basic question about <s:iterator>

[Nilesh Thali]

Sorry if this is too basic, but i seem to be missing something.
The iterator tag documentation says it iterates over the value on top of the stack.
I don't understand what this stack is and what is at the top of the stack.

Can i use the iterator tag to iterate over an object stored as a session attribute?

Any help much appreciated!

Hi,

what this stack is and what is at the top of the stack

In computer science, a stack is an abstract data type and data structure based on the principle of Last In First Out (LIFO).

A stack is an ordered list of items.

Can i use the iterator tag to iterate over an object stored as a session attribute?

Yes, you can use the iterator tag to iterate over an object stored as a session attribute.

sheesh - sorry if my question sounded that basic.
i meant i didn't know what stack was being referred to in the struts documentation, and when i asked "can i...", i meant "how do i do it"
sorry, should have been more accurate with my language.
anyways, the apache struts 2 mailing list (thru nabble) gave me the answer i was looking for.
thanks,
Nilesh
