In Java, how do I set a return type if an exception occurs?

Try this one

public ActionForward Login(ActionMapping mapping, ActionForm form,
        HttpServletRequest request, HttpServletResponse response) {
    MigForm migForm = (MigForm) form;// TODO Auto-generated method stub

    Connection con = null;
    Statement st = null;
    ResultSet rs = null;

    String uname=migForm.getUname();
    String pwd=migForm.getPwd();

    try{
        Class.forName("oracle.jdbc.driver.OracleDriver");
        con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:XE","uname","pwd");
        if(con.isClosed())
        {
            return mapping.findForward("success");
        }

        //st=con.createStatement();

        }catch(Exception err){

        System.out.println(err.getMessage());
        }


            return mapping.findForward("failure");



}
