(Question 1).
In the chapter related to web application deployment there is a point made in the question in the end - which states that :

J2EE classes should not be overriden.


Is not overriding classes same as extending classes?. What is the difference. (Is it something as registering your own defined classes for the a given behaviour - like in struts - but I dont see any kind of registration of class names in any config file?)

For JSTL - we have classes defined for <c:forEach> action - . It is written in the specs that we can define our own classes and use them for such actions. Given that JSTL is part of J2EE framework - would not the above statement be wrong in that case?

Question 2
I had read that we can define our tags within <c:forEach> or <c:forToken>
Eg:


What I wish to know is : can the class which is responsible for simpleTag be able to access the currentVar ? - How does it access it?.


Thanks,
Shivani.

well I don't know in detail,
but your second question sounds like you want to use getParent() on the simpletag.

Look at the api for more info.
