I try to use date parameters (type java.util.Date) with a report. SELECT ... FROM ... WHERE date >= $P{Date1} AND date <= $P{Date2} I have set default value for the 2 parameters like this : new Date(01,01,2001) for Date1 and new Date(31,12,2099) for Date2 but it doesn't work when I launch the report in jasper without parameters. Could you help me.
