Question

I am currently working on a Bilingual application (English and Arabic) with struts framework.

My application is currently built to support English characters.

Now am trying to post and read UTF-8 encoded characters on my JSP pages in Tomcat 6 environment.

So i have the basic things set up in all my jsp pages and action class.

I have set this in my action class

            `request.setCharacterEncoding("UTF-8");
    response.setCharacterEncoding("UTF-8");
    response.setContentType("UTF-8");`

In my jsp pages: <%@page pageEncoding="UTF-8"%>
<%@page language="java" contentType="text/html;charset=UTF-8"%>

So when i try to post Arabic characters to my jsp page, it displays junk characters.

How do i correct it? what else do i need to do to support arabic or chinese characters?

Also, am using a database to save the form once the user fills out the application. The user can either use English or arablic to fill the form.

How do i achieve this?

Answer 1

You need to do only two things to get UTF-8 to work for POST forms.

Put this in top of JSP:

<%@ page pageEncoding="UTF-8" %>

Put this in a Filter which runs before your action class.

request.setCharacterEncoding("UTF-8");

Doing this inside the action class might be already too late. It should be set before you or any MVC framework gathers the request parameters.
