好的 - 新玩！框架。我的项目在内置 Play 服务器上运行良好。我正在尝试将相同的项目部署到运行 Tomcat 7 的服务器上，但在 catalina.out 日志中出现以下错误：

我的 web.xml 文件如下所示：

<?xml version="1.0" ?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
        version="2.4">

  <display-name>Play! (MyApp)</display-name>

  <context-param>
    <param-name>play.id</param-name>
    <param-value>war</param-value>
  </context-param>

  <listener>
      <listener-class>play.server.ServletWrapper</listener-class>
  </listener>

  <servlet>
    <servlet-name>play</servlet-name>
    <servlet-class>play.server.ServletWrapper</servlet-class>   
  </servlet>

  <servlet-mapping>
    <servlet-name>play</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

</web-app>

为什么路由在 Play Server 中可以正常工作，但在 Tomcat 中却不行？我需要在 web.xml 文件中声明 conf/routes 文件吗？
