I've been trying to solve this problem for a while but with no success, here's the details....
1) I've a an arraylist (each element is a bean) in the request
2) On my JSP page I iterate through the collection to display the details, on each line of
the display I add a html:text element (all this is within a html:form -ActionForm)
My issue is when the form is submitted, if the form returns validation errors then I go back
to the same JSP page correctly but I've now lost my arraylist in the request.
How can I get around this (without using SESSION scope or without recreating the arraylist from
the database)?
Hope you can help.

If you refuse to use session, your only option is to create hidden fields on your JSP for the arraylist's values so the values are available in the subsequent request.
To make it easy to keep track of the values, I often will place the data in my ActionForm rather than placing the values into request scope directly.
