Hot on the heels of the success of getting sound to work with FireFox, I am on to getting Java applets to run.
When I go to a page with a Java applet, I get the little Rubik's cube- like icon that says I can click to download. So I do, but FireFox says it can't find it, so I have to install manually.
I click on Manual install and I'm taken to a page that allows me to download the RPM within a ".bin" file. That's new to me, but I'm game. I download it and follow the install instructions. It makes me create a /usr/java directory, and open the .bin file there.
I have to go through a whole license text file, but in the end it says it's installed.
I check in the directory, and there's a jre directory and an RPM file. I wonder why the RPM file is there if it's already installed. I try to install using RPM, and it says it's already installed, so I decide I believe it.
I re-open FireFox... and going to the same web page I was at before with the Java applet, I'm presented with the same screen saying I need to install the plug in.
What am I doing wrong with the installation?

Simple way "yum install j2re mozilla-j2re" from dag's repository. It sets everything up for you.
The sun java rpm unpacks files, but doesn't really do much that's useful. It doesn't set any of the environment variables or add java to the user's path, or install itself with /sbin/aternatives

Simple way "yum install j2re mozilla-j2re" from dag's repository. It sets everything up for you.
After some fiddling I discovered that I had to remove the j2re that I had installed manually by using rpm -e. I also deleted the directory as well, just to be sure.
And then I installed using the YUM command above, and it installed nice and easy. It even automatically connected with FireFox so that I didn't have to do any extra configurations within FireFox. I just fired up the browser and I had Java applets running.
A small side note, just for possible future reference, is that the reason I didn't find the Java runtime environment on Dag in the first place is that I searched for it using "jre" instead of "j2re". D'oh!
Thank you everyone for helping out, including those who offered suggestions on how to edit FireFox's configuration, which I'm lucky to have not needed, but it's great that everyone had such helpful advice.

I just dealt w/ this this A.M. w/ SuSE 8.2 :-). I think you need to put a soft-link in your mozilla plugins directory as such:
(cd /opt/mozilla/plugins/; ln -s /usr/lib/java/jre/plugin/i386/mozilla/javaplugin_oji.so javaplugin_oji.so)
You need to be root to do this. If CentOS installs the Java Runtime Environment (jre) in a different place (other than /usr/lib/java, apparently /usr/java for you), use that path instead of the one I gave you. I got this info from the mozilla website. YMMV & all that.
Dave, First, confirm that Java is installed.
cd /usr/java/
you should have a directory "jre1.5.x.x.x" or whatever the current version. That directory should have some stuff in it:
<SNIP> [ahull@hal jre1.5.0_02]$ ls bin COPYRIGHT lib man README Welcome.html CHANGES javaws LICENSE plugin THIRDPARTYLICENSEREADME.txt <!SNIP>
If it does not, then Java is not installed yet. I recommend not downloading the RPM.
One you get it installed, then you have to copy the plugin to the proper directory in Firefox.
a symbolic link would do this nicely.
ln -s n -s /<java dir>/plugin/i386/ns7/libjavaplugin_oji.so /<firefox dir>/plugins/
Then enable the java checkbox in firefox preferences and you're set.
The java website has some decent instructions too: http://java.com/en/download/help/5000010500.xml#selfextracting

oops...
ln -s /<java dir>/plugin/i386/ns7/libjavaplugin_oji.so /<firefox dir>/plugins/
where did that extra "n -s" come from? who knows
