Rename $JBOSS_HOME/server/default/deploy/ext.ear/portal-web-complete.war to portal-web-alpha.war.

Copy $JBOSS_HOME/server/default/deploy/ext.ear/portal-web-alpha.war to portal-web-beta.war.

Edit $JBOSS_HOME/server/default/deploy/ext.ear/portal-web-alpha.war/WEB-INF/web.xml and change the value of the company id to alpha.com.

<context-param>
    <param-name>company_id</param-name>
    <param-value>alpha.com</param-value>
</context-param>

On startup, the portal will create the necessary database entries and create a default user account with [email protected] as the login and test as the password.

Repeat this step for $JBOSS_HOME/server/default/deploy/ext.ear/portal-web-beta.war/WEB-INF/web.xml but replace alpha.com with beta.com.

Edit $JBOSS_HOME/server/default/deploy/ext.ear/portal-web-alpha.war/WEB-INF/jboss-web.xml to add the context root and virtual host.

<jboss-web>
    <security-domain>java:/jaas/PortalRealm</security-domain>
    <context-root>/</context-root>
    <virtual-host>www.alpha.com</virtual-host>
    ...
</jboss-web>

Repeat this step for /server/default/deploy/ext.ear/portal-web-beta.war/WEB-INF/jboss-web.xml but replace alpha.com with beta.com.

Edit $JBOSS_HOME/server/default/deploy/ext.ear/META-INF/application.xml.

Remove the old reference to portal-web-complete.war and add the references to portal-web-alpha.war and portal-web-beta.war.

<module>
    <web>
        <web-uri>portal-web-alpha.war</web-uri>
        <context-root>/</context-root>
    </web>
</module>
<module>

        <web-uri>portal-web-beta.war</web-uri>
        <context-root>/</context-root>
    </web>
</module>

Edit $JBOSS_HOME/server/default/deploy/jbossweb-tomcat50.sar/server.xml to add the alpha and beta hosts.

<Engine name="jboss.web" defaultHost="www.alpha.com">
    ...
    <Host name="www.alpha.com" ...
        ...
        <DefaultContext cookies="true" crossContext="true" override="true" />
    </Host>
    <Host name="www.beta.com" ...
        ...
        <DefaultContext cookies="true" crossContext="true" override="true" />
    </Host>
</Engine>
