在J2EE中,如果a是b的父类,b是c的父类,c是d的父类,他们都在包mypackage 中。则以下正确的是()
- A<jsp:usebean id=”mybean” scop=”page” class=”mypackage.d” type=”b”>
- B<jsp:useBean id=”mybean” scop=”page” class=”mypackage.d” type=”Obiect”/>
- C<jsp:useBean id=”mybean” scop=”page” class=”mypackage.d” type=”mypackage.a”/>
- D<jsp:usebean id=”mybean” scop=”page” class=”mypackage.d” type=”a”/>
