Hi and welcome to LQ. Firstly what Linux distribution are you using. You need to set JAVA_HOME in your /etc/profile or .bash_profile. The JAVA_HOME variable should point to the directory containing your java installation. There are other methods depending on your distro.

I don't know as I never used linux and I have provided dedicated server with login password. I am using putty to login
From the output, the distribution that you are running is SUSE Linux Enterprise Server 10. You can set JAVA_HOME permanently by putting a little script similar to the one below in /etc/profile.d
Code:
export JAVA_HOME=/path/to/java/dir
Make sure you use the path of your own java directory. Save the file as java_home.sh in /etc/profile.d and make it executable by doing

I am really thankful to you
Plz let me know about classpath how can I see and add more in classpath
The classpath is an environment variable like JAVA_HOME. You can see what's in it by doing a "echo $CLASSPATH" in the shell. If there's no output, then it's not set. To set it, you use the same export statements that reddazz gave. If you just want to add a directory to your classpath, you would use an export statement, but you'd include the old classpath in it as well, e.g. "export CLASSPATH=$CLASSPATH:/foo", which says that the classpath should be set to the old value, but with /foo added. Directories are separated by colons in environment variables.
