我也看不到教程文件了更新工具。 shurik2533给出的下载链接是JavaEE5的教程文件，而不是JavaEE6。研究John所说的我使用以下命令从svn存储库下载文件：

I too couldn't see the tutorial files in the update tool. The download link given by shurik2533 are the tutorial files for JavaEE5, not JavaEE6. Working on what John put I downloaded the files from the svn repository using:

$ svn export https://svn.java.net/svn/javaeetutorial~svn JavaEE6tutorial/

仅下载示例：

$ svn export https://svn.java.net/svn/javaeetutorial~svn/branches/javaee-tutorial-6/examples/ JavaEE6TutorialExamples
