Tutorial for Externalizing strings on server side of Questions on the Natural Language Classifier Application

To externalize strings on server side of the application we need to prepare our translation according to this file:
./questions-with-classifier-ega-war/src/main/resources/messages/messages.properties

Like: AQWQAC14003E_no_available_classifiers = Your translation

Save this file with different name: ex. messages_es.properties
