Не удается создать jdbc resource и connection pool

Пытаюсь соединить базу данных с сервером GlassFish 4.1.1 с помощью настройки пула подключений средствами NetBeans. Делаю все согласно инструкции. Далее, после настройки источника данных и пула подключений перехожу "Серверы" > "GlassFish" > "Ресурсы" > "JDBC" > "Ресурсы и пулы подключения JDBC" и не вижу подключенного ресурса и пула подключений. Соединение с драйвером MySQL (Connector/J driver) установлено:

При выполнении sql запроса выдает исключение: javax.servlet.ServletException: javax.servlet.jsp.JspException: Unable to get connection, DataSource invalid: "java.sql.SQLException: No suitable driver found for jdbc/my_jdbc_resource"
