Is it possible to know how pages will be?

Hello,

Is it possible to know how pages will be?

I need to popup custom dialog to user if no pages in report.

I am showing report like that:

Map<String,Date> params = new HashMap<String,Date>();
params.put("dateFrom",this.dateFrom.getDate());
params.put("dateUntil",this.dateUntil.getOneDayFuture());

jasperPrint = JasperFillManager.fillReport(reportName,params,DBConnection.getConnection());

When no pages i got to message boxes "The document have no pages"

Why it message box appears twice?

Is it some way to change message, i want to use other language. I now i can change in source but maybe there are some method?

Thanks a lot

Not exactly, what you can do is print the variable
PAGE_NUMBER in a textfield with evaluation time Report.
The value printed will be the number of pages hold by the variable at the end of the report generation.

you do not need sooo much complexity

if you look at the jasperreports there is a fucnction


isEmpty(), which returns a boolean. you do not need to check page count against a "0", just check the IsEmpty() function.
