Clarification regarding some core taglib usage

Hi

I created a jsp file with the following code:




The output is :

The forEach tag exposes a scoped variable called 'count', which is the position of the current element within the collection.
Family member #1 is Joe
Family member #2 is Rosy
Family member #3 is Petter
Family member #4 is Rob

I have the following queries:

a) From where are these numbers(1,2,3..) getting generated? What is the meaning of status.count? What is count?

b) Secondly, what is the meaning of ${pageScope.names}? Can't I simple write ${names} and pass the values in the String array? Where is this pageScope object coming from?

(a) Look up varStatus in the JSTL Specification. It references an object that contains information about the iteration status.

(b) By specifying pageScope, the search for the scoped variable is limited to page scope. Otherwise, the search spans all the scoped.
