mappedValue - the filter-specific config value mapped to this filter in the URL rules mappings.

Returns:

true if the request should proceed through the filter normally, false if the request should be processed by this filter's AccessControlFilter.onAccessDenied(ServletRequest, ServletResponse, Object) method instead.

Throws:

Exception - if an error occurs during processing.

onAccessDenied
