I have installed JDK 7, but how do I configure settings like security, etc?
On Windows, I can set up JDK 7 from Control Panel -> Java.

Search for "control panel" in the dash. If you're using the Oracle JDK, you'll see the Oracle Java 7 Plugin Control Panel. If you're using OpenJDK, you'll see the Iced Tea Web Control Panel.
To configure certificates in Java control panel for OpenJDK or IcedTea-Web use the command:
javaws -viewer
Search for "java" in dash and it will show java control panel. Images from what it shows when started:
On Ubuntu/mate, you have to configure the IcedTea Web control panel.
System -> Preferences -> IcedTea Web control panel
then you can adjust the security level as shown in the picture below:
Just in case others are using webupd8.org to install the Oracle JDKs, Dash didn't show the Java Control Panel (just the iced tea version).
I ended up having to run the Java Control Panel directly from the command line via /usr/bin/ControlPanel
- their install scripts use update-alternatives
to point there.
dpkg -L openjdk-7-jre
. This command list all files installed by that package.
