I have doubt in the followig question.
Source :- HFSJ chapter 7's Mock Exam (page 336)
<%@ page isELIgnored="true" %>
what is effect (choose all that apply)
A. Nothing, this page directive is NOT defined.
B. The directive turns off the evaluation of EL 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 a well-formed XML file.
D. The JSP containing this directive should NOT have any EL code evaluatd by JSP container.
E. This page directive will only turn off EL evaluation if the DD decalres a <el-ignored>true</el-ignored> element with a URL patter that includes this JSP.
Answer(in book) is E.
Is it really necessary we should have <el-ignored>true</el-ignored> in DD to use isELIgnored="true" in our JSPs....???
