            <span style="color: purple" th:text="application.name2"></span> ==>
            <span th:text="${application.name2}"></span><br>
        </strong>
    </div><br>
    
    <div th:align="center" style="color: coral">
        <strong>
            <span style="color: purple" th:text="'#session.name'"></span> ==>
            <span th:text="${#session.getAttribute('name')}"></span><br>
    
            <span style="color: purple" th:text="'#serveltContext.name2'"></span> ==>

    <div th:align="center">
