How can i install Java Cryptography Extension (JCE)Unlimited Strength Jurisdiction Policy Files in Ubuntu 16.04.
Java Runtime Environment (JRE) is Java’s most basic virtual machine. It’s a required component to run any Java-based application or web applet. Java software allows you to run applications called 'applets' that are written in the Java programming language.
Please tell me also that how can i check that JCE is installed in my system or not?

To see if it has installed, search for the installer. You can try to check in the
var
directory and into cache
.Follow this path:/var/cache/oracle-jdk7-installer/ls.
This will give you all the details about JCE and the Policies.Mercy FlickerMercy Flicker
Installing JCE for JDK7, no longer works from the webupd8 team repository. Follow these instructions for JVM 6 or 7:
- Go to the Oracle Java SE download page.
- Scroll down ... Under 'Additional Resources' section you will find 'Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy File.'
- Download the version that matches your installed JVM, for example, UnlimitedJCEPolicyJDK7.zip.
- Unzip the downloaded zip.
- Copy local_policy.jar and US_export_policy.jar to the $JAVA_HOME/jre/lib/security (Note: these jars will be already there so you have to overwrite them).
