How you change the environmental variables depends on which you are working in, because the shell is the environment.

Type whereis and the name of the program you are trying to run. It will give you the full path to that program.

Also, type:
echo $SHELL, and paste the results of it back here. Then we will be able to tell you exactly how to change the $PATH variable.

[root@COM04 /root]# whereis java
java: /usr/local/java
[root@COM04 /root]# echo $SHELL
/bin/bash


that was the output of the command syntax that you gave me..... thanx for the reply and the prompt reply guys!!! I really appreciate it.

Ok, in your home directory, there is a file called .bash_profile . If there isn't, you'd better make sure your account is set up correctly... So, you can either add this line at the end:

export PATH=${PATH}:/usr/local
or do this:
(by the way, this is personally how I would do it, since I like having a short $PATH...)

ln -s /usr/local/java /usr/bin/
(as root)

All of this is assuming "/usr/local/java" is the binary file, as opposed to a directory containing the java files... A good way to check that is to type /usr/local/java, and if it executes, follow the above directions... If it gives you an error, you need to find the binaries, and add their directory to your path, or link them to a place already in your path.
