How do I pass a List<int> to a subreport parameter

Hi,

My main report uses a subreport that takes in a List<int> as parameter. I want to be able to pass in a list of Integers from the main report to the subreport. The integer list is the result of a query that needs to be passed to the List<int> parameter of the subreport.

How do I do this using the Jasper Report Engine or iReport?

Any help will be greatly appreciated.
