Just a short one - for installations of the java2 runtime environment, and the java2 sdk, you can go to http://java.sun.com/j2se/1.4.1/download.html and pick up the self-extracting binaries..
I recommend assuming root priviliges, then

1) put them somewhere sensible like /usr/java
2) chmod 755 *bin if necessary
3) run each one and accept the license agreements
4) symlink the required applications into your own bin folder eg ~/bin/
OR symlink them into a generic bin folder eg /usr/bin
In particular you will need javac to compile your .java sources.

For browser support, you will need to copy the .so file, (or create a link to it) into the plugins folder of your preferred browser. Much the same process as installing the Flash plugin..

that should get you started

here's an example

And this is how I enabled java in phoenix (moxilla-based) browser..

[root@baikal plugins]# ln -s /usr/java/j2re1.4.1_01/plugin/i386/ns600/libjavaplugin_oji.so libjavaplugin_oji.so

So it's dead simple.
I like working this way, cos I always have a squillion tabs open under Galeon, and it would be a pain if I had to close them all off whilst testing applets within a page/site.. so running Phoenix as an auxilliary Mozilla browser just for this java stuff is dead handy

another note

I should also note here that installing on RedHat 9 will only work if you use the newer j2re1.4.2. This is because it comes with a gcc 3.2 version, rather than gcc 2.9. I spent ages trying to get j2re1.4.1 to work, and it took someone on #mozillazine to point out what the problem was.

http://java.sun.com/j2se/1.4.2/download.html is the place to go for downloads.
