JasperReports is the world's most popular open source reporting library.

JasperReports was developed starting in 2001 as a modern, Java-based alternative to Crystal Reports. Developers prefer to embed JasperReports in their applications instead of Crystal Reports or developing their own reports because JasperReports:

• Has clean APIs and open, transparent code.
  Clean APIs are critical for developer productivity. Open and transparent code enables and encourages the development of custom features.
• Is feature-rich.
  You can deliver content-rich and visually compelling reports in a fraction of the time it would take you to program reports on your own.
• Is directly supported by JasperSoft
  and widely supported by community and commercial organizations. JasperSoft offers online and classroom training, comprehensive Ultimate Guide documentation, and a variety of support plans. Third parties also offer their own training, support, and documentation, including newly released books written specifically for Java developers.

Did you know? JasperReports is embedded in JasperServer. JasperServer manages all user interactivity and back-end jobs. JasperReports is the reporting engine that creates pixel-perfect reports for screen and print.
