Interesting article on Liferay and Alfresco integration

I’ve been tracking the efforts of Liferay and working with Alfresco for a couple of years now and this article at Rivet Logic Blogs by Alaaeldin El-Nattar caught my eye. Discussed are the integration capabilities of the two products and the JSR-168/286 specification. Check it out!
