Hi to All,
I am trying to make sample application and cant pass arraylist object on jsp page.
Could any body please guide me regarding to that?

Which will populate my arraylist(emplist) in ListDb class.
I call this method from ListAction.
//code for ListAction

How can i put Arraylist emp in request,and get arraylist object on Jsp page?

Provide a public getter for the list and it's available in the JSP.

Note that you're creating a new ArrayList then promptly replacing it with another one--you might as well skip the unused constructor call.

I'd also consider doing something different than instantiating the ListDB() directly, although it may not be very important yet--it can impede testability and flexibility, though.

(And is an empty list actually an error? It might be--but if not, maybe a different result name would express intent better?)
