Head First Servlets & JSP ...

[Jack Daniel]

Hi all,..

Firstly this is a great book
I know that many have this book...

I have a question regarding Question 6, page 330(mock exam) and in the answers it said 'E' as correct answer but i thought 'D' was the correct answer.

Any explaination(s)??
Thanks for your help

Jack,
Not all of us have read the book.
Maybe you could share the question and possible answers with us?

OK... i guess this is reg JSP 2.0 specs.

Given:

 <%@ page isELIgnored="true" %> 

what is the effect?

A. Nothing, this page directive is not defined

B. The directive turns off the evaluation of Expression Language code by the JSP container in all the web application's JSP's

C. The JSP containing this directive should be treated by the JSP container as a well formed XML file (hehehe.. funny )

D. The JSP containing this directive should NOT have any EL code evaluated by the JSP container

E. This page directive will only turn off EL evaluation if the DD declares a
<el-ignored> true </el-ignored> element with a URL pattern that includes this JSP.

Ben, ohh! i have leaked the answer before, in my first post

plz give your opinion(s)..
Thanks

PS: hope there are NO typos

JSP 3.3.2 (specifically Table JSP.3-1 EL Evaluation Settings for JSP Pages)
States that if that directive is set to true, it doesn't matter what's in the deployment descriptor, so I would say you are right.


Whenever you're in doubt, check the specs (the link is in my signature).

I never had the habit of looking at specifications.. but anyway better late than never.

So, i am correct
