    Just to share how I did the install on Scientific Linux. (Yes, I need it for stock charts so can't do without unfortunately).

    Install sun jre SL6 (64bit version)

    Download the bin file jre-6u24-linux-x64.bin from https://cds.sun.com/is-bin/INTERSHO...ProductRef=jre-6u24-oth-JPR@CDS-CDS_Developer Save to Desktop.

    AS ROOT

    1. mv /home/yourusername/Desktop/jre-6u24-linux-x64.bin /opt/
    2. cd /opt/
    3. chmod +x jre-6u24-linux-x64.bin
    4. ./jre-6u24-linux-x64.bin (the./ means you will run the install script)
    5. cd /usr/sbin
    6. alternatives --install /usr/bin/java java /opt/jre1.6.0_24/bin/java 2
    7. cd /
    8. usr/sbin/alternatives --config java

    After completion of step 8. you should see something like this:-

    There is 1 program that provides 'java'.

    Selection Command
    -----------------------------------------------
    *+ 1 /opt/jre1.6.0_24/bin/java

    Enter to keep the current selection[+], or type selection number:
    [root@localhost /]#

    9. usr/sbin/alternatives --display java
    Tests to see all OK. You should get something like this:-

    java - status is manual.
    link currently points to /opt/jre1.6.0_24/bin/java
    /opt/jre1.6.0_24/bin/java - priority 2
    Current `best' version is /opt/jre1.6.0_24/bin/java.

    Now the browser links.

    Opera.

    Tools>Preferences>Advanced>Content>Plug-in Options>Change Path>Add
    Browse to /opt/jre1.6.0_24/lib/amd64
    OK>OK>OK

    Firefox.

    I made a soft link ..

    ln -s /opt/jre1.6.0_24/lib/amd64/libnpjp2.so /usr/lib64/mozilla/plugins/

    Check about:plugins

    Test the browser(s) http://www.java.com/en/download/help/testvm.xml

    [I also did this although I am not sure whether needed. I have never needed it.
    (Also as root)

    gedit /etc/profile.d/java.sh

    Enter the following environment variables:

    export J2RE_HOME=/opt/jre1.6.0_24
    export PATH=$J2RE_HOME/bin:$PATH

    Add an empty line at the end of the file.]
