retriving an ArrayList from Session Object

In the my first jsp i have the line.

session.setAttribute("list",alist);

That sets an ArrayList called alist(already created) into the session Object.

In the my next jsp is the line.

ArrayList arrayList = session.getAttribute("list");

I get the following error message when compiling.

"CheckPayRollAxis.jsp": Error #: 354 : incompatible types; found: java.lang.Object, required: java.util.ArrayList at line 14

Please tell me how to retreive the arrayList.
