    Hi,
    as title says, i finally got it working after pulling my hair for 2 days. So, i figure, this might help to others who want to go 64 all the way down :)

    what i started with:
    [root@orionis amd64]# uname -a
    Linux orionis 2.6.18-92.1.22.el5 #1 SMP Tue Dec 16 11:57:43 EST 2008 x86_64 x86_64 x86_64 GNU/Linux

    firefox 3.0.6 x86_64

    steps:
    1. go to Sun's web site and download the latest version of Java (in my case JRE 6 Update 12) at http://java.sun.com/javase/downloads/index.jsp
    choose 64bit version and download the *.bin version (not the rpm.bin)

    2. I saved jre-6u12-linux-x64.bin file to /opt

    3. /bin/sh jre-6u12-linux-x64.bin will start the install (you have to agree to sun's certificate etc.), the install create directory
    /opt/jre1.6.0_12

    4. run alternatives command:
    [root@orionis /]# alternatives --install /usr/bin/java java /opt/jre1.6.0_12/bin/java 2

    [root@orionis /]# alternatives --config java

    There are 2 programs which provide 'java'.

    Selection Command
    -----------------------------------------------
    *+ 1 /usr/lib/jvm/jre-1.4.2-gcj/bin/java
    2 /opt/jre1.6.0_12/bin/java

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

    - press "2" to make selection for our alternative install

    5. Check to make sure the install was a success

    [root@orionis /]# java -version
    java version "1.6.0_12"
    Java(TM) SE Runtime Environment (build 1.6.0_12-b04)
    Java HotSpot(TM) 64-Bit Server VM (build 11.2-b01, mixed mode)

    6. for some this might be all, but i faced problems with not properly linked plugin, so java still didn't worked in my 64b firefox, so:
    what i did:
    cd /usr/lib64/firefox-3.0.6/
    mkdir plugins
    cd plugins
    ln -s /opt/jre1.6.0_12/lib/amd64/libnpjp2.so libnpjp2.so

    That finally did the job for me.

    You can check out if your browser works with java here:

    Thanks to you all-mighty developers and clever people :)
