Howto install java JDK 7 on CentOS 6 with Java Cryptography Extension (JCE) enabled ready for Tomcat

This installation of java is for people who want to install java and use it with tomcat or any other app that don’t require the java bin to be in the $PATH…


Download the latest JDK 7 release:

If you need to install the JCE, download it: Other Downloads -> Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files. If you don’t know what JCE is, the chance are you won’t need it..

Untar the archive and move it to /opt

# tar -xzvf jdk-7u51-linux-x64.gz
# mv jdk-7u51-linux-x64 /opt/

If you downloaded the JCE, unzip it. We’ll need to overwrite the default file. We’ll backup the file before..

# mv /opt/jdk1.7.0_51/jre/lib/security/local_policy.jar /opt/jdk1.7.0_51/jre/lib/security/local_policy.jar.orig
# mv /opt/jdk1.7.0_51/jre/lib/security/US_export_policy.jar /opt/jdk1.7.0_51/jre/lib/security/US_export_policy.jar.orig
# unzip
# cp UnlimitedJCEPolicy/*.jar /opt/jdk1.7.0_51/jre/lib/security/


And voila!

Hi all! I'm a 27 years old guy from Quebec city, Canada. I've been playing with Linux since 1998 and start to earn my life using Linux and FOSS around 2005. Since then I've earned few certification and courses including CLP10 (Certified Linux Professional from Novell), RHCE (RedHat Certified Engineer) and JBOSS Administration course. I'm a Linux sys admin and I'm working here in Quebec city for a small company who are RedHat Advanced partner since few years. So I'm trying to always keep me updated on new technology and new RedHat product. The best way I've found to do it is to use and contribute to the Fedora Community. So I've joined the community in mid 2009 as a Fedora Ambassadors, I still learning how everything work in a opensource community, but I really liked what I saw at the 2009 FUDCON in Toronto.
