I want to say thanks in advance for this help.

If you have cPanel, which seems to be the case :D you can install the JSP plugin from http://layer1.cpanel.net

That is Tomcat http://jakarta.apache.org/tomcat/index.html

So do not forget to read all the documentation and inside story of this Java Application Server before providing it in a production environment to your customers.

Ya I have Cpanel. I want to say thanks to masood for his help.

Please ensure to read all the documentation around.
JSP its a different kind of animal, its not like offer PHP or PERL.
Be sure that you know what you're doing.
