Can anybody tell me how to done paging in jsp... :)

I assume you are referring to pagination and sorting which is sometimes called paging... if so, the Display tag library (Display tag library - Overview) is a useful resource for doing such. There is also the JSP Pager tag library (<jsptags> Pager Tag Library). I played around with the first one (the Display taglib) a few years ago, but have never used either extensively, so I cannot say which might be better. But the first one (the Display taglib) appears to be a bit better documented and is a mature library and project.

Finally, the article "Pagination using JDBC and JSP" discusses the subject. Try Googling the term pagination in JSP for more resources.
