Well typical for a web application :)
What you can do is if you have errors in the form data recieved, create a list of error messages [for each validation error for example] and set this list as request attribute and FORWARD to the error page/to the same page where user has entered the data. On this page get the request attribute, if it is not null then loop through the list and display error message.
Remember you need to forward to the jsp not redirect!
