i read zucker manual and am trying to add parameter to jasper report... i dont know how to add... like if i want user to specify an integer in run time and compare it with a field in jasper and generate accordingly... how to do that? i dont know what they mean by

For your report designs you first have to define your parameters in the “.jrxml”-file
when designing the report. Please be sure to use exactly the same value for the
parameter name in ZuckerReports, as otherwise parameter handling won’t work
where to define in jasper??

Thank You
