Sun changed a couple of things recently, so many of the howto’s are outdated – this will work though:

Make sure you remove/disable OpenJDK:

$ rpm -e java-1.6.0-openjdk-plugin

Get the latest Java SE Runtime Environment (JRE) here. Make sure it’s the 64-bit non-RPM version. The RPM might work too, I just didn’t test it. We’ll assume it’s version 1.6.0-12. Execute the following commands to unpack it:

$ umask 022
$ chmod +x jre-6u12-linux-x64.bin
$ ./jre-6u12-linux-x64.bin

Accept the license agreement. The directory jre1.6.0_12 is created. Execute the following commands to move JRE and make a symbolic link to the plugin:

$ mv jre1.6.0_12 /opt
$ cd /usr/lib64/mozilla/plugins
$ ln -s /opt/jre1.6.0_12/lib/amd64/libnpjp2.so .

The new thing here is that they recently renamed the plugin from libjavaplugin_oji.so to libnpjp2.so – that set me off track for a while.

Restart Firefox and type in about:plugins and look for Java – if it’s there, you’re all set.
