Has anyone else encountered this problem and does anyone have a
work-around?
Since Scientific Linux 6 and CentOS 6 are so similar, the CentOS wiki
content is applicable:
http://wiki.centos.org/TipsAndTricks/PluginsFor64BitFirefox
I am personally running 64-bit Firefox and the Sun/Oracle Java 17
(CentOS 6.4 x86_64, fully updated this morning):
[lowen@dhcp-pool146 ~]$ java -version
java version "1.7.0_17"
Java(TM) SE Runtime Environment (build 1.7.0_17-b02)
Java HotSpot(TM) 64-Bit Server VM (build 23.7-b01, mixed mode)
[lowen@dhcp-pool146 ~]$ rpm -qa|grep firefox
firefox-17.0.3-1.el6.centos.x86_64
[lowen@dhcp-pool146 ~]$ rpm -qa|grep jre
jre-1.7.0_17-fcs.x86_64

I've attached a jpg of the run on the Oracle java testing page......
(might not make it to the list, so copying directly to Yasha).
The instructions pointed to by the CentOS wiki page at
http://wiki.centos.org/HowTos/JavaRuntimeEnvironment worked here, as far
as I remember, since it has been a few months since I initially got it
working.
Oracle's docs are wrong about 64 bit Firefox and the 64-bit plugin for
applets. I haven't tried Webstart, so don't know if that works or not.
I seem to remember some things being a pain to find (the Java console,
perhaps, to be able to clear the java cache?), but it works for the
applets I need.
I don't know why the Oracle docs still say that the 32-bit plugin and
browser is required; I haven't experienced any issues with the applets
that I have run. And mixing in the 32-bit stuff really complicates things.

Note: CentOS-5 ships with java-1.6.0-openjdk but the x86_64
java-1.6.0-openjdk-plugin package is missing. There is still no native Java
plugin for CentOS-6.

We are using SL 6x x86-64, presumably "the same" as CentOS 6, as both are
direct ports of TUV EL6. It is claimed on the above URL that there is no
native Java plugin for CentOS 6, although your experience with the Oracle
64bit Java package indicates that there is such a plugin.
SL6 ships with icedtea-web on x86_64. This is a java plugin for web browsers.
I can't speak to the Oracle side of things, but there is a native java plugin
for x86_64 in SL.
SL 6.4 BETA has the following:
