Section 2.4.1 (https://access.redhat.com/documentation/en-US/Red_Hat_JBoss_Web_Server/3/html-single/Installation_Guide/index.html#sect-SELinux_Policies) is incomplete. The section outlines how to create and apply a policy for the tomcat packages, however it doesn't actually update the contexts of the directories so that tomcat abides by the policy. This should be done with a restorecon before the policy actually affects tomcat.
