how to write a pager in velocity??

[Inandjo Taurel <in...@hotmail.com>]

hi,

am trying to write a pager in velocity screens so as to have my screens 
displays only a defined number of rows on the screen, and then be able to go 
to the next set of result set and the previous, just by clicking the link.
How can i achieve that in the context of velocity?

PS: am using TDK 2.1 with jdk1.3.1..

You can either use Criteria objects to set a limit and offset for the
rows you are returning, and make two queries; one for the actual data
and one for the number of total rows. Then you can do some math given
how many rows you want to display on a page and generate links that
have the offset and limit as parameters. 

A better way may be the org.apache.torque.util.LargeSelect object
(http://db.apache.org/torque/apidocs/org/apache/torque/util/LargeSelect.html),
although I have not used it... the page above shows a bit of Velocity
code for getting some records out of a LargeSelect object. 

The LargeSelect object would itself be constructed in a Screen class,
after testing for it's existance in the Session or User object.
