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.
