Doubt on Tag Handlers

[Padma priya Gururajan]

Hi,
I have the following doubt in this jsp page:
<my:tag1>
<my:tag2>
<my:tag3/>
</my:tag2>
</my:tag1>
The tag handler for my:tag1 is Tag1Handler and extends TagSupport. The tag handler for my:tag2 is Tag2Handler and extends SimpleTagSupport. The tag handler for my:tag3 is Tag3Handler and extends TagSupport.

Now, how is it possible by Tag3Handler to use getParent method twice to gain access to the instance of TagHandler?

Can you clarify this?
With regards,

Hey,

Its not possible by using getParent method twice.

Hi,
That was the reply given in HFSJ in Page no:560(3rd Question).

Maybe I have the wrong HFSJ but in my version it says that you can use the getParent method twice for getting access or I misunderstand.

The errata for the book states

[550] question 3;
Option C is invalid.
Unfortunately, that leaves us with a mock question that doesn't have a valid answer.

You should go to the books errata on the Head First website and download all the mistakes and corrections. I found many when I used the book to study for the exam.

Also, when in doubt code the example or mock question and see if the answer is correct.

Thanks.. I will download the errata.

I don't want to learn something wrong...
