Charting Portlet using JSR-286

A while ago I had written an SDN article on how to generate charts dynamically in portlets. Following up on that, I have created a portlet that uses the JSR-286 feature of serve resources, to dynamically generate charts by reading its data from a JDBC compliant database. The essential feature of this portlet is that the image is generated dynamically and served via a serve resource call and isn't stored in any temporary location. The portlet can be run under any portlet container that supports JSR-286 specification. It has been tested on OpenPortal Portlet Container which supports the draft 19 of the JSR_286 specification. You can download the portlet war file from here.
