Hi, I am developing an web application with JAAS, Spring and JPA. I will be validating the authentication of services by using following methods. 1. request.getUserPrincipal() 2. request.isUserInRole(). Both are working fine for sometime (apprx 1 min). After that both of them are returning NULL. ie. The request is losing the credentials. Please help me to fix this issue. Thanks, Lakshmi Narayanan.
