Gantt Chart - JavaScript / JSP / Java / Groovy / Grails

Question

I'm looking to add the ability to create a gantt chart to my web application. Currently my application is Grails based running on Tomcat.

Research around SO seems to indicate that JFreeChart (http://www.jfree.org/jfreechart/) and Google Charts both might provide me with the ability to create charts that I could mold into what I need.

Before I went down that route, though, I wanted to see if there was something that is more specifically tailored to project management type charts.

[Edit: I am open to using JavaScript modules as well]
