Map Servlet to Hebrew URL Pattern (UTF-8)

I am on Windows. Using tomcat 8. IDE - Netbeans 8. JDK1.8.0_05

I am trying to specify a Jewish url pattern for specific servlets. (I tried setting the Urlpatternannotation parameter @webservletand putting it in a file web.xml).

Jewish mapping does not work. I check what the mappings look like while Tomcat is running (using the MBeans tab in the JConsole), and the Hebrew url is displayed as gibberish (in particular, question marks).

I tried:

  • Adding -J-Dfile.encoding = UTF-8 to the netbeans.conf file.
  • Change Windows locales to Hebrew.
  • Using the URLEncoded version of url in the template (this also appears as gibberish symbol in JConsole).
  • I also tried to enter the URL into my encoded form in the address bar (for example: localhost: 8080 / test /% D7% A2% D7% 91).
  • I checked the encoding of the servlet files in notepad, they are saved as UTF-8 (after making the first change described in this list).
  • I have a filter on all url samples (for example: "/ *") that sets the request character encoding to UTF-8 (Apache also tried SetCharacterEncodingFilter)

Any suggestions on how I can map the Jewish (UTF-8) url to tomcat, netbeans, java, windows setup?

Thank.

utf-8. Tomcat, URIEncoding="UTF-8" conf/server.xml. :

<Connector port="8080" maxHttpHeaderSize="8192"
 maxThreads="150" minSpareThreads="25" maxSpareThreads="75"

            request.setCharacterEncoding(encoding);
            /**

        response.setCharacterEncoding("UTF-8");
            next.doFilter(request, response);
    }

        public void destroy(){}
}`

  • web.xml

     <filter>
        <filter-name>CharsetFilter</filter-name>
        <filter-class>charsetFilter.classes.CharsetFilter</filter-class>
            <init-param>

  • HTML, :

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fi"> <head> <meta http-equiv='Content-Type' content='text/html; charset=UTF-8' />

  1. :

    request.setCharacterEncoding("UTF-8");
response.setContentType("text/html; charset=UTF-8");
response.setCharacterEncoding("UTF-8");

  2. :
    String input = new String(request.getParameter("foo").getBytes("iso-8859-1"), "utf-8"); String input = URLDecoder.decode(request.getParameter("keyWord"), "UTF-8"); System.out.println(input);

URL:

String str = "$ome UTF-8 text £900";
String url = "http://your-domain.com/url?p=" + URLEncoder.encode(str, "UTF-8");
