Guys looks like i was not clear in my question earlier. My requirement is something like this
i make a call to struts 2 action which forwards the request to customer.jsp which populates the fields from CustomerInfo.java (data object). Say CustomerInfo has a field customerId .Assume its value was 100 when response was sent to user on UI. But some hacker/user changes the value to 300 to see some unauthorize data. What i am trying to ask here does struts 2 provide any inbuilt interceptor so that it can track those secure fields(assume i have annotated customerId with some annotation say @secureId) modification and throw error in case it is modified.
