Spring MVC: How to remove session attribute?

this will help As far as I understand, map.addAttribute(org.brahmaa.ads.util.impl.UserInfo.getPrincipal(session)); extracts the user attribute from the session and puts it into model. @SessionAttriubtes instructs Spring to do the same automatically. Therefore they conflicts. You should use only one of these approaches, not both simultaneously.

wish help you to fix your issue The spring security way seems the best way to me with access to specific roles also can be assigned. very good example given in http://www.mkyong.com/spring-security/spring-security-form-login-using-database/

may help you . I often do this to ensure performance on a session where it would take time to re-insert large numbers of 'static data' facts.

// Insert a fact and get a handle on to it
FactHandle handle = mySession.insert(myFact);

// Fire rules
mySession.fireAllRules();

// And retract the fact
mySession.retract(handle);
