Hi All,
I have a doubt in question 17, pg 557:
17)Given a tag, simpleTag, whose handler is implemented using Simple Tag model and a tag, complexTag, whose handler is implemented using Classic Tag model.
Both tags are declared to be NON-EMPTY in the TLD.
Which JSP code snippets are valid uses of these tag?(Choose all that apply).
a)
This code snippet above is given as a correct answer, but if BOTH tags are supossed to be non-empty, why <my:complexTag /> is valid?
Tnx in advance

Non empty means that they can also be empty ! A tag whose body-content is not set to "empty" can also be empty.
<bob:say>hello</bob:say>
or
<bob:say />
<bob:say>hello</bob:say>
or
<bob:say />
