We have bioinformatics visualization applications that require a java
plugin enabled web browser. The only plugin from Oracle/Sun Java that
works is:

End quote from java.com
Note the USA Dept of Homeland Security has issues with earlier versions
of Java (and perhaps with the above). However, the default Java loaded
by SL6x for a x86-64 is:
[ykarant@ahprc3 ~]$ java -version
java version "1.6.0_24"
OpenJDK Runtime Environment (IcedTea6 1.11.3)
(rhel-1.48.1.11.3.el6_2-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)
and although firefox reports that the jre plugin is enabled
(that is /usr/lib/mozilla/plugins has libnpjp2.so as a soft link to the
correct file from the above URL source (
/usr/java/default/lib/i386/libnpjp2.so )
[again -- 32-bit version for Java applet and Java Web Start support we
need] and is reported by firefox as enabled)
the java in fact does not run. This is not a firefox issue nor a java
issue per se, as the visualization application does work on other
distros (I have seen it, as well as MS Win 7, because the bioinformatics
applications using java were working), but so far not on SL6x x86-64.
Has anyone else encountered this problem and does anyone have a work-around?
Thanks for any information.
