@samir: You can find the documentation on the project page:
http://tomcat.apache.org/
Tomcat is a bit of a beast, so be prepared to do a lot of reading, testing, and experimentation before you're ready to deploy anything.
As mentioned, your question is not going to yield much in the way of suggestions. You need to do the groundwork yourself, and then ask about
specific issues that you're not able to resolve through exhaustive personal effort.
