DynamicJasper (DJ) is an open source free library that hides the complexity of Jasper Reports, it helps developers to save time when designing simple/medium complexity reports generating the layout of the report elements automatically.
DJ creates reports dynamically, defining at runtime the columns, column width (auto width), groups, variables, fonts, charts, crosstabs, sub reports (that can also be dynamic), page size and everything else that you can define at design time (see features).
DJ keeps full compatibility with Jasper Reports since it's a tool that helps creating reports in a programmatic friendly way, taking care of the report design for you.
Classic .jrxml files can be used as templates while the content and layout of the report elements are handled by the DJ API.
Version 3.0.0 introduces breaking changes
Dj currently supports JasperReport 3.0 to 3.5.1.
Version 3.5.2+ is NOT yet supported
Since DJ 3.0.9 Struts 2 integration classes will be in a separated jar (because they need java 1.5 to compile)
The DJ Playground is an example web application intended to show some of the API capabilities and its full potential. See it working online!!! or download it.
Crosstabs are double entry tables where columns and rows depends on the data. This great feature introduced by JasperReports is easily available through DynamicJasper.
With DynamicJasper it is really easy to get reports of different nature concatenated in a single one
