      1. Set the following in web.xml

        <request-character-encoding>UTF-8</request-character-encoding>
  <response-character-encoding>UTF-8</response-character-encoding>

      2. Create a servlet like the following

      @WebServlet("/test")
public class TestServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException {
        res.setContentType("text/plain");
        PrintWriter pw = res.getWriter();
        pw.println("REQ_CHAR_ENC = " + req.getCharacterEncoding());
        pw.println("RES_CHAR_ENC = " + res.getCharacterEncoding());
    }
}

      3. Running the servlet produces the following output.

      REQ_CHAR_ENC = null
RES_CHAR_ENC = ISO-8859-1
      Show
      1. Set the following in web.xml <request-character-encoding> UTF-8 </request-character-encoding> <response-character-encoding> UTF-8 </response-character-encoding> 2. Create a servlet like the following @WebServlet( "/test" ) public class TestServlet extends HttpServlet { @Override protected void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException { res.setContentType( "text/plain" ); PrintWriter pw = res.getWriter(); pw.println( "REQ_CHAR_ENC = " + req.getCharacterEncoding()); pw.println( "RES_CHAR_ENC = " + res.getCharacterEncoding()); } } 3. Running the servlet produces the following output. REQ_CHAR_ENC = null RES_CHAR_ENC = ISO-8859-1

      The default encoding settings in web.xml does not work on JBoss EAP 7.4.z. This is backport request for WFLY-16584.
