Hi,

maybe I'm wrong but I'm quite sure "class" have to be a super class of "type"

so second option is wrong and third is ok.

and the explanation is also wrong

please tell me if I'm wrong

No, the given explanation is correct. Type can be a superclass. You may want to try it out.

thank you,
Paul.

It does not specify for answer 3 that com.abc.SubclassOfMyBean is a subclass for com.abc.MyBean (like in answer 2).

So the correct aswers would be:
2. <jsp:useBean id="bean1" scope="session" class="com.abc.SubclassOfMyBean" type="com.abc.MyBean"/> is a valid usage of useBean action. (Given that SubclassOfMyBean is a subclass of MyBean.)

3. <jsp:useBean id="bean1" scope="session" class="com.abc.MyBean" type="com.abc.SubclassOfMyBean"/> is a valid usage of useBean action.

5. <jsp:useBean id="bean1" type="com.abc.MyBean" /> is a valid usage of useBean action.


If the "(Given that SubclassOfMyBean is a subclass of MyBean.)" would be inside the question or next to aswer 3 as well, correct ones would be 2 and 5.
