Relevant releases/architectures: Red Hat JBoss Enterprise Application Platform 5 for RHEL 5 Server - noarch Red Hat JBoss Enterprise Application Platform 5 for RHEL 6 Server - noarch 3. Description: Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss Application Server.
