Installing Java SDK on Linux.

Download the latest Linux SDK 1.4.2 from Sun: 
j2sdk1.4.2_01.rpm.bin 

It's about 35MB.  Run it: 
sh j2sdk1.4.2.rpm.bin     
Agree to the license. It extracts the RPM file, making a file that
ends in .rpm.  
Then do:
rpm -i j2sdk1.4.2_01.rpm
as root to install the SDK.
It provides javac, java, appletviewer etc.

You will need to add /usr/java/j2sdk1.4.2_01/bin to PATH in your
.bash_profile file in your home directory because Sun has chosen not
to put the commands (java, javac etc) in one of the standard
directories.



Various IDEs exist, none of which I've tried.
emacs is Java-aware and does colorizing and auto indent etc.



Mozilla 1.4 or greater only works with jre1.4.2 (which is provided by
the above 1.4.2 version of the SDK).  You need to create a link from
Mozilla's plugin directory to the plugin file in the Java directory:
cd /usr/lib/mozilla-1.4.1/plugins/
ln -s /usr/java/j2sdk1.4.2_01/jre/plugin/i386/ns610-gcc32/libjavaplugin_oji.so

Update: Firefox 1.0 is a similar process.  with jdk 1.5

-------------------------------
Note that some of the versions as reflected in the directory names
might vary on your system.
