What claims to be the 2.2 Server install/upgrade documentation appears to be a copy'n'paste of the 2.1 documentation: 2.1: http://www.redhat.com/docs/en-US/JBoss_ON/html/Installation_Guide/Installation_Guide-Server_Upgrade-Unzip_the_new_version_of_the_JON_Server.html 2.2: http://www.redhat.com/docs/en-US/JBoss_ON/2.2/html/Installation_Guide/Installation_Guide-Server_Upgrade-Unzip_the_new_version_of_the_JON_Server.html (Notice it refers to JON 2.0.1)
doc fixed
