Thanks for responding :) Please see error from jasperserver.log in the attachment --- basically the error only indicate that the dataset is empty and that it did not find the field it needs in the report. Below is the Report Query in my report: call reporting.sp_balance($P{SiteId}, $P{StartDate}, $P{EndDate}); NOTE: This works in iReport. In addition, instead of passing the parameters into the store procedure I actually passed in values into the store procedure (i.e. call reporting.sp_balance(1, '2007-01-01', '2007-03-31'); ) this works. Which implies that Jasper Server can execute MySQL store procedures; however, did not allow parameters to be pass into a store procedure. Hopefully this information is helpful and can help lead us to a solution. Many thanks in advance your you attention to this issue. Please let me know if you need any additonal information. Ann
