Introduction
1. Overview of This Release
Red Hat Application Stack is a set of software components that have been tested and certified
to work together in an integrated fashion. Red Hat Application Stack is designed for dynamic
web applications for both the LAMP and Java platforms.
2. Installation Prerequisites
• Red Hat Application Stack V.1.2 has been tested and certified on Red Hat Enterprise Linux 4
U5 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 4 before installing Red
Hat Application Stack V.1.2.
• Red Hat Application Stack V.1.2 is available for 32- and 64-bit Intel architectures only (i386
and x86_64).
• Red Hat Application Stack V.1.2 includes JBoss AS 4.2, for running web applications in a
standard middleware environment. Note that JBoss AS uses an embedded Tomcat and does
not require a stand-alone Tomcat. Before installing and running JBoss AS 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 11 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 AS.
• If you intend to use the production config (started by default), you will need atleast 1.5GB of
physical memory.
3. Package-specific Notes
In most cases, Red Hat Application Stack contains more recent versions of packages than
those that are included in Red Hat Enterprise Linux. Installing Red Hat Application Stack may
update/overwrite these packages. Please ensure you review the complete package list before
beginning the installation process.

Configuring the Java Environment
JBoss AS relies on an installed JVM, such as those by Sun, or BEA. Both JVMs are available
from the Red Hat Enterprise Linux (AS/ES) Extras channel.
THIS RELEASE HAS BEEN CERTIFIED WITH THE SUN
AND BEA JVMS.
Currently Red Hat Application Stack is certified with the Sun JVM version 1.5.0
update 11 or later and the latest BEA JVM available through RHN. This may
change in future releases.
With Red Hat Enterprise Linux U5 there are 1.5 versions of the BEA (JRockit), IBM and SUN
SDKs.
We have adopted the jpackage.org style for the packaging of our Java(TM) offerings. This
requires that the jpackage-utils rpm be installed on your system. A JPackage-style JVM must
be installed via up2date (see channel details below) and jpackage-utils will be automatically
brought in as a dependency.
1. Install a supported SDK
1.1. Installing a BEA, IBM or Sun SDK
1. Install a Java SDK from RHN
Java SDKs are provided by the Red Hat Enterprise Linux 4 Extras channel for your Linux
variant and architecture. The channel names are as follows:
rhel-arch-variant-4-extras
where:
arch = i386 or x86_64 variant = as, or es
The java-1.5.0-bea,java-1.5.0-ibm and java-1.5.0-sun SDKs are available from these
channels. Make sure you also install the -devel subpackages.
2. Selecting alternatives for java,javac and java_sdk_1.5.0 (setting java_sdk_1.5.0 is
optional).
This is only needed if you want to use the SysV service script and/or want this installed SDK
to be the default java and javac in the system. This choice can often be overridden by setting
the JAVA_HOME environment variable.
Chapter 2.

The alternatives system allows different versions of Java, from different sources to
co-exist on your system. You should make sure the desired one is selected so that the
service script uses the one you want.
As root, issue the following command:
/usr/sbin/alternatives --config java
and make sure the desired one is selected (marked with a '+'), or select it by entering its
number as prompted.
Make sure you do the same for javac and java_sdk_1.5.0. We recommend that all point to
the same manufacturer and version.
2. Install the jbossas package
2.1. Using up2date / RHN (Preferred Method)
1. up2date your RHEL4 installation and install the JVM as described above.
2. Subscribe to the Red Hat Application Stack child channel:
e.g: rhel-x86_64-as-4-appstk-1 or rhel-i386-as-4-appstk-1
3. Install JBoss AS:
• For the Application Server (which includes an embedded Tomcat), run:
up2date jbossas
Refer also to Chapter 4, Using JBoss AS below.
2.2. Using up2date / DVD
To install using up2date / DVD:
1. up2date your installation and install the JVM as described above.
2. Mount the Red Hat Application Stack V.1.2 DVD.
3. Add the following line to /etc/sysconfig/rhn/sources to use up2date directly on the
RPMs on the disk:
dir RedHat-Application-Stack-V1 path_to_mounted_DVD/RedHat/RPMS
