Yes, I understand. But who needs that ?! One collection for a report ? In
every application I have complex reports with SQL queries on the databse,
and only I need to pass parameters.
O.K. Anyway, what I need to change in order that JR result accept Connection
object ? Can I just say: Connection con = stack.finValue("connection"); and
then to call JR fillReport(...) with that object in JR result ?
