    Default LocalDateTime.isAfter() method in JSP - NullPointerException

    Recently, I have had trouble comparing LocalDateTime instances using the predefined method isAfter().

    I have tried the following in Eclipse and it works fine:

    stock.getReserveDate().isAfter(LocalDateTime.now())

    where stock is a JPA Entity with a LocalDateTime field that has a getter called getReserveDate().

    Executing the following code in JSP(which I believe is identical to the line above) gives me a NullPointerException.

    <c:when test="${compStock.getReserveDate().isAfter(LocalDateTime.now())}">
        <p>Stock is reserved!</p>
    </c:when>


    After debugging, I've managed to find out that the LocalDateTime.now() part of my code is considered null by JSP / JSTL but I have no idea why. This code works perfectly when ran in Eclipse but fails in a JSP.
