In HFSJ PAGE 405,it says with the include directive,the source of included thing becomes PART of the page with the include directive
I think it means that include directive can include dynamic page.
But why the option A of question 12 of page 430 is wrong?

Hi Avseq,

I first checked the errata list .

Well, the answer you are looking for is also on page 430 (look the note for Option A) where you have <%@ include ...> and not <jsp:include ...>.

I think include directive means "<%@include ....%>",so I think the page 405 that says it can include dynamic page.
Do I think wrong?

Hi Avseq,

p. 430 Question 12 is not asking anything about include directive but only about dynamic content in a JSP. Hence the explanation why Answer C and not Answer A which is given on p. 430 is correct.

For those who don't have the HFSJ book I put the question here:


QUESTION:

How would you include dynamic content in a JSP, similar to a server-side include (SSI)? (Choose all that apply)

A. <%@ include file="/segments/footer.jspf" %>
B. <jsp:forward page="/segments/footer.jspf"/>
C. <jsp:include page="/segments/footer.jspf"/>
D. RequestDispatcher dispatcher = request.getRequestDispatcher("/segments/footer.jspf"); dispatcher.include(request, response);


ANSWER: C

Option A is incorrect because it uses an include directive, which is for static includes that happen at translation time.


Regards,
Darya
