The original jasperreports-maven-plugin from org.codehaus.mojo was a bit slow. This plugin is 10x faster. I tested it with 52 reports which took 48 seconds with the original plugin and only 4.7 seconds with this plugin.

Since this article was published in late June, we have received a host of excellent comments from readers, hence this update. In particular, thanks to Geertjan Wielenga of the NetBeans IDE team for his valuable input.

The tool for generating reports is an essential component of all enterprise systems and arguably the most valuable one in an application. One such popular, open-source, and Java technology-based tool is JasperReports. Rather than being a standalone product, JasperReports is a framework that you can integrate into your application.

JasperReports ably handles the most common reporting needs—those for relational database applications. The relational database management system (RDBMS) is not the only data storage format available, however. JasperReports' flexibility shines with its customizable datasource API: Whether your data is stored as XML files, in an LDAP repository, accessible through POJOs, or in a proprietary format, JasperReports can handle your reporting needs.
