Subject Re: How to control encoding of response.sendRedirect? (Tomcat 5.5.17)
Date Fri, 22 Sep 2000 13:19:15 GMT
good
point-http://java.sun.com/developer/technicalArticles/Intl/HTTPCharset/index
-011206.htmlsuggests a webapp solution to embed the encoding param in
web.xml e.g.<context-param>
  <param-name>PARAMETER_ENCODING</param-name>
  <param-value>UTF-8</param-value>
</context-param>/*This way you can read the param for input request */
private String encoding;
    public void init() throws ServletException {
        ServletConfig config = getServletConfig();
        encoding = config.getInitParameter("PARAMETER_ENCODING");
    }

/*as well as accomodating the output response*/
   protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
    throws ServletException, IOException {
        if (encoding != null) {
            request.setCharacterEncoding(encoding);
        }
        ...
    }
    protected void doGet(HttpServletRequest request, HttpServletResponse
response)
    throws ServletException, IOException {
        processRequest(request, response);
    }

    protected void doPost(HttpServletRequest request, HttpServletResponse
response)
    throws ServletException, IOException {
        processRequest(request, response);
    }
