DynamicReports is an open source Java reporting library based on JasperReports. It allows to create dynamic report designs and it doesn't need a visual report designer. You can very quickly create reports and produce documents that can be displayed, printed or exported into many popular formats such as PDF, Excel, Word and others.

The newest version!
