Unavailable session in Controller Servlet.....

Hi Pals,I am doing the following in my controller servlet(using a front controller design pattern):
1.After front end validation for username and password,i then do
my Authentication in my Controller servlet by checking the database for the name and password entered.
If valid user,then i get the session object from the request as follows:
class controllerServlet extends HttpServlet
HttpSession session;
BigBean oneBean;
Hashtable refHash;

public void doPost(---------)
if(Ok button is pressed on LogOn screen do authentication)
if( user is valid after checking)
// the problem is after checking that session is NOT null
below ,i still found out that it is null in the second
inner-if block(i.e.if(refHash==null)).And i had to get my session again to set the refHash in a session scope.
//this block is executed after authentication and after seeing homepage
oneBean = new BigBean();

//i had to do :session=request.getSession(true);
refHash = new Hashtable( );

Please help,checking that session is NOT null before executing a block which binds some objects to session using session.setAttribute(name,obj).And finding session to be null in the block later.Cheers.
I agree. Here's the link:
