Answer 1

来自javax.servlet.jsp.SkipPageException javadoc ：

以来：

JSP 2.0

因此，这个特殊的例外表明您的webapp的/WEB-INF/lib或更糟糕的是，JRE的/lib或/lib/ext受到特定于servletcontainer的JSP库的污染，例如jsp-api.jar或j2ee.jar ，它们起源于不同的servletcontainer，它只支持较旧的JSP版本。

您应该确保在webapp的/WEB-INF/lib文件夹中或运行时类路径中的其他位置没有特定于servletcontainer的库，这些库只能在目标servletcontainer的类加载中获得优先级（在您的情况下，Tomcat 6.0' s）自己的图书馆。

它们被放置在那里是一个共同的启动者错误，试图“修复”编译错误。 它必须以不同的方式解决。
