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 a CRUD will be returned List<String> the server shows an error:

Grave: Messagebodywriter not found for media type=text/Plain, type=class java.util.Arraylist, genericType=java.util.List.

Below goes Glassfish server log

The other methods work, only this one that should return an Arraylist does not work. Below goes the class method that returns the Arraylist:

@GET
@Produces(MediaType.TEXT_PLAIN)
@Path("/")
public List<String> listChamados() {
    List<String> lista = new ArrayList<String>();
    try {

        lista.add("Verificar a diferença de preço entre a parcela e a fatura.");
        lista.add("Não esqueça de buscar todos os erros.");
    } catch (Exception ex) {
        lista.add(ex.getMessage());
    }
    return  lista;
}

Try to change the MediaType of your @Produces.

From what I understand he is not able to parse his List for Plain Text, try to use the MediaType correct for json.

MediaType.APPLICATION_JSON or MediaType.APPLICATION_JSON_TYPE

I’ve tried this before, I’ve changed the MediaType before to MediaType.APPLICATION_JSON and the same error persists.

Trade for MediaType json and put the error stack in the question.
