java - 解决 Tomcat 8.0.15 和 java 8 上的 tomcat proprietaryEvaluate 异常

Question

我必须从 Java 7 & tomcat 7.0.57 的执行环境切换到 java 8 & tomcat 8.0.15。为此，我正在测试一个我知道在 J7/TOMCAT7 上运行良好的 Web 应用程序。我正在使用配置为使用 java 8 的 maven，并且部署进展顺利。同时，当我尝试加载我的主页时，我在执行期间遇到了这个异常:

An error occurred at line: 427 in the jsp file: /index.jsp The method proprietaryEvaluate(String, Class, PageContext, ProtectedFunctionMapper, boolean) in the type PageContextImpl is not applicable for the arguments (String, Class, PageContext, null)

完整的堆栈跟踪:

请注意，我没有使用任何框架，如 Struts 或 Spring。

有什么办法可以解决这个异常？

Answer 1

我在升级时遇到了同样的问题，问题是我部署的 WAR 包含了 jasper jar，这是不应该的。我删除了它，因为 Tomcat 提供了它自己的(并且 TC8 中的方法签名与 TC7 中的版本不同)并且它现在可以工作。
