JasperReports is an open source Java reporting tool that can write to a variety of targets, such as: screen, a printer, into PDF, HTML, Microsoft Excel, RTF, ODT, Comma-separated values or XML files.
It can be used in Java-enabled applications, including Java EE or web applications, to generate dynamic content. It reads its instructions from an XML or .jasper file.
JasperReports is part of the Lisog open source stack initiative.

Features
JasperReports is an open source reporting library that can be embedded into any Java application. Features include:
- Scriptlets may accompany the report definition, which the report definition can invoke at any point to perform additional processing. The scriptlet is built using Java, and has many hooks that can be invoked before or after stages of the report generation, such as Report, Page, Column or Group.
- Sub-reports
For users with more sophisticated report management requirements, reports designed for JasperReports can be easily imported into the JasperServer - the interactive report server.

Jaspersoft
Teodor Danciu began work on JasperReports in June 2001, the sf.net project was registered in September 2001 and JasperReports 0.1.5 was released on November 3, 2001.
JasperReports Version 1.0 was released on July 21, 2005.
The code was originally licensed under a copyleft JasperReports License and later moved to LGPL.
Jaspersoft was originally called Panscopic, and was founded by Al Campa, CEO, and Raj Bhargava, VP of Products in 2001. Panscopic raised $23M from Doll Capital, Discovery Ventures, Morgenthaler Ventures, and Partech. In 2004 Panscopic teamed up with Teodor Danciu, acquired the intellectual property of JasperReports, and changed the name of the company to Jaspersoft. Brian Gentile became CEO in 2007.
Jaspersoft provides commercial software around the JasperReports product, and negotiate contracts with software developers that wish to embed the JasperReports engine into a closed source product.
Jaspersoft's main related product is JasperReports Server, a Java EE web application that provides advanced report server capabilities such as report scheduling and permissions. It is available under an open source license for use in conjunction with open source infrastructure such as MySQL and JBoss, or a commercial license for enterprise deployments involving commercial databases and application servers.
Jaspersoft is a gold partner with MySQL, and JasperReports was included in the PostgreSQL distribution Bizgres version 0.7.
On April 28, 2014, TIBCO announced it had acquired Jaspersoft for approximately $185 million.
JRXML
JasperReports reports are defined in an XML file format, called JRXML, which can be hand-coded, generated, or designed using a tool. The file format is defined by a Document Type Definition (DTD) or XML schema for newer versions, providing limited interoperability. JRXML files have the filename extension .jrxml.
A .jasper file is a compiled version of a .jrxml file. iReport does the compilation on the fly, but the compilation can also get achieved at runtime using the JasperCompileManager class.
IDE integration
Several Java IDEs, such as NetBeans, Eclipse and IBM Websphere Studio Application Developer provide instructions for users wishing to integrate JasperReports into a project.
