Any code samples or ideas would be appreciated.

Please show us your JSTL code. Maybe we can work from there.

Pleease find the snippet of code below used to dispaly the whole list of comments.

<c:if test="${null != blogessay.comments && not empty blogessay.comments}" >
                                                
<h1 class="commentHeader">COMMENTS</h1>
<!-- begin comment (repeat as necessary) -->
      <c:forEach var="comment" items="${blogessay.comments}" varStatus="commentCounter">
            <fmt:parseDate var="dateObj" pattern="yyyy-MM-dd HH:mm:ss.S" value="${comment.lastUpdateDate}" />

<!-- begin comment (repeat as necessary) -->
            <div class="commentDetails">
                  <div class="commenter">
                  <img src="<c:out value="${comment.avatar}" />" alt="" />
                  <div class="label"><c:out value="${comment.userName}" /></div>
            </div>
      <div class="essayComment">
            <span class="bold">POSTED ON:</span> <fmt:formatDate pattern="MMM dd, yyyy hh:mm aaa" value="${dateObj}" /><br />
            <div class="commentActions">
                  <a class="flagit" href="#" onclick='javascript:confirmFlagComment(<c:out value="${comment.ID}" />)'>Flag it</a>
            </div>
      </div>


<div class="commentText">
      <p><c:out value="${comment.commentText}" escapeXml="false" /></p>
</div>
                                          

</div>
<div class="clear"></div>
<c:if test="${!commentCounter.last}" >
</c:if>
<!-- end comment (repeat as necessary) -->
      </c:forEach>
</c:if>

If you want to write your own, then it is kind of difficult,
but you can use existing tag lib like

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Use display tag library its very cool with JSTL.
http://displaytag.sourceforge.net/1.2/

a very simple library to play around with.

karanw and Murali have made good suggestions.   But, if you just want something simple, then you could use something like the test JSP below here.  If you have any troubles or you need to tweak it, then ask us for help.  
<%@ page import="java.util.*" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> 
<%
   List<String> comments = Arrays.asList("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z");
%>
<c:set var="comments" scope="session" value="<%=comments%>"/>
<c:set var="totalCount" scope="session" value="<%=comments.size()%>"/>
<c:set var="perPage" scope="session"  value="4"/>
<c:forEach var="boundaryStart" begin="0" end="${totalCount - 1}" step="${perPage}">
         <a href="?start=${boundaryStart}">[${boundaryStart} - ${boundaryStart + perPage - 1}]</a>
</c:forEach>
<c:if test="${null != comments && not empty comments}" >                                                
<h1 class="commentHeader">COMMENTS</h1>
   <c:forEach var="comment" items="${comments}" varStatus="commentCounter"
                            begin="${param.start}" end="${param.start + perPage - 1}">
       <div class="commentDetails">
                  <div class="commenter">
                          <div class="label">${comment}</div>
                  </div>
         <div class="essayComment">
            <span class="bold">POSTED ON:</span> <fmt:formatDate pattern="MMM dd, yyyy hh:mm aaa" value="${dateObj}" /><br />
            <div class="commentActions">
                  <a class="flagit" href="#" onclick='javascript:confirmFlagComment(${comment})'>Flag it</a>
            </div>
         </div>
       </div>
   </c:forEach>
</c:if>

Thanks Karan and Murali. The above code snippet is sufficient for my requirement, but I am trying to make some modifications to the code that so that I can get the list as 1-10 and the button next (>) to display the next 10 items and button to go to previous(<). Please let me know if you have any immediate thoughts to do some thing like this.

just some thing like this 1-10  of 80  : »

thanks,
Kalam

Here is what I did tonight. If you need more help, then tell us. Maybe I will have more time tomorrow.  
<%@ page import="java.util.*" %>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

   List<String> comments = Arrays.asList("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z");
%>
<c:set var="comments" scope="session" value="<%=comments%>"/>
<c:set var="totalCount" scope="session" value="<%=comments.size()%>"/>
<c:set var="perPage" scope="session"  value="10"/>
<c:set var="pageStart" value="${param.start}"/>
<c:if test="${empty pageStart or pageStart < 0}">
       <c:set var="pageStart" value="0"/>
</c:if>
<c:if test="${totalCount < pageStart}">
       <c:set var="pageStart" value="${pageStart - 10}"/>
</c:if>
        <a href="?start=${pageStart - 10}"><<</a>${pageStart + 1} - ${pageStart + 10} <a href="?start=${pageStart + 10}">>></a>
<c:if test="${null != comments && not empty comments}" >                                                
<h1 class="commentHeader">COMMENTS</h1>
   <c:forEach var="comment" items="${comments}" varStatus="commentCounter"
                            begin="${pageStart}" end="${pageStart + perPage - 1}">
