i m making a project in which i m using jsp as front end, java servlet,
java beans and mysql database.
now when i enter user_id and password on my login screen(jsp page) it
authenticates with the database. if it matches its ok but if not it
displays the sql error message on the internet explorer window. i want
that when such error generates a new jsp page(error.jsp)  opens
dynamically and show that error. can anybody suggest which additional
coding (or changes) do i require in my jsp page, servlet or java beans
to implement this concept.
OR u can suggest any valuable link(URL) on internet which can help me.
