so how 2 populate the entered values wen user clicks back button???
For the values to be automatically filled into the respective textboxes, they'll need to be properties in action which will show that page. And those properties need to be filled with the respective values. If that's not possible, then you'll have to manually fill the values of the textboxes using OGNL or EL...
I would like to add that you should use more informative topic name.
In your scenario you use two HTTP requests. The first for submiting form. The second for returning back to form (of course this back button is not browser's one!). The thing used to pass the information between HTTP requests is HTTP session. In case of struts 2 to use session you have your Action class to implement SessionAware interface, which will demand your class to implement method "setSession". The framework then use this method to pass your Action a Map which you can use to store all the fields when submitting form and retrieve them when returning back.
