Answer 1

Why do you not want to use rich or prime faces or others? Just use primefaces datatable with paginator="true".

If you don't want it, but want to do it the hard way. I suggest you fetch everything from database. Use a datatable and in the getter of that table, you only give back a portion of your array. (index 10 to 20, or index 20 to 40 or...) On top or bottom of your datatable you put some outputlinks. These can set the indexes you want to retrieve.

Hope my explanation is clear.

In case Myfaces Tomahawk is an option for you...

I see it (Myfaces Tomahawk) as a bit different from PrimeFaces/Richfaces cause MyFaces are responsible for the MyFaces JSF Implementation as well (so it could be an excuse for using Myfaces Tomahawk), so you can use the Myfaces JSF implementation + Myfaces Tomahawk

Take a look at the Myfaces Tomahawk datascroller
