JSP save button and page message

What Im trying to do is have a jsp page with a save button and when this save button is pressed the page shows a message which declares that "the data had been saved" and on the same page as where the button is.

Is there anywhere I can find out how to do that as it involves both javascript and jsp?

I think I should be using hidden input types but am not sure how to use these to ensure the message appears on the same page
