installing j2ee sdk  directly from binary  file is easier for novice users

in linux  (and most Unix like systems) you can set  environment variable  like this:

for example:
export JAVA_HOME=/user/arash_r/bin/java

you can check environment variable values using echo command

for example

path is path  in most linux distributions and is case sensitive

in Debian linux for making  variables persistence during reboots
you can define them in:

There is NO DEFAULT WAY of setting  the variables  in Debian, but you may use the /etc/environment file  that can be parsed in scripts that use bourne compatible shells (like bash).


Now, this file may be parsed by /etc/profile adding following line there:

. /etc/environment

the above is copyied from "Debian Maintenance HOWTO"

wish you best
and happy java  experience over Linux

can I know where are you using Java and Linux?

Installing JDK is pretty easy from linux  GUI. If you have ubuntu which is debian base, or you have another linux distributor which has Synaptic Package Manager, you can search for JDK and then install  it.

If you do not want to use Synaptic Package Manager or you do not have it, you should download JDK with bin extension and install it in this way:

After that, you should set  your PATH and CLASSPATH in this way:
export PATH=/home/<user>/jdk1.5.0_04/bin
export CLASSPATH=/home/<user>/jdk1.5.0_04/lib

Also you can read install.html and system-configurations.html in java  web site.
