Well, you can place the StudentID into the HttpSession, there is also a nice Annotation @SessionAttribute you can use to have Spring go into the HttpSession and get that value out in the other controller.

Another approach is if you are using Spring Security, you can have the StudentID in the User object (UserDetails) which any Controller can get that User object through the SecurityContextUtils class as well as in Spring 3.0 use Spring Expression Language and use the "principal.xxxx" to evaluate to returning the studentId.
