I think you should do something like this :

  1. Every page no. should be a link which should contain some parameter which helps the action in determining what page of records is to be shown.

page link should be like 

<a href="<s:url action="getpage">
   <s:param name="pageno" value="4"/>
</s:url>">Page 4</a>

i am not sure what your exact requirement, but for pagination you have to place your logic in your action class which includes

  1. Total Number of records.
  2. Number of records you want to show per pages.

based on above 2 values you will get how many pages you have total.All you need to show them in your jsp and based on the page number you have to calculate the starting record number and the number of record you will fetch.

for showing pages on JSP you have to decide what format you want to have and need to place some sort of if and else statements.

there is nothing like specific to Struts2 and its a generic logic, all dependents upon how you want to implement.

since i believe you will not fetch all the record in one go and will fetch them per page
