<script>
var xmlHttp;
function showState(){
    var str1=document.getElemenetByID("txt1").value;
    var str2=document.getElemenetByID("txt2").value;
    var str3=document.getElemenetByID("txt3").value;

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= "emp.jsp";
url += "?val1=" +str1+"&&val2="+str2+"&&val3="+str3;
xmlHttp.onreadystatechange = stateChange;
xmlHttp.open("GET", url, true);
xmlHttp.send(null);
}
function stateChange(){
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){
var v=xmlHttp.responseText;
var strar = v.split(":");

        document.getElementById("txt1").value= strar[1];
        document.getElementById("txt2").value= strar[2];
        document.getElementById("txt3").value= strar[3];
}
}
</script>
</head>
<body>

<table>
<tr><td>Enter Name:</td><td><input type="text" id="txt1"></td></tr>

<tr><td>Enter Email:</td><td><input type="text" id="txt3"> </td></tr>

<tr><td><input type="button" value="Submit" onclick="showState();"></td><td>

ResultSet rs = stmt.executeQuery( "SELECT * FROM data");
String id="";
               while(rs.next())
                {
                    data = ":" + rs.getString("name") + ":" + rs.getString("address") +":"+ rs.getString("email");
                }
