I have been diving into Jaspersoft Studio for a little bit now and I am trying to manipulate the data I get back from a PostgreSQL query. I know that you can use the Expression Editor to manipulate data, but from my experience, it only allows one line of Java. So, Is there a way to use multiple lines of Java (creating variables or even creating methods) to work with the data?
Thanks for any help on this!
Yes, you can use Scriplets
AND custom functions.
JasperReports is designed to allow developers to add their own extensions. JasperReports is very flexible and I've found that I can do almost everything I want to do with it.
