Hi Kesava

If i am not wrong u want something like google shows after results.

It is quite a simple thing in Jsp

Have u hearsd abt Display taglib just download that from net

And u can use the following code for displaying ur records in pages

<display:table name= ur vector name which is comingin form or Request class="Data" id="row" requestURI="the class u r coming from " pagesize="5">
<display:column property="property of the object in list" title="Any heading for the column" />
</display:table>

try this out u have to download the tld for display that u will get on Sourcrforge.net or opensymphony.com

any futher help u can post here agian

Best Regards
Pankaj

take a look at the JSTL c:forEach tag which is the standardised way to do paging.

Try this very simple �..
File.jsp
========
<html>
<%
java.util.ArrayList a = new java.util.ArrayList();
for(int i = 0;i < 45;i++){
a.add(String.valueOf(i));
}
session.setAttribute("data",a);
%>

<jsp:forward page="another.jsp?status=0"/>

</html>
Another.jsp
============
<html>
<%
String status = request.getParameter("status");
int intVar = Integer.parseInt(status);
java.util.ArrayList al = (java.util.ArrayList)session.getAttribute("data");
%>
<form name="form1">
<table>
<%
for(int i = intVar*10;i<intVar*10+10;i++){
%>
<tr>
<td>
<%=al.get(i)%>
</td>
</tr>
<%
}
%>
</table>
<input type="button" value="next" >
<input type="text" value="<%=status%>" name="val">
</form>
<script>
function next(){
cp =parseInt(document.form1.val.value);
cp++;
window.location="another.jsp?status="+cp;
}

</script>
</html>
