Wildfly in production does not recover properties and SQL script values

Question

I am using a development environment and another production environment, in the development environment using the concept of i18n (Internationalization) is recovered correctly for example the value of label.carro that is Carro, but I put on the production server (which has no client), and it is returned in caption in HTML the value label.carro and not Carro how it should be returned, ie this is not reading the extension file .properties included in the project’s Java Build Path.

The same happens when recovering a file .sql, returns the error NullPointerException when browsing a list of SQL files.

Follow the image of the files in Project Explorer:

Code that recovers files with extension . properties:

import java.util.Locale;
import org.springframework.context.i18n.LocaleContextHolder;
import org.springframework.context.support.ResourceBundleMessageSource;

public class MessageI18n {

    private Locale locale;

    public MessageI18n(Locale locale) {     
        this.locale = locale;
    }

    public MessageI18n() {
         locale = LocaleContextHolder.getLocale();
    }

    public String getMessage(String code) {     
        ResourceBundleMessageSource m = new ResourceBundleMessageSource();
        m.setBasenames("MessageI18N/ValidationMessages","MessageI18N/messages");

        return  m.getMessage(code, null, this.locale);
    }   
}

Code that recovers SQL files, but Nullpointerexception error occurs while entering the repeat loop:

List<String> lst = new ArrayList<String>();

ClassLoader classLoader = getClass().getClassLoader();
File folder = new File(classLoader.getResource("dataBaseVersion").getFile());        

    for (final File fileEntry : folder.listFiles()) {
         // Resto dos códigos
    }

What intrigues me is why you can read the files in development mode, but not in production mode and the settings are the same?
