Is it possible to know how pages will be?

[prancius]

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.

I need to know how many pages before showing a report. If pages are 0 so i am popup some message to user and do not showing report.

 

Anyway why its popup two messages ???

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.
