If you use iced_tea java 1.7.0 you can use full 64 bit platform and browser plugin support..

using yum:

yum –enablerepo=development install *\icedtea\*

then

/usr/bin/alternatives –config java

'2' will probably be
/usr/lib/jvm/jre-1.7.0-icedtea.x86_64/bin/java

so:
Enter to keep the current selection[+], or type selection number: 2

then check with:
[incynr8@zundf0lg3 ~]$ java -version
java version "1.7.0"
IcedTea Runtime Environment (build 1.7.0-b21)
IcedTea 64-Bit Server VM (build 1.7.0-b21, mixed mode)

ok now 64 bit real Java is installed it's that stupid plugin you really want for 64 bit moz/firefox and not 32 bit browser and plugins or two browsers or resorting to Konquerer like all the other FAQs out there. And Blackdown is dead, although some dizzy can still run it, if you want 1.4.2Java.....

Web plugin for Firefox 64 bit browser.
# cd /usr/lib64/mozilla/plugins/

# ln -s /usr/lib/jvm/java-1.7.0-icedtea-1.7.0.0.x86_64/jre/lib/amd64/gcjwebplugin.so .



just to show packages:

[incynr8@zundf0lg3 ~]$ yum list java*

now you can run java apps in 64 and have a 64 bit java browser without waiting for a new distribution or dumbing at least your browser down to 32 bit.


After fighting blackdown of FC7 and not wanting 1.42. anyway, while not settling for 32bit on 64, this I found was the cleanest way.
