今天装了个jakarta-tomcat-4.1.24，可是？

legacy

我按照下面的说明文档，做：
(2) Start Up Tomcat 4.0

There are two techniques by which Tomcat 4.0 can be started:

* Via an environment variable:
  - Set an environment variable CATALINA_HOME to the path of the directory
    into which you have installed Tomcat 4.0.
  - Execute the shell command:

      %CATALINA_HOME%\bin\startup             (Windows)

      $CATALINA_HOME/bin/startup.sh           (Unix)

* By modifying your current working directory:
  - Execute the following shell commands:

      cd %CATALINA_HOME%\bin                  (Windows)
      startup                                 (Windows)

      cd $CATALINA_HOME/bin                   (Unix)
      ./startup.sh                            (Unix)

After startup, the default web applications included with Tomcat 4.0 will be
available by browsing:
    http://localhost:8080/

但是当输入http://localhost:8080/时，不能看到期望的页面，不知道是哪里错了，还是还在设置哪些东东？
