Open Flash Chart (ofc) report using iReport

I'm using iReport 3.6. It came as bundled with JasperServer 3.7.

I want to use iReport to develop the flash reports based on OFC (similar to the sample included in 3.7 release). Can anyone help how to get started.

The library "jasperreports-ofc-3.6.2-20091111.130517-2.jar" is already included with 3.7 release, but I'm not sure how to use this in iReport.
