Question

i am trying to display unicode characters(Chinese) in my application.The jsp part is working fine and has no issues by setting the charset to UTF-8.But in the Java code , Unicode characters are not displayed.I tried by setting the request to utf-8

request.setCharacterEncoding("UTF-8");

Finally i will be getting the same and insert in to the table.The database is already configured for unicode support.

what am i doing wrong.Kindly advice on the solution or is there a better way to do it.

Thanks

Try to implement Filter in your application for character encoding:

public class CharacterEncodingFilter implements Filter {

    @Override
    public void init(FilterConfig filterConfig)
            throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain)
            throws IOException, ServletException {
        servletRequest.setCharacterEncoding("UTF-8");
        servletResponse.setContentType("text/html; charset=UTF-8");
        filterChain.doFilter(servletRequest, servletResponse);
    }

    @Override
    public void destroy() {

    }
}

And if you are using tomcat, make sure that your connector element has URIEncoding attribute which value is UTF-8.

<Connector port="8080" 
           protocol="HTTP/1.1"
           connectionTimeout="20000"
           URIEncoding="UTF-8"
           redirectPort="8443"/>

Also make sure that you specifying this in every JSP page:

<%@page contentType="text/html" pageEncoding="UTF-8"%>

Hope this helps.
