我也无法在更新工具中看到教程文件.shurik2533给出的下载链接是JavaEE5的教程文件，不是JavaEE6.处理约翰放置的内容，我使用以下命令从 svn 存储库下载了文件:

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
