I have figured out how to have my action class be called whenever user click on a page index(solution is to have url="/rootcontext/paymentHistory.do"). So the first question I asked below is solved.
Now I encountered another problem. When user click on the 10th page(Please see the following senario for detail), the first 500 records will be removed from session, and the next 500 records will be retrieved from DB, and displayed to user. From logic view of point, the second 500 records should be displayed from page 11-20. But now, the page number still shows 1-10, and only the last records on 10th page is from second 500 records(the last record). The rest of the records dispalyed are still from the first 500 records. This is not correct. My question: How can I have the page index to be displayed correctly, and works correctly? Thank you very much for your help.

I have a question about using jspTags pager(http://jsptags.com/tags/navigation/pager/ ). Anand, I am sorry to send this email to you directly. I know you are expert on using jspTags pager. I urgently need your help. I hope you can recieve my email, and help me! If someone has used the jspTags pager before, please help me!! I am stunk here. Senario: There are lot of payments history records for a user. I will retrieve 500 records from DB at one time, and put them into session. When the next 500 records are retrieved, they will replace the first 500 records in the session. For example, if a user have 1200 records totally, at first time, the first 500 records will be retrieve from DB. To display the records, I use jspTags pager (http://jsptags.com/tags/navigation/pager/). On one page, 50 records will be displayed. So the first 500 records will be displayed on 10 pages. When user click on the last page(10th page), I want the next 500(501-1000) records to be retrieved, replace the first 500 records in the session, and then to be displayed to user. To achieve this, in my action class, I need to keep track the page number that the user click on.When the action class find that the last page(10th page) is clicked, The next 500 records will be retrieved, and be displayed to user. My Jsp name: paymentHistory.jsp My status and problem: The first 500 records can be displayed on 10 pages correctly. When I click on the page index(for example, I click on page "2"), the URL changed to http://..../rootcontext/paymentHistory.jsp?pager.offset=50. BUT MY ACTION CLASS IS NEVER BE CALLED.I AM STUNK HERE!!! My question: 1. How can I make the my action class to be called whenever user click on a page index?( I tried put <html:form action="paymentHistory.do"> in my paymentHistory.jsp. but it shows same result. So I guess when user click on page index, it does not submit the form). 2. How can I pass "pageNumber" as a request parameter? (I tried put <pg:param name="pageNumber" /> inside <pg:pager>. It doesn't show pageNumber on URL. I also tried to put "?number=<%= pageNumber %>" in the line <a href="<%= pageUrl %>?number=<%= pageNumber %>"><%= pageNumber %></a>. It doesn't work.
