JasperReports Library is a Java reporting engine for generating structured documents from application data. It is designed for software developers who need to produce reports, invoices, statements and other business documents within their own applications.
The library separates the description of a report from the data used to populate it. Report layouts are defined using JRXML templates, which can contain text, images, charts, tables and other elements. Applications supply the relevant information and use the reporting engine to generate the finished document.
JasperReports can be embedded in Java applications or used as part of a larger reporting environment. Jaspersoft Studio provides a graphical report designer, allowing layouts to be created without editing every aspect of the underlying XML manually.
This is free and open source software.
Key Features

- Export documents to PDF, HTML, Excel, Word, CSV, XML and other supported formats.
- Generate reports containing Unicode text and internationalised resources.
