org.apache.jasper.JasperException: 绝对 uri:http://java.sun.com/jsp/jstl/core 无法在 web.xml 或随此应用程序部署的 jar 文件中解析

当我运行我的应用程序时，我得到了这个错误。

这是我的 userForm.jsp

        <tr>

        </tr>
    </table>
</form:form>
<c:if test="${fn:length(userList) > 0}">
    <table cellpadding="5">
        <tr class="even">

            </tr>
        </c:forEach>
    </table>
</c:if>
</body>
</html>

下面是web.xml

【解决方案1】：

这意味着没有安装 JSTL。只需将jstl-1.2.jar 放入/WEB-INF/lib 文件夹并重新启动服务器即可。
