Ajax

function ajaxFunction() {
  if(xmlhttp) { 
   var txtname = document.getElementById("txtname");
    xmlhttp.open("POST","Namelist",true);

    xmlhttp.onreadystatechange  = handleServerResponse;
    xmlhttp.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded');
    xmlhttp.send("txtname=" + txtname.value); 
  }
}

function handleServerResponse() {
   if (xmlhttp.readyState == 4) {
     if(xmlhttp.status == 200) {
       document.getElementById("message").innerHTML=xmlhttp.responseText;
     }
     else {
        alert("Error during AJAX call. Please try again");
     }
   }
}

jsp

<form name="fname" action="Namellist" method="post">

    Select Category :
    <select name="txtname" id="txtname">
     <option value="Hindu">Hindu</option>
     <option value="Muslim">Muslim</option>
     <option value="Christian">Christian</option>
    </select>
    <input type="button" value="Show" id="sh" onclick="ajaxFunction();">
    <div id="message">here i want to display name</div><div id="message1">here i want to display meaning</div>
    </form>

servlet

String ct=null;  
ct=request.getParameter("txtname");
      Connection con=null;
      ResultSet rs=null;
      Statement st=null;
try{
con=Dbconnection.getConnection();
PreparedStatement ps=con.prepareStatement("select name meaning from (select * from namelist order by dbms_random.value)where rownum<=20 and category='+ct+'" );
rs=ps.executeQuery();

 out.println("name" + rs);
 **Here I have confusion,**

}
catch(Exception e)
{
    System.out.println(e);
}
