putting an array into a session?

[Guest_imported]

Is this valid...

String [] sarray={"one","two"}
session.setAttribute("sarray",sarray);

I dont think it is, since this is a sequence
of objects and not a specific object..

but I cant say for certain thats true.

An array itself is an object. It doesn't matter that it contains other objects, it can be used any place where an

Object

is expected. Personally I would prefer to use a

Collection

that way if you want to switch the data structure to a

LinkedList

or some type of synchronized collection later than it is transparent to the clients.

ok, I can put it into the session.. but how do
I get it back out..?

I've tried...

String [] s=session.getAttribute("array"

and I've tried just getting the String representation
of it.. It just looks like hash code..

You have to cast it to the proper type, just like every

Object

you get from the HttpSession.

String[] s = (String[])session.getAttribute("array");

I was casting it incorrectly! Thanks for your help!
