JasperReports

JasperReports is a Java reporting engine that pulls data from any data source and produces pixel-perfect documents. The same report can be viewed, printed, or exported to HTML, PDF, Excel, OpenOffice, MS Word, and other formats, with charts rendered through JFreeChart.

Reports are written as JRXML templates, compiled to .jasper files, and run through a Java API that embeds the engine directly in an application. Version 7 splits the engine into a core JAR plus optional extension JARs, so a build pulls in only the features it needs.

The library is maintained by Jaspersoft and builds with Maven. Templates are designed in the separate Eclipse-based Jaspersoft Studio, and JasperReports Server and JasperReports IO are commercial products built on the same engine.
