Examples of org.apache.struts.config.ModuleConfig

org.apache.struts.config.ModuleConfig

The collection of static configuration information that describes a Struts-based module. Multiple modules are identified by a prefix at the beginning of the context relative portion of the request URI. If no module 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 module.
