Is there a way to set the maximum number of pages?

Is there a way to set the maximum number of pages and warn the user when querying a report greater than a certain amount of pages in JasperReports?

Thank You,

Sean

Hi,

 

Yes, this is what we now call report governors.

Basically, a governor is a global scriplet. They were introduced in JR 3.1.4.

Check this config properties you could use:

http://jasperreports.sourceforge.net/config.reference.html#net.sf.jasperreports.governor.max.pages

http://jasperreports.sourceforge.net/config.reference.html#net.sf.jasperreports.governor.max.pages.enabled

 

I hope this helps.

Teodor
