7.1.3.4. Special variables

The configuration files may contain a special variable reference ${container.name.suffix}. This variable resolves to the name of the current portal container, prefixed by underscore (_). This facilitates reuse of configuration files in cases where portal specific unique names need to be assigned to some resources (For example, JNDI names, Database / DataSource names, JCR repository names).

This variable is only defined when there is a current PortalContainer available - only for PortalContainer scoped services.

A good example for this is HibernateService:
