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?
