This JDK (JRE) version is still in development, but for me it works and is very stable. If You have any problems, go to this forum.
1.Download the latest JDK (JRE) for 64bit systems from this site. This is the 3rd build of JDK (JRE) SE 6u12 (I always download the binary .rpm file; if You prefer, You can download the binary self-extracting file, and find the install instructions here)
2.Now open terminal, and (as root) go to the destination, were You store the downloaded files:
su root
cd <download folder)
3.When You’re there, You have to set the executable permissions:
chmod a+x <file>.bin
4.And then run the binary:
./<file>.bin
5.The installation will start. You’ll be prompt to accept the license agreement.
6.The last thing to do is to set up a link to You’re browser (I have only tried this plugin on Firefox 3.04, but it should work for Opera as well):
ln -s /usr/java/jdk1.6.0_12/jre/lib/amd64/libnpjp2.so /usr/lib64/browser-plugins/libnpjp2.so
And You are done.
