First download the current Java 8 SE Development Kit.

Choose the Windows x64 edition and save it to a temporary folder on your server.

Installation

1. Create the folder C:\Program Files\Oracle Java JDK on your server.
2. Start the installer by double-clicking the downloaded .exe file.
3. Click Next. Select Development Tools and set the "Install to..." location to be the folder you created above.
4. Untick Source Code and Public JRE. We don't need these.
5. Click Next to start installing.

Set JDK_HOME Environment variable

Finally we need to set an environment variable to point to our new Java installation:

1. Open the control panel and choose the system applet
2. Click the Advanced tab and the button Environment Variables
3. Click New... at the System Variables
4. Use JDK_HOME as the name of the variable and the path C:\Program Files\Oracle Java JDK as the value.
5. Finish by clicking OK until your are back at the control panel.

Or using the command line:

#!DOS
setx JDK_HOME "C:\Program Files\Oracle Java JDK" /m

1. Open a new command prompt, type set and hit enter
2. Scroll until you see the variable JDK_HOME

Update

It is important to keep Java updated with the latest security patches. To do so simply download the latest installer, Stop your Tomcat-Service and install the new version over the old one. Don't forget to re-start Tomcat after the update.

Silent Installation

If you need to install this product on several servers then a silent installation will make your life easier:

#!DOS
jdk-8u31-windows-x64.exe /s addlocal="ToolsFeature" installdir="C:\Program Files\Oracle Java JDK"
setx JDK_HOME "C:\Program Files\Oracle Java JDK" /m
