Installed Oracle Java with the webupd8 ppa and need to tweak some policy settings (access to clipboard specifically)
webUpd8 plug: http://www.webupd8.org/2011/09/how-to-install-oracle-java-7-jdk-in.html
(these guys have done alot for the Ubuntu community)
Previously it was under /etc/java-6-oracle
Google doesn't have any answers on this one — any ideas?
From a terminal, Confirm if the package is installed using.
sudo dpkg -l|grep -i sun-java6-jdk
List all the files installed by the package using
sudo dpkg -L sun-java6-jdk
The listing of all files will help you to locate where directories/files installed by Ubuntu.
Install Oracle/Sun Java. See How can I install Sun/Oracle's proprietary Java JDK 6/7/8 or JRE? (and others) for details.
In a terminal session, run : sudo update-alternatives --config java
You will get a list that looks something like this:
As per the instructions at the prompt, enter the number corresponding to the version you want to be your system default Java implementation.
Once you've done that, unless there are configuration settings directing otherwise for particular applications (quite common), the Java version you've chosen will be your global system default.
I would definitely not recommend removing entirely the OpenJDK. There are any number of modules and applications that may be expecting OpenJDK to be there and are configured to use it - it's the default Java that comes with Ubuntu. Removing it may cause some serious problems. Leave it in place for those modules that expect it, because it is the default. You have set the default to what you want, and you can control the applications you are using to use that setting (in fact you can do it on an application by application basis without changing the system default at all) - but not everything is under your control, at least not without some serious expertise and mucking around.

The keystore is : jre/lib/security/cacerts . You can list its contents by:
To find JAVA_HOME, issue this command:
And then run that program.
But, it sound to me like you dont need to alter the keystore. What you need to do is edit the .policy file. It's easy to find at:
Of course, if you still cant find it then it is easy to derive with this command:
