question: private String resolveEndpoint ( IBindingSet bs ) { String endpointStr = resolveAsString ( endpoint , bs ) ; if ( endpointStr == null || endpointStr . isEmpty ( ) ) { endpointStr = defaults . getDefaultEndpoint ( ) ; } if ( endpointStr != null && ! endpointStr . isEmpty ( ) ) { return endpointStr ; } else { throw new FulltextSearchException ( FulltextSearchException . NO_ENDPOINT_SPECIFIED ) ; } }
