I have a website developed using Java EE and the Seam Framework. We are currently investigating the possibilities to add a CMS in the project.

Reading this [article](http://www.gerrykirk.net/10-reasons-to-choose-plone-cms-for-your-web-site/) I got the impression that [Plone](http://plone.org/) is able to deliver content using Java, but I was not able to find any documentation or case studies yet. 

Does anyone here have experience with this match? Possibly with the Seam framework in the mix?
