Red Hat Application Stack V.2.0 has been tested and certified on Red Hat Enterprise Linux 5 systems. It is not certified for use with earlier versions of Red Hat Enterprise Linux. Please follow the separate instructions for installing Red Hat Enterprise Linux 5 before installing Red Hat Application Stack V.2.0.

Red Hat Application Stack V.2.0 is available for 32- and 64-bit Intel architectures only (i386 and x86_64).

Red Hat Application Stack V.2.0 includes JBoss Enterprise Application Platform 4.2, for running web applications in a standard middleware environment. Note that the JBoss Enterprise Application Platform uses an embedded Tomcat and does not require a stand-alone Tomcat. Before installing and running the JBoss Application Server (the application server component of JBoss Enterprise Application Platform 4.2), you will require a working installation of Java 1.5. Currently Red Hat Application Stack is certified with the Sun JVM 1.5.0 update 12 or later, and the latest BEA JVM available through RHN. Please refer to Chapter 2, Configuring the Java Environment for instructions on configuring the Java environment for JBoss Application Server.

If you intend to use the production config (started by default), you will need atleast 1.5GB of physical memory.
