Thanks Joakim!

Yes I do have a customized login module following JAAS spec. So it seems
the missing session is causing the problem. Then my question is: With
default configuration, does Jetty generate session automatically for
authenticated user? Or is my code responsible for doing that?

I actually published another question here
<http://jetty.4.x6.nabble.com/HttpServletRequest-Returns-NULL-Principal-After-Logging-In-td4968503.html>
which contains more details about my issue. Any help is highly appreciated!

Best
