无法访问应用程序在播放框架

您好我安装了新版本的播放框架2.0。现在我试图从教程连接到示例应用程序，但似乎没有工作。这里是我做的：无法访问应用程序在播放框架

创建 “todolist的” 应用程序：

play new todolist

 play! 2.0, http://www.playframework.org
 The new application will be created in /home/evermean/Code/playWorkspace/todolist
 What is the application name?

 >todolist
 Which template do you want to use for this new application?
 1 - Create a simple Scala application
 2 - Create a simple Java application
 3 - Create an empty project
 > 2

OK, application todolist is created. Have fun!

执行播放命令：

 $ cd todolist 
 $ play

执行run命令：

[todolist] $ run

 Now I try to connect to the site http://localhost:9000
 I get the following output:
