Java can be downloaded directly from Sun’s Website

Where can I download the Sun Java MSI to deploy to my network?

Firstly you need to download the latest Sun Java Offline version to your local computer e.g. C:\Java

Run the file you have downloaded and wait for setup to initialise. You’ll then see a Java Setup Welcome screen. Do not click the Accept button, but navigate to:

C:\Documents and Settings\%Username%\Application Data\Sun\Java\ or

C:\Users\%Username%\Appdata\Sun\Java 

Copy the MSI and cab file to a new directory, then cancel Java Setup. Providing these two files are in the same directory, you can deploy Java to your network.
