Question

我尝试使用updatetool安装Java EE 7，以便能够运行Java EE Tutorial示例。

但是updatetool的安装失败了。我试图从我的基本操作系统的命令行启动updatetool安装，然后我在安装updatetool时看到了错误。

输入/输出错误：网址http://pkg.oracle.com/javaeesdk/7/native/release/manifest/0/updatetool@2.3.5%2C0-56.2852%3A20111207T211721Z的连接失败：503：服务暂时不可用

Could not download application packages. This could be because:
  - a proxy server is needed to access the internet. Please ensure that
    the system proxy server settings are correct, or set the 'http_proxy'
    environment variable to the full URL of the proxy server.
  - the package server or network connection is slow.
    If you are getting time out errors you can try setting the
    PKG_CLIENT_CONNECT_TIMEOUT and PKG_CLIENT_READ_TIMEOUT
    environment variables and try again. For example to increase
    the timeouts to 300 seconds set them to 300
  - the package server is down or otherwise inaccessible or it is
    generating invalid data. Please contact the provider of the package
    server.

我不使用任何代理服务器。求救！

Answer 1

我也一样 - 这是因为他们的网站速度令人难以置信。

您显示的输出告诉您该怎么做，增加超时。

但有时它只需要再次运行，这在我的情况下有用。

Answer 2

您可以从Oracle Java EE 7 SDK download page下载该教程。

只需下载最新的Java EE 7 SDK，然后解压缩即可。该教程位于glassfish4 / docs文件夹中。

Answer 3

我已经设法在3天后最终安装了updatetool。

对于遇到同样问题的每个人，我的建议是：

早上，下午，晚上和晚上多次尝试安装。也许一旦你有成功的尝试：）

问题不在我身边。
