我尝试使用updatetool安装Java EE 7，以便能够运行Java EE教程示例。
但是，updatetool的安装失败。我尝试从基本操作系统上的命令行启动updatetool安装，然后在安装updatetool时看到错误。

错误文字范例1：
输入/输出错误：URL http://pkg.oracle.com/javaeesdk/7/native/release/manifest/0/[email protected]%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。请帮助！
最佳答案
我有同样的看法-这是因为他们的网站是如此之慢。
您显示的输出告诉您该怎么做，增加超时时间。
但是有时只需要再次运行就可以了。
