Make a �registration� form that collects a first name, last name, and email address. Send the data to a servlet that displays it.If the user fails to supply a value for any of the fields in the form, you should redisplay the form but with an error message saying that the value is missing.
Don�t make the user re-enter values that they�ve entered already.
