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.

The name of the control panel is different depending on whether you are using the Oracle JDK or OpenJDK.
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.

1If you use Oracle Java you can run the control panel from jcontrol under the installation path, if you prefer to use a terminal Jun 11, 2015 at 18:56
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:

No,I couldn't find out this in dash command, what Java Packages I had installed are:- icedtea-7-jre-jamvm:amd64, openjdk-7-jdk:amd64, openjdk-7-jre:amd64, openjdk-7-jre-headless:amd64 Apr 10, 2014 at 15:17
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.
