HTML frame issues and dilemma

Background: We need to use a frame in the front end of our application.

Problem:

1. The tag frameset and frame doesn't work. Weird thing is if we try this in a plain html file, it works but when we do it in a jsp file, it doesn't.

2. We tried using iframe instead but with this, we cannot remove the scrollbars at the side.

Can anyone help? are there better alternatives?

by the way, the browser requirements in our application: the minimum requirement is IE6 (yeah i know we no longer shouldn't be using this because its old and phased out but that is what our client wants)

That is all. Thanks :-)
