Dear Chrish, thanks for your reply... sry, I guess, I have posted the wrong paramters from my parameter list... this is of course the one I am talking about: ;-) Code: <parameter name="Invoice_Date_From" class="java.util.Date"/> <parameter name="Invoice_Date_To" class="java.util.Date"/> Thanks for the hint (+1).... Anyway, I could also solve my problem using the query inside the jasperreport itself using this format: Code:[code]...BETWEEN to_date($P{S_Invoice_Date_From}, 'dd/MM/yyyy') AND to_date($P{S_Invoice_Date_To}, 'dd/MM/yyyy')... I always tried using the query from inside JasperServer to overwrite the query which was defined in my jasperreport which I was editing with JasperAssistant. As I used different queries for development (to get real data back without entering parameters) I never tried putting my final query in the jasperreport, instead only uploaded to the JasperServer and used it as resource. My issue got solved using query inside jasperreport instead from repository of JasperServer... Thanks, Fab
