JSF, how to get datatable's first row?

Question

Hi,

I have a datatable where I get its values from a table called Items that is in my database.I want to show first five datas from the Items table but also want to show first row's picture. I get all the pictures from a folder named upload. I keep just the name of the pictures in the database. Could someone please write the code that achieve this?

Thanks so much.
