[Building Sakai] JForum ClassCastException

[Murthy Tanniru]

Hi Cutis,

The latest is JForum 2.9.11. Check the release notes at 
http://etudes.org/release/discussion/install-guide.htm . This version 
should work with Sakai 2.9.1. It works only with MySQL. Get the etudes 
util as per the installation notes. Latest etudes util version may work 
but to be tested.
