In keeping with the customs of this list, I am appending the current
situation on the bottom of this list response.

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:

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:

Summary : Additional Java components for OpenJDK
Description :
The IcedTea-Web project provides a Java web browser plugin, an
implementation
of Java Web Start (originally based on the Netx project) and a settings
tool to
manage deployment settings for the aforementioned plugin and Web Start
implementations.

Afrer various experiments (attempts) to get things working, we settled
upon the following:
1. At least one application we needed required Oracle ("Sun") Java and
had not been tested with the open systems distro java and in fact
rejected such a java under direct tests. Because another application
required javac for certain capabilities, we downloaded the current
installable executables of jdk in compressed tar format for both IA-32
and X86-64.
2. We downloaded the current production Mozilla Firefox x86-64 at a
compressed tar file, not the SL6 distro version. The decision to use
current production Firefox over the distro "stable enterprise" version
was made after significant internal discussion evaluating the issue. I
can outline the reasoning behind our conclusion under a separate list
thread if there is interest.
3. We also downloaded the current production Google Chrome x86-64.
4. With all of these under SL6x X86-64, we were able to get java and
javascript operational within both Chrome and Firefox using the x86-64
Oracle installation files for executables.
5. Within /etc/alternatives, we had to make the jre and java point to
those from the Oracle distribution, not the SL6x distro. In principle,
an appropriate shell environment for execution of non-SL6x targeted
applications (e.g., not from SL6x, elrepo, etc.) should have avoided the
necessity of this step, but simply modifying /etc/alternatives was
faster and simpler.
However, not all of the plugins that we probably want seem to be
available in x86-64.
Here is a list of what I have under IA-32 Firefox under SL-6x IA-32 from
Tools to Add-ons to Plugins:
Adobe Reader 9.4
Helix DNA Plugin: RealPlayer G2 Plug-In Compatible
iTunes Applicatiun Detector
]ava(TM) Plug-in 1.7.0_17
QuickTime Plug-in 7.2.0
Shockwave Flash 11.1 r1
VLC Multimedia Plugin (compatible Totem 2.28.5)
Windows Media Player Plug-in 10 (compatible; Totem)
At this point, the Java plugin is available and functioning in native
x86-64.
Are any of the other plugins available?
Is there a Firefox plugin "wrapper" that will run the IA-32 version
within an X86-64 browser?
