我在 web.xml 中使用 2.5 xsd，而我的 Tomcat 是 5.5。

【问题讨论】：

  • 这可能对你有帮助stackoverflow.com/questions/4199596/…
  • class javax.el.E​​LException 在 tomcat 5.5 上不可用，因为它支持 servlet 2.0，您需要的是 servlet 2.1，使用更新的 Tomcat 版本，6.0 应该可以工作。
  • @WundwinBorn 尝试过，但没有解决出现其他错误。现在我正在尝试使用 tomcat 6，请参阅 wat haapens..

【解决方案1】：

你的 Tomcat 已经过时了。 Tomcat 5.5 (Servlet 2.4) 不支持 jsp 表达式语言。请参阅此page 以获取适当的 Tomcat 版本。如果可以，请更新到 Tomcat 7。

    Tomcat 6 解决了这个问题
