Examples of org.mojavemvc.exception.ConfigurationException

org.mojavemvc.exception.ConfigurationException

Signals that the application is using the framework's annotations incorrectly. This exception will typically be thrown during the initialization of the front controller. It will prevent the application from starting up, as it cannot do so correctly given the state of the annotation-defined configuration.
