Content management in JSP?

[Ken L]

I am looking for an open-source content management system in JSP. In particular, I want to users to post product reviews. I want to group them into categories. I also want readers post other informal comments on the reviews. Any recommendations?

You can go for Joomla which is the best open source content management system that is widely used recently. It handles all the requirements you want. Let me know if you need more inputs.
