i ran the example on tomcat 7.0.34 and it gave runtime exception as follows:

avax.el.ELException: The identifier [this] is not a valid Java identifier as required by section 1.19 of the EL specification (Identifier ::= Java language identifier). This check can be disabled by setting the system property org.apache.el.parser.SKIP_IDENTIFIER_CHECK to true.

Please what is the correct answer for the question

Are you talking about ${requestScope.sessions.this}? This is an incorrect option.

oh yeah sorry my bad.

That
${not(sessionScope.length)}
doesn't work in glassfish. Throws IllegalStateException: PWC6243: Cannot access session scope in page that does not participate in any session

You are right, this doesn't work anymore. The question has now been updated.

thank you for your feedback!

Hi,
just want to notify a typo in the explanation of the 5th option.

It says "Ideally, the argument to the not function must be a booean."
but should be "Ideally, the argument to the not function must be a boolean."

Happy holidays
Barbara

Fixed.

thank you for your feedback!
Paul.
