I have tried to install Java EE 7 with updatetool to be able to run Java EE Tutorial examples.
But the installation of updatetool fails. I have tried to start updatetool installation from the command line on my elementary os, then I saw the error when installing updatetool.

Error text example 1:
Input/output error: Connection failed for URL http://pkg.oracle.com/javaeesdk/7/native/release/manifest/0/updatetool@2.3.5%2C0-56.2852%3A20111207T211721Z: 503: Service Temporarily Unavailable
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.
