How to deploy and run a simple servlet on websphere?

If you are new to websphere, it seems to be strange at least initially,to deploy the simple servlet. One way you can do is you need to generate a war file. For this you can use Application Assembly Tool that ships with websphere, it is simple if you use this tool, it walks you throwgh the steps to create a war file, and you can start a websphere console from "first steps" and you can deploy the file you created . And you can access your servlet by http://localhost:8090/your_web_application_context/servlet_url_mapping

This is very high level to get started, you can find more info in "infocenter" at ibm.com. You really need to do some research.
