Red Hat Enterprise Portal Server
Red Hat has released another Java product: the Red Hat Enterprise Portal Server. The product seems to be closely related to the Redhat Content Management System (formerly the ArsDigita Community System). I say this because the whitepaper was written by former ArsDigita employees (Jim Parsons and Richard Li) and the process for developing a portlet involves writing PDL. The product includes porlets for discussion forum, document management, resource scheduling, tasks, bookmarking, and chat.
Given the anti-Java bias that I have noticed among many Linux devotees (and especially on Slashdot) over the years, I find it interesting and encouraging that all of the "Red Hat Enterprise Applications" (all two of them) are pure Java. Also, the Red Hat Web Application Framework is Java.
