Hi,

I'm trying to implement a "remember me" functionality in my website using Spring. The cookie and entry in the persistent_logins table are getting created correctly. Additionally, I can see that the correct user is being restored as the username is displayed at the top of the page.

However, once I try to access any information for this user when they return after they were "remembered", I get a NullPointerException. It looks as though the user isn't being set in the session again.

My applicationContext-security.xml contains the following:

<remember-me data-source-ref="dataSource" user-service-ref="userService"/>

...

<authentication-provider user-service-ref="userService" />

<jdbc-user-service id="userService" data-source-ref="dataSource" 
role-prefix="ROLE_"
users-by-username-query="select email as username, password, 1 as ENABLED from user where email=?" 
authorities-by-username-query="select user.id as id, upper(role.name) as authority from user, role, users_roles where users_roles.user_fk=id and users_roles.role_fk=role.name and user.email=?"/>

I thought it may have had something to do with users-by-username query but surely login wouldn't work correctly if this query was incorrect?

Any help on this would be greatly appreciated.

Thanks, gearoid.
