Scriptlets in reports when launching from Java

[amongalen]

Hello

I've got a Java application that uses JasperReports Library to compile and fill reports. In some of my reports I got some scriptlets I'd like to call. Using them in JasperSoft Studio is rather straightforward.

When I try to fill a report containing scriptlets from Java app I get following error:

net.sf.jasperreports.engine.JRException: Error loading scriptlet class ...

Which is to be expected, because I didn't specify anywhere where the class is located. I've tried to add the scriptlet jar as a library to that Java project and it kinda works.

The problem is I'd like to be able to add scriptlet jars at runtime, e.g: load all that are in the xyz folder. In my project I'll have hundreds of reports, many of them will have to use scriptlets. Adding them as a library everytime someone creates a reports isn't an option.

Is there some way to load scriptlet class/jar from Java at runtime?
