This powerful reporting library aims to simplify producing reports using iText. The most demanding and coding intensive tasks when producing reports with iText are how to get from data to report elements, how to style those blocks and how to evaluate (debug) the resulting report layout. Exactly those three tasks are simplified by this library: xml configuration and/or annotations to transform existing Java data objects into report block, provide styling information (css like, syntax independent) seperate from code, a firebug like debug mode to help evaluate your report.

There is a newer version: 9.2
