7

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.

  • Maybe it have some configuration files, you can find them by dpkg -L openjdk-7-jre. This command list all files installed by that package. – shgnInc Apr 10 '14 at 5:18

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.

    If you use Oracle Java you can run the control panel from jcontrol under the installation path, if you prefer to use a terminal – webbertiger Jun 11 '15 at 18:56

To configure certificates in Java control panel for OpenJDK or IcedTea-Web use the command:

javaws -viewer
  • Also works for Oracle Java – Farhan.K Jan 29 '18 at 16:37

  • 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 – taymindis Woon Apr 10 '14 at 15:17

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.
