What I did for that was store the userId in an ASO and then use a threaded
HiveMind service (which can look up the ASO through the
ApplicationStateManager) to query for the User object as it is needed (lazy
initialization) based on the userId stored in the ASO...

interface="com.martialware.web.service.SecurityContext">

</service-point>
public class SecurityContextImpl implements SecurityContext
{
private ApplicationStateManager stateManager;
private SecurityService securityService;
private UserRepository userRepository;
private User user;
public void authenticate( String userName, String password ) throws
InvalidPasswordException,
InvalidUserIdException
{
securityService.authenticate( userName, password );
getUserSession().setUserId( userName );
}
public boolean isAuthenticated()
{
final UserSession userSession = getUserSession();
return userSession.getUserId() != null;
}
public void logout()
{
getUserSession().setUserId( null );
}
public User getUser()
{
if( user == null )
{
if( isAuthenticated() )
{
user = userRepository.getUserByUserId(
getUserSession().getUserId() );
}
}
return user;
}
private UserSession getUserSession()
{
final UserSession userSession = ( UserSession ) stateManager.get(
UserSession.NAME );
return userSession;
}
public void setUserRepository( UserRepository userRepository )
{
this.userRepository = userRepository;
}
public void setSecurityService( SecurityService securityService )
{
this.securityService = securityService;
}
public void setStateManager( ApplicationStateManager stateManager )
{
this.stateManager = stateManager;
}
}

Subject: Re: hibernate detached objects as persistent page properties
Thanks for the code. I'll take a look and see if I can incorporate
this in my application.
One further question, how have people dealt with detached hibernate
objects in the session? In my case, which I imagine is a common case
for a lot of people, after the user has authenticated, I store the
User object in my Visit object. The user object is a hibernate
detached entity. As the user performs actions on the site, I update
the user object including updating lazy loaded collections that map
the user object to other tables. I suppose I have to reattach the
User object for each request but this doesn't seem terribly efficient.
What have others done?
