I have a Maven Web application in NetBeans running on GlassFish 4.1.1, and a basic CRUD class has been created to receive and return in JSON format, but when it is to be returned a List<String> the server has an error :
Serious: MessageBodyWriter not found for media type = text / plain, type = class java.util.ArrayList, genericType = java.util.List.
Below is GlassFish server logging
