First, you need to tell the browser that you're serving UTF-8 content and expecting UTF-8 submit. You can do that by either placing the line in the very top of your JSP,

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

or by adding the following entry to web.xml so that you don't need to repeat @page over all JSPs:

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <page-encoding>UTF-8</page-encoding>
    </jsp-property-group>
</jsp-config>

Then, you need to tell the servlet API to use UTF-8 to parse POST request parameters. You can do that by creating a servlet filter which does basically the following:

@WebFilter("/*")
public class CharacterEncodingFilter implements Filter {

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        req.setCharacterEncoding("UTF-8");
        chain.doFilter(req, res);
    }

    // ...
}

That's all. You do not need <form accept-charset> (that would make things worse when using MSIE browser) and you do not necessarily need <meta http-equiv="content-type"> (that's only interpreted when the page is served from local disk file system instead of over HTTP).

Beware that when you're using System.out.println() or a logger in order to verify the submitted value, that it should in turn also be configured to use UTF-8 to present the characters, otherwise you will be mislead by still being presented with Mojibake.

can you tell me what worst thing happened? – Netorica Feb 26 '13 at 13:55
value "multi章byte" is passed to server. but in server, it is receiving as "multiç« byte" – user760658 Feb 26 '13 at 13:56
it is passed as POST? and read using `request.getParameter()`? – Netorica Feb 26 '13 at 14:00
yes, it is passed as POST and read using request.getParameter() – user760658 Feb 26 '13 at 14:00
