JasperReports is an open source Javareporting tool that can write to a variety of targets, such as: screen, a printer, intoPDF, 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.Features of Jaspersoft Report: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.
For users with more sophisticated report management requirements, reports designed for JasperReports can be easily imported into the JasperServer – the interactive report server.
JasperReports Server Community Edition is Jaspersoft’s free, open source reporting and analysis server, based on JasperReports Library, Mondrian, JPivot and Spring. It is licensed under the GPLv2. JasperReports Server Professional Edition is a commercially licensed reporting and analysis server based on JasperReports Server Community Edition. It is “visible” source – code comes with Professional Edition, but it is not free. The Professional Edition extensions beyond the Community Edition include:
- Interactive web based “ad hoc” report development and data exploration (AJAX) against any data source.
- End user query through the browser, based on “data domains” which include data level security. A web based domain designer is provided. JDBC only at this stage.
- In-memory data access and calculation engine to support ad hoc. Includes server management like query governing.
- Dashboards made up of multiple reports, images and external web content can be designed through the browser (AJAX).
- User profile based data level security for OLAP analysis, beyond simple roles.
- Performance tuning and management tools.
- Multi-tenant enabled to support “business intelligence as a service” for SaaS vendors and organizations that share JasperReports Server across customers or departments.
- Complete translations of the JasperReports Server user interface and documentation for English, French, German, Spanish and Japanese (Chinese coming soon)
- Out of the box support to allow JasperReports Server to run in a large variety of application servers and databases for the repository. JasperReports Server Community Edition and Professional Edition can connect to a wide variety of databases for reporting and analysis through JDBC.
