You may want to try adding this to the header of your jsp: <meta http-equiv="expires" content="1" /> <meta http-equiv="pragma" content="no-cache" />
When the reload button is clicked, the browser should ask the user whether he/she wants to resend the entered information. It does not solve you problem completely (if the user chooses to resend the information, it is processed by the action again. But, on the other hand, you should take care of this e.g. in you validate method - maybe checking for existing name, id, etc.), but at least alerts the user, that he/she is doing someting repeatedly.
