Chapter 13


page 239 Last paragraph:

getParameterValues has a simple String argument not a string Array - it returns a String array

"Similarly. paramValues uses the getParameterValues(String [] name)"

should be

"Similarly. paramValues uses the getParameterValues(String name)"


page 241

Second Quizlet requiring knowledge of "EL operators properties and collection classes"
appears BEFORE that discussion.


13.2.1
Shouldn't it be mentioned somewhere that for non-collection 'properties' JavaBean style getXxx() accessors and setXxx() manipulators are required?


Last paragraph:
'0th element' ??? It's still the first element (otherwise what follows the 0th element?) or the element at index 0.


page 242

13.2.2
"Fixed Point" is used to describe data types that represent 'real numbers'
http://en.wikipedia.org/wiki/Fixed-point_arithmetic
not numbers restricted to the representation of whole numbers/integral values. Integer values don't require a "point" as no fractional value is stored.

Phrasing of Question 2:
"Which statement best expresses the purpose of a tag library descriptor (TLD) in an EL function?"

How can a tag library descriptor (a name that usually refers to the .tld file) be in an EL function?
Based on the desired answer the question should be phrased:

"Which statement best expresses the purpose of the <function> element in the tag library descriptor (TLD)"

Furthermore (with regards to the answer) the function names never appear between '<>' (angle brackets) in a JSP but inside '${}', so are there actually any tags involved?
Granted the EL expression appears as an element body but the function always appears inside an EL expression.
