JasperReports® - Free Java Reporting Library

The JasperReports Library is the world's most popular open source reporting engine.
It is entirely written in Java and it is able to use data coming from any kind of data source and
produce pixel-perfect documents that can be viewed, printed or exported in a variety of document
formats including HTML, PDF, Excel, OpenOffice, MS Word and other.

Jaspersoft® Studio - open source report designer for the JasperReports Library

The report templates for the JasperReports Library are XML files which can be edited using a powerful,
open source, Eclipse-based report designer called Jaspersoft Studio.
Using Jaspersoft Studio, reports can be built out of any data source and can have their look and feel
formatted for printing or on-screen reading, or can be deployed to a JasperReports Server instance,
JasperReports IO repository or to a custom application using the JasperReports Library implementation
and exported to a wide range of output document formats.
