SQLException never thrown

Hej,

Hvorfor virker det her ikke. Jeg får en fejl som siger at SQLException is never thrown

try {
       
    Vector vi = new Vector();
   
    vi.addElement(request.getParameter("produkt"));       
    vi.addElement(request.getParameter("form"));
    vi.addElement(request.getParameter("type"));
    vi.addElement(request.getParameter("description"));
   
    d.insertUpdate("INSERT INTO under_under_produkter (Product,Form,Type,Description) VALUES(?,?,?,?)", vi);
       
    } catch (SQLException s) {
    System.out.println("<h3>SQL fejl: " + s.toString() + " "
    + s.getErrorCode() + " " + s.getSQLState() + "</h3>");
    }
