Hi,

I tried to use this code in my servlet:

			

			

			HttpSession session = request.getSession(false);
			

			if (session == null)
			

			{
			

			//redirect to login page
			

			}
			

		

			

			

			Error: 500
			

			Location: /WebTest/companysetup
			

			Internal Servlet Error:
			

			

			java.lang.NullPointerException
