JasperSoft - iReport plugin:

Jaspersoft is a commercial provider of open-source BI solutions and a longtime member of the NetBeans community. The San Francisco-based company announced last week the full-production availability of the iReport plug-in. iReport has been certified both for NetBeans 6.0 and 6.1, and it's also in the process of getting that certification for the upcoming NetBeans 6.5, which was just released in beta. "We'll be ready when it goes GA," Halsey told this site. "It's fully supported now."
