pass the session variable to 2 jsp simultaneously

I have 1 servlet and 2 jsp fils(say a.jsp , b.jsp ) , one jsp( b.jsp) is embeded in the other jsp( a.jsp ) by using <IFRAME > Tag .
After servlet has finished its job ( save results as session variable ) , it use getRequestDispatch("a.jsp" ).forward(req,res ) to redirect the request to a.jsp . Does both a.jsp and b.jsp can access the same session variables ?
My situation is a.jsp can retrieve the session variable , b.jsp can access too , but it seems that data is corrupted ( In my situation , my session variable is a byte[] )
Thanks

Your two jsp can certainly share a session, but since you can't control the order in which the request threads run, you will need to synchronize access to any variables that might be changed.
