   
    String note = request.getParameter("note");
   
    System.out.println("--------- note =  " +note); this line display : é à è ù instaed é à è ù

%>
