container managed authentication

[Yi-Xiong Zhou]

How do I perform additional process in struts at the time of authentication
if container managed authentication is used?

For example, after the user has just logged on, I want to initialize some
attributes in the session by loading in some data from the database. One way
to do that is to add a new method in Action to do such a process whenever a
new logon is detected. Then call that method at each implementation of
perform() method. Is there a better way to handle this task?
