In my DD i have errorpage declaration for both ArithmeticException and Throwable. when an ArithmeticException is thrown, it is always going to the jsp that is declared for Throwable. shouldn't it call the page that is declared for ArithmeticException ?

2. errorPage.jsp

3.arithmeticError.jsp

4.badPage.jsp (which throws ArithmeticException)

I think this is happening because the default try catch mechanism of JSP page wraps your ArithmeticException into a JasperException...
