For Liferay 6.1 EE on JBOSS 7.1.1, I am unable to view the various classes to set the log levels within Liferay. I am referring to the option to set the log levels in real-time in the Control Panel -> Server Administration -> Log Levels . This is with a clean install of Liferay. I have been able to reproduce the issue just by using the built-in Hypersonic database as well as the Oracle DB as well.
I've attached a document on how I have been able to get Liferay 6.1 EE to work with JBOSS 7.1.1 to help assist in resolving this issue. This document is in addition to the usual steps to setup Liferay 6.1 with JBOSS 7.0.
