Hello,

On 64 bit Linux running 2.6.18-164.el5, I installed the jdk1.7.0_09 and the install defaulted to /usr/java/jdk1.0_09. It completed with some errors (that I foolishly did not document). Before running the install, I used rpm to uninstall the old version that was running in a completely different directory.

Now Firefox is not working though Java seems to be installed and running. Advice from the Java Test website recommends removing old and creating new sym links to the Java plug-in, but I cannot find the old or new plug-in files!

I've run out of ideas on how to troubleshoot/fix Firefox. It's a 64 bit OS is it even using a plug-in?

Any ideas advice would be great, thanks!

Jennifer

Are you able to launch firefox, I mean is it opening but lacking java plugins or you can't even open it?

did you fallow the instructions on the wiki?
http://wiki.centos.org/HowTos/JavaOnCentOS

mind you on the OLD centOS 5.8 ( the ONLY 5 version that is supported )
assuming that this is CentOS 5.8 do to the .el5 in the post
if this is in fact RHEL 5.8 then see the RHN knowledge-base on the red hat site- the FULL instructions are there
firefox-10.0.8-1.el5
yes firefox 10 AND NOT 15 is used

the java 1.7 might not work well on the old firefox10

i would use the yum repo install for java then run
( see the Oracle java web site , download page)
that will make sure that you have a version that is compatible installed


as to the plugin
that might be fun
it is called " alternatives"
the /usr/lib64/browser-plugins
has a link for java

BUT to the 32 bit version in /etc/alternatives
that in turn is a link to /usr/lib/java/???????
and someplace in there is the java.so
it is a very round a bout mess to use a 32 bit plugin ( might be the 64 bit ? unknown ) on a ? 32 bit firefox on a 64 bit OS
--- it is a MESS ----

one that i removed on my ScientificLinux6.3 install
by installing the custom 64 bit firefox 15 build
and using the 64 bit java and flash plugins
