Further to my post about multiple webroots and domains in a single instance, to have multiple domains point to a single webroot (.war) you need to do the following:

> JBoss:

1. Edit your jboss-web.xml file (jboss/server/default/deploy/cf_website1.war/WEB-INF/jboss-web.xml) and make sure you have a virtual-host node.

<jboss-web>
        <context-root>/</context-root>
        <virtual-host>cf_website1</virtual-host>

</jboss-web>

2. Edit your server.xml file (jboss/server/default/deploy/jbossweb.sar/server.xml) and make sure you have a host defined. If you don't, add one, if you do, add each url you want to use in using the <Alias> node.

<Host name="cf_website1">
        <Valve className="org.apache.catalina.valves.AccessLogValve"
                prefix="cf_website1_access_log." suffix=".log"
                pattern="%t %H %m %U %s %q %b %D %I %h"   directory="${jboss.server.log.dir}"
        resolveHosts="false" />
        <Alias>website1.mysites.com</Alias>
        <Alias>www.website1.com</Alias>
        <Alias>61.235.111.22</Alias>
</Host>

> Apache:

1. Add each url you want to use in using the ServerAlias parameter.

<VirtualHost *:80 >

    ServerName website1.mysites.com
    ServerAlias www.website1.com
    ServerAlias 61.235.111.22

    ProxyPass /CFIDE                http://127.0.0.1:8090/CFIDE
    ProxyPassReverse /CFIDE         http://127.0.0.1:8090/CFIDE
 
    ProxyPass /website1              http://127.0.0.1:8090/website1/
    ProxyPassReverse /website1       http://127.0.0.1:8090/website1/

    ProxyPass /                     http://127.0.0.1:8090/website1/
    ProxyPassReverse /              http://127.0.0.1:8090/website1/

    ProxyPreserveHost on

</VirtualHost>

> Misc:

1. You will need to restart both Apache and JBoss for these changes to take effect.
