Separate PDFs for each report group element

[matthew.kellar]

Hello there!

Ok, so I've got a tricky one. I've got a report that has multiple subreports. Each one of those subreports contains a report group that puts each data element onto a new page, then the master report compiles all of those into a single PDF. I need a way to instead generate a separate PDF file for each record, while still only making 1 rest call. I also need to be able to dynamically change the PDF names to match the data element value. Any ideas?

https://stackoverflow.com/questions/12688778/increase-tomcat-memory-settingsJasperReports only output 1 pdf per report. You'll have to create your own program that uses JasperReports library to do that.

I've done what you've asked before several times so I'm definitely sure that it's possible if you build your own program.

@hozawa, thank you for the response, but it looks like that link is unrelated, do you have another link?

Below is the code that i wrote in java for the same purpose... try to salvage some code and write your own scriptlet in jasper reports.
