who can explain the item to me?

[Niu Xiuyuan]

a question in a mock:
Attribute flush of jsp include action is a mandatory attribute
1) yes
2) no
3) Only the first time a jsp include action appears in a page

what means "mandatory attribute"?

[ersin eser]

<jsp:include page="path" flush="true" />

page and flush are the attribute of <jsp:include> tag.
In version 1.1 of JSP Spec it was required to set it to true
In version 1.2 of JSP Spec it is not required and defaults to false.

[Niu Xiuyuan]

but the answer is "no".
could u explain it for me?

[Reda Mokrane]

Hi !!!
mandatory attribute = needful attribute = obligatory attribute

The question: Attribute flush of jsp include action is a mandatory attribute
The answer is "no" because flush of jsp include action is not a mandatory attribute mean you can use <jsp:include page="path" /> without the flush attribute <jsp:include page="path" flush="true" />.
correct me if i'm wrong

[Axel Janssen]

It is not mandatory to set, because it defaults to false, if we omit it (as Ersin said).
correct me if I am wrong.

[Reda Mokrane]

Axel,
you are correct.
as I said

The answer is "no" because flush of jsp include action is not a mandatory attribute mean you can use <jsp:include page="path" /> without the flush attribute <jsp:include page="path" flush="true" />.

mandatory attribute = needful attribute = obligatory attribute = required attribute.
I agree with all others, it is not a required (mandatory) attribute.
