My query retrieves more than 5000 records from Oracle database. I want to display the records 100 per page. I know it is called pagination. Any detailed styp-by-guide or tutorial or example available?

Here's Tom Kyte's article from several years ago about using ROWNUM and Top-N for pagination in Oracle.
Look for the section "Pagination with ROWNUM" about half way down.

As a side note: I would seriously question the value of presenting over 5000 records on the UI, paginated or not. No user is going to look at every single one.

That's the reason for pagination, surely?
So you're only displaying a subset of the results.

That's what Google does, after all.

I always recommend the jQuery plugin DataTables. It will make this a lot simpler. It does the pagination for you, lets the user select how many records they want displayed, will process the records on the server side returning only as many as need to be displayed, provides column sorting, it's theme-able with jQuery UI and other features too numerous to list.

I'm not associated with the product, I just use it a lot.

I'd suggest only retrieving as many rows as you are yogin to display. Why fetch 5000 rows if you are only going to show 100? There are SQL clauses to "slice" the data that is returned by the result set (depends upon database), and JPA methods to do the same.

Which is exactly what the Ask Tom page I linked to shows you how to do.
Attempting to show everything is a short hop from a padded room and a coat with long arms.

Agreed. And any large data set without filtering ability is a recipe for a straight-jacket.
