I have a problem sending special characters like cyrillic or umlauts from a jsp to a servlet. I would greatly appreciate your help here.

Here is what I have done:

  1. Defined the utf-8 charset in the jsp:

    <%@ page language="java" contentType="text/html; charset=utf-8" 
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" 
"http://www.w3.org/TR/html4/loose.dtd">
<html>
 <head>
  <meta http-equiv="content-type" content="text/html; charset=utf-8" />
 ...

<div class="authentication">
  <form name="registerForm" action="register" method="get" accept-charset="UTF-8">
    <input type="input" name="newUser" size="17"/>
    <input type="submit" value="senden" />
  </form>
</div>
 ...

  2. Set Tomcat URIEncoding for Connector, in the server.xml

    <Connector URIEncoding="UTF-8" ...

  3. Inside the servlet - set the CharacterEncoding to UTF and read request

    public void doGet (HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException{

request.setCharacterEncoding("UTF-8");
String username = request.getParameter("newUser");
System.out.println("encoding: "+request.getCharacterEncoding());

System.out.println("received: "+username);

  4. Here is what gets displayed when using for example: Однако

    encoding: UTF-8
received: ??????

Am I missing something ? I suppose the servlet can not decode the String properly, but I have no idea why is this happening. I've followed all the advises on this topic but had no luck.

thanks in advance.

Everything looks fine. Only the System.out.println() console also needs to be configured to interpret the byte stream as UTF-8.

If you're sitting in an IDE like Eclipse, then you can do that by setting Window > Preferences > General > Workspace > Text File Encoding to UTF-8. For other environments, you should be more specific about that so that we can tell how to configure it.

  • I have already set this. But it does not work for me. Any other settings ? – Kaushik Lele Jul 22 '15 at 10:11

    @KaushikLele: then you don't have the same question as the OP. Look for a different one or ask a new one. I can't do much else than giving you this link so you can finally understand the world of bytes and characters and can nail down further all on your own: http://balusc.blogspot.com/2009/05/unicode-how-to-get-characters-right.html – BalusC Jul 22 '15 at 10:15
