Hi ,
I have this link in jsp which has below tags,
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<a href="TestServlet?teststring=testing&testing1">Testing</a>
and then my servlet looks like below,
/*
* To change this license header, choose License Headers in Project
Properties.
* To change this template file, choose Tools | Templates
* and open the template in the editor.
*/
package controller;
import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
/**
*
* @author Kiran
*/
@WebServlet(name = "TestServlet", urlPatterns = {"/TestServlet"})
public class TestServlet extends HttpServlet {
/**
* Processes requests for both HTTP <code>GET</code> and
<code>POST</code>
* methods.
*
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
/* TODO output your page here. You may use following sample
code. */
String param = request.getParameter("teststring");
String param1 = new
String(request.getParameter("teststring").getBytes("UTF-8"));
out.println("<!DOCTYPE html>");
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet TestServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet TestServlet at " +
request.getContextPath() + "</h1>");
out.println("<h1>Servlet TestServlet at " + param + "</h1>");
out.println("<h1>Servlet TestServlet at " + param1 + "</h1>");
out.println("</body>");
out.println("</html>");
}
}

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
processRequest(request, response);
}
}
and getParameter for some reason seems to truncating the value after &
Servlet TestServlet at testingServlet TestServlet at testing
I really need to understand as what characters are accepted and what
characters get truncated with getParameter.
I am building few links on the fly which might have space,backslashes,
comma and & characters in it.So wanted to understand should I encode it via
js or container can take care of those for me.
container connector setting has URIEncoding="UTF-8" settings.
Thanking you
Kiran Badi
