Time for action – installing JRE on Windows
We will install Oracle JRE 1.6. We are assuming that you didn't find any previous Java installation.
Navigate to the Downloads tab at http://www.oracle.com/technetwork/java/javase/downloads/jre6u37-downloads-1859589.html.
Select the installer for Windows 64-bit, that is, jre-6u37-windows-x64.exe, and save it in a convenient folder.
Select the downloaded file and run it as an administrator; press the Yes button when asked from the User Account control.
Go with the default settings and press the Install button.
After it has been downloaded, you should see a window informing you about the success of installation.
What just happened?
We installed JRE on your Windows computer. The first requirement is now fulfilled and you can go over to the Tomcat installation.
