Ok i have found a solution regarding my problem. I have three text boxes in my jsp page, when i am entering any data on first text box then control is going to get.jsp to retrieve data from database and is filling 2nd text box. But I want that data will go from first and second text boxes at a time to get.jsp to auto fill 3rd text box , but i was trying but data was going individually from either 1st or 2nd text boxes.

—-auto.jsp———-

<%@page import="java.sql.*"%>
<html>
<head>  
<script language="javascript" type="text/javascript">  
var xmlHttp  
var xmlHttp
function showState(str){ 
if (typeof XMLHttpRequest != "undefined"){
xmlHttp= new XMLHttpRequest();
   }
   else if (window.ActiveXObject){
xmlHttp= new ActiveXObject("Microsoft.XMLHTTP");
    }
if (xmlHttp==null){
alert ("Browser does not support XMLHTTP Request")
return
} 
var url="get.jsp";//goes to get.jsp
url += "?count=" +str;
xmlHttp.onreadystatechange = stateChange;
xmlHttp.open("GET", url, true);
xmlHttp.send(null);
}
function stateChange(){   
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){   
document.getElementById("country").innerHTML=xmlHttp.responseText;  
}   
}   
</script>  
</head>  
 <body>  
 <input id="name" type="text" name="name" onkeyup="showState(this.value)">
<br>  
<div id='country'>  
</div>  
</body> 
</html>

——–get.jsp————-

<%@page language="java" import ="java.sql.*" %>  
 <%  
 String name=request.getParameter("count");  
 String buffer="<div>";  
 //Got value from database 


while(rs.next()){
buffer=buffer+rs.getString(2)+"<br>";  
}  
buffer=buffer+"</div>";  
response.getWriter().println(buffer);  
%>

Here by request.getParameter(“count”); I am getting only one text box value, but how can i get multiple value from auto.jsp by entering data in first and second text boxes.

    Just call the showState() function on your onkeyup and in the javascript function append the textbox’s value.

    var url="get.jsp";//goes to get.jsp
url += "?count=" +document.getElementById(<first textbox's id>).value;
url += "&secondVal="+document.getElementById(<second textbox's id>).value;

    and you can get the value like you did

    String secondVal=request.getParameter("secondVal");
