HFSJ - Error in Exercise?

Hi All,
I found the following question in the excercise of chapter 7.

<%@ page isELIgnored="true" %>

What is the eefect? (Choose all that apply.)
A. Nothing, this page directive is NOT defined.

B. The directive turns off the evalution of Expresiion Language code by the JSP container in all of the web application's JSPs.

C. The JSP containing this directive should be treated by the JSP container as well-formed XML file.

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

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

Ans: E

But I think the answer should be D.
Am I right?

EL is enabled by default and you have to explicitly set in the DD use a directive to disable it. So even I feel answer D is correct!

I checked the errata and did not find this error. Is this really an error and if it is how can it be added to the errata so others won't have to go thru the same issue.

Hi I would like to you inform one thing.. from which part EL ignored will decide.. whether it is from web.xml or @page directive IsElIgnored attribute..

If both sets same meaning then there is no problem..

If both differ..


Could any one come up with spec..?

The EL ignorance declaration in web.xml would apply to complete web app where as the EL declaration in jsp just applies to that particular jsp page.

If you specify "true" in web.xml to ignore el & you specify false in all the jsps to isELIgnored then the jsp declaration would take precedence over the web.xml declaration & all the ELs in all the JSPs would be evaluated.
