Since I have tried many ways , all dont work!! I re-read the examples from
http://cwiki.apache.org/WW/iterator.html
and realize some things like :
quote "retrieves the value of the getDays() method of the current object on
the value stack and uses it to iterate over..."
quote "The following example uses a Bean tag and places it into the
ActionContext..."
quote " using a DAO obtained from the action class through OGNL..."
I thought, I just write class following POJO then in my JSP I just define it
as s:bean then s:iterator over it.
So how can I put my current object into value stack or into ActionContext or
into OGNL? or I am missing something here!
