      Hi,

       

      i have written this in jsp

      ---------------------------------------------

       

       

      <%@page import="com.sun.org.apache.xerces.internal.impl.xs.identity.ValueStore"%>

      <%@ page language="java" contentType="text/html; charset=ISO-8859-1"

          pageEncoding="ISO-8859-1"%>

      <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

      <html>

      <head>

      <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

      <title>Insert title here</title>

      <script type="text/javascript">

      function getvalue(){

        var elems = document.getElementsByTagName('input');

        var values = [];

        for(var i=0; i< elems.length; i++){

        if (elems[i].type == "text"){

        values.push(elems[i].value);

        }

        }

        for(var i=0; i< values.length; i++){

        alert(values[i]);

        }

        request.setAttribute("res",values);

      }

      </script>

      </head>

      <body>

      <form action="checkbox">

      <table>

      <tr>

      <td>First Name:<input type="text" name="first"  id="text1"/></td>

      <td>Second Name:<input type="text" name="second"  id="text2"/></td>

      <td>check both<input type="checkbox" id="chk" name="allValue" value="<%=request.getAttribute("res")%>" onclick="getvalue()"/>

      </td>

      </tr>

      <tr><td><input type="submit" value="OK" ></td>

      </tr>

      </table>

      </form>

      </body>

      </html>

       

       

      And Servlet Code

      --------------------------

       

      package com.test;

       

       

      import javax.servlet.http.HttpServlet;

      import javax.servlet.http.HttpServletRequest;

      import javax.servlet.http.HttpServletResponse;

       

       

       

       

      public class TestServlet extends HttpServlet {

       

       

        protected void service(HttpServletRequest req,HttpServletResponse res)

        {

        String[] str=req.getParameterValues("allValue");

        for(int i=0;i<str.length;i++)

        {

        System.out.println("checkbox:"+str[i]);

        }

       

        }

      }

       

      ----------------------------------

       

      here i am getting null value in servlet even though i have set the all textbox values in request in javascript function as i have written in above code

       

       

      please suggest me if any solution is there

       

      Thanks,
