In this Tutorial we are performing Session Tracking using SessionAware Interface and this interface is used by actions that want to access user's http session which will give them access to a Map where they can put objects that can be made available to subsequent requests.
Here we are not Performing any type of Validation so for validation part go for other Tutorials.

| Java Build Path Libraries |
you can't see struts2 jar here because we directly put it inside lib folder.
