org.apache.struts.config.ApplicationConfig

The collection of static configuration information that describes a Struts-based application or sub-application. Multiple sub-applications are identified by a prefix at the beginning of the context relative portion of the request URI. If no application prefix can be matched, the default configuration (with a prefix equal to a zero-length string) is selected, which is elegantly backwards compatible with the previous Struts behavior that only supported one application.
