Java 7更新工具安装失败
我尝试用updatetool安装Java 7，以便能够运行Java教程示例。
但是updatetool的安装失败了。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时看到了错误。

错误文本示例1：
输入/输出错误: URL http://pkg.oracle.com/javaeesdk/7/native/release/manifest/0/updatetool@2.3.5%2C0-56.2852%3A20111207T211721Z：503: Service临时不可用连接失败
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.错误文本示例2：

我也有过同样的经历--因为他们的网站太慢了。
您显示的输出告诉您要做什么，增加超时。
但有时它只需要再运行一次，这在我的情况下是有效的。

3天后，我终于安装了updatetool。
我对所有有同样问题的人的建议是：
在早上、下午、晚上和晚上尝试安装几次。也许一旦你有了成功的尝试：
问题不在我这一边。
