Procedure 8.1. Install Native Components from RPM

  1. Subscribe to the JBOSS EAP5 RHN channel

    1. Using a web browser, navigate to http://access.redhat.com and log in with your credentials.
    2. View the list of all systems, and find the system on which you have installed the Enterprise Platform. Click to view its subscriptions.
    3. Add the JBoss Application Platform or JBoss EWP channel appropriate to your version of Red Hat Enterprise Linux.

  2. Install the mod_cluster-jbossas package

    Log into the application server's host system as the root user. issue the command yum install mod_cluster-jbossas

  3. Alternative: Install the mod_jk-ap20 package

    Only follow this step if you need to use mod_jk instead of mod_cluster. Log into the application server's host system as the root user. s the root user, issue the command yum install mod_jk-ap20.

Procedure 8.2. Install Native Components from ZIP Archives

This procedure installs the Native Components for JBoss Enterprise Web Platform.
Prerequisite:
Install JBoss Enterprise Web Platform via ZIP, RPM, or the Graphical installer before carrying out this procedure. See Section 4.3, “Installation Methods” for more details.

  1. Download software

    Refer to Appendix B, The Red Hat Customer Portal for file download instructions.
    To install Native Components, choose the Native Components download that corresponds to your operating system and the architecture of your Java Virtual Machine.

  2. Unzip components

    Extract the native directory from the zip file into the jboss-ewp-5.x directory, so that the native directory is at the same directory level as the jboss-as-web directory.
    Result:
    The Native Components are installed.

  3. Verify installation

    During server startup the server will report the presence of the Native libraries: 
    12:12:29,826 INFO [ServerInfo] VM arguments: -Dprogram.name=run.sh -Xms1303m -Xmx1303m
         -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true -Dsun.rmi.dgc.client.gcInterval=3600000
         -Dsun.rmi.dgc.server.gcInterval=3600000 -Dsun.lang.ClassLoader.allowArraySyntax=true
         -Djava.protocol.handler.pkgs=org.jboss.handlers.stub -Djava.net.preferIPv4Stack=true
         -Djava.library.path=/home/ewpuser/jboss-ewp-5.1/native/lib64
         -Djava.endorsed.dirs=/home/ewpuser/jboss-ewp-5.1/jboss-as/lib/endorsed
    The option -Djava.library.path=/home/ewpuser/jboss-ewp-5.1/native/lib64 shows that the server is detecting and loading the Native libraries.
