I recently got the 3.6.4 version of Firefox for (Red Hat Enterprise)
Linux (5). Java does not seem to exist anymore, though it worked until I
got the latest version. Java is no longer in the plugin list nor is it
in any menu.

I downloaded the latest Java, jre-6u20-linux-i586-rpm and installed it
with no trouble. It still does not appear in the plugin list or any of
the menus. If I look at

/usr/lib/mozilla/plugins

I see

lrwxrwxrwx 1 root root 39 Jun 22 21:00 libflashplayer.so ->
/usr/lib/flash-plugin/libflashplayer.so
lrwxrwxrwx 1 root root 53 Jun 23 10:51 libjavaplugin_oji.so ->
/usr/java/latest/plugin/i386/ns7/libjavaplugin_oji.so
lrwxrwxrwx 1 root root 39 May 11 15:13 nphelix.so ->
/opt/real/RealPlayer/mozilla/nphelix.so
lrwxrwxrwx 1 root root 40 May 11 15:13 nphelix.xpt ->
/opt/real/RealPlayer/mozilla/nphelix.xpt

that it is there. The other three plugins appear, but not java.

What should I check to resolve this?

jre Plugin name for that release is libnpjp2.so. Results from about:plugins

Java(TM) Plug-in 1.6.0_20

    File: libnpjp2.so
    Version: 
    The next generation Java plug-in for Mozilla browsers.

I am running Mandriva Linux and the link is

$ cd /usr/lib/mozilla/plugins
$ ls -al libnpjp2.so

<snip>   libnpjp2.so -> /usr/java/default/lib/i386/libnpjp2.so

I have the jdk package, instead of the jre.  The java plugin opera and
firefox use here is ...
$ ll /usr/lib/mozilla/plugins/libnpjp2.so
lrwxrwxrwx 1 root root 45 2010-03-27 19:53 /usr/lib/mozilla/plugins/libnpjp2.so -> ../../../java/latest/jre/lib/i386/libnpjp2.so

Thank you. That fixed it. I wish the Firefox web site would have
mentioned it.

Why is firefox required to know plugin file names.

The plugin vendor's site should mention it in it's install instructions,
or in the packages file documentation.

Maybe they do, but I could not find them. They discuss only out of date
releases.

Yep, I did a quick look and did not see the name.

Tell them about the problem in the package and install documentation.
Might save you time on next update.

It's there, but much harder to find than the old instructions:

http://java.sun.com/javase/6/webnotes/install/jre/manual-plugin-install-linux.html

I was directed there from an article on the Mozilla site about 
installing java plugins.
