do you use controllers?? normally pages from WEB-INF dir can't be displayed directly by invoking it from browser.
你用控制器吗？？通常 WEB-INF 目录中的页面不能通过从浏览器调用来直接显示。
You should implement controller that will return "next", so it will be resolved to your jsp. Check this tutorialfor more details
您应该实现将返回“next”的控制器，因此它将解析为您的jsp。查看本教程以获取更多详细信息

You can't do that. Here is a quote from the Servlet Specification document that states that:
你不能那样做。这是 Servlet 规范文档中的引述，其中指出：
Except for static resources and JSPs packaged in the METAINF/resources of a JAR file that resides in the WEB-INF/lib directory, no other files contained in the WEB-INF directory may be served directly to a client by the container. However, the contents of the WEB-INF directory are visible to servlet code using the getResource and getResourceAsStream method calls on the ServletContext, and may be exposed using the RequestDispatcher calls.
除了打包在 WEB-INF/lib 目录中的 JAR 文件的 METAINF/resources 中的静态资源和 JSP，容器不能直接向客户端提供 WEB-INF 目录中包含的其他文件。但是，WEB-INF 目录的内容对于使用 ServletContext 上的 getResource 和 getResourceAsStream 方法调用的 servlet 代码是可见的，并且可以使用 RequestDispatcher 调用公开。
