In your <forward> element you need to use redirect="true" to decouple
input and output phases. Therefore, you need to stick your ArrayList
into the session. Why not then set ActionForm scope to "session" and
to set ArrayList as nested property of your ActionForm?

This article may help you to understand what is going on (sorry for a
